Description

condor_submitis the program for submitting jobs for execution under HTCondor. condor_submitrequires a
submit description file which contains commands to direct the queuing of jobs. One submit description
file may contain specifications for the queuing of many HTCondor jobs at once. A single invocation of
condor_submitmay cause one or more clusters. A cluster is a set of jobs specified in the submit
description file between queuecommands for which the executable is not changed. It is advantageous to
submit multiple jobs as a single cluster because:

* Only one copy of the checkpoint file is needed to represent all jobs in a cluster until they begin
execution.

* There is much less overhead involved for HTCondor to start the next job in a cluster than for
HTCondor to start a new cluster. This can make a big difference when submitting lots of short jobs.

Multiple clusters may be specified within a single submit description file. Each cluster must specify a
single executable.

The job ClassAd attribute ClusterIdidentifies a cluster.

The submit description fileargument is the path and file name of the submit description file. If this
optional argument is missing or is the dash character (-), then the commands are taken from standard
input. If -is specified for the submit description file, -verboseis implied; this can be overridden by
specifying -terse.

Note that submission of jobs from a Windows machine requires a stashed password to allow HTCondor to
impersonate the user submitting the job. To stash a password, use the condor_store_credcommand. See the
manual page for details.

For lengthy lines within the submit description file, the backslash () is a line continuation character.
Placing the backslash at the end of a line causes the current line's command to be continued with the
next line of the file. Submit description files may contain comments. A comment is any line beginning
with a pound character ( # ).

Options

-terse

Terse output - display JobId ranges only.

-verbose

Verbose output - display the created job ClassAd

-unused

As a default, causes no warnings to be issued about user-defined macros not being used within the
submit description file. The meaning reverses (toggles) when the configuration variable
WARN_ON_UNUSED_SUBMIT_FILE_MACROSis set to the non default value of False. Printing the warnings can
help identify spelling errors of submit description file commands. The warnings are sent to stderr.

-name schedd_name

Submit to the specified condor_schedd. Use this option to submit to a condor_scheddother than the
default local one. schedd_nameis the value of the NameClassAd attribute on the machine where the
condor_schedddaemon runs.

-remote schedd_name

Submit to the specified condor_schedd, spooling all required input files over the network connection.
schedd_nameis the value of the NameClassAd attribute on the machine where the condor_schedddaemon
runs. This option is equivalent to using both -nameand -spool.

-addr <ip:port>

Submit to the condor_scheddat the IP address and port given by the sinful stringargument <ip:port>.

-pool pool_name

Look in the specified pool for the condor_scheddto submit to. This option is used with -nameor
-remote.

-disable

Disable file permission checks when submitting a job for read permissions on all input files, such as
those defined by commands inputand transfer_input_files, as well as write permission to output files,
such as a log file defined by logand output files defined with outputor transfer_output_files.

-password passphrase

Specify a password to the MyProxyserver.

-debug

Cause debugging information to be sent to stderr, based on the value of the configuration variable
TOOL_DEBUG.

-append command

Augment the commands in the submit description file with the given command. This command will be
considered to immediately precede the queuecommand within the submit description file, and come after
all other previous commands. If the commandspecifies a queuecommand, as in the example

condor_submit mysubmitfile -append "queue input in A, B, C"

then the entire -appendcommand line option and its arguments are converted to

condor_submit mysubmitfile -queue input in A, B, C

The submit description file is not modified. Multiple commands are specified by using the
-appendoption multiple times. Each new command is given in a separate -appendoption. Commands with
spaces in them will need to be enclosed in double quote marks.

-batch-name batch_name

Set the batch name for this submit. The batch name is displayed by condor_q-batch. It is intended for
use by users to give meaningful names to their jobs and to influence how condor_qgroups jobs for
display. Use of this argument takes precedence over a batch name specified in the submit description
file itself.

-spool

Spool all required input files, job event log, and proxy over the connection to the condor_schedd.
After submission, modify local copies of the files without affecting your jobs. Any output files for
completed jobs need to be retrieved with condor_transfer_data.

-dump filename

Sends all ClassAds to the specified file, instead of to the condor_schedd.

-interactive

Indicates that the user wants to run an interactive shell on an execute machine in the pool. This is
equivalent to creating a submit description file of a vanilla universe sleep job, and then running
condor_ssh_to_jobby hand. Without any additional arguments, condor_submit with the -interactive flag
creates a dummy vanilla universe job that sleeps, submits it to the local scheduler, waits for the job
to run, and then launches condor_ssh_to_jobto run a shell. If the user would like to run the shell on
a machine that matches a particular requirementsexpression, the submit description file is specified,
and it will contain the expression. Note that all policy expressions specified in the submit
description file are honored, but any executableor universecommands are overwritten to be sleep and
vanilla. The job ClassAd attribute InteractiveJobis set to Trueto identify interactive jobs for
condor_startdpolicy usage.

-dry-run file

Parse the submit description file, sending the resulting job ClassAd to the file given by file, but do
not submit the job(s). This permits observation of the job specification, and it facilitates debugging
the submit description file contents. If fileis -, the output is written to stdout.

-maxjobs number-of-jobs

If the total number of jobs specified by the submit description file is more than the integer value
given by number-of-jobs, then no jobs are submitted for execution and an error message is generated. A
0 or negative value for the number-of-jobscauses no limit to be imposed.

-single-cluster

If the jobs specified by the submit description file causes more than a single cluster value to be
assigned, then no jobs are submitted for execution and an error message is generated.

-stm method

Specify the method use to move a sandbox into HTCondor. methodis one of stm_use_schedd_onlyor
stm_use_transferd.

<submit-variable>=<value>

Defines a submit command or submit variable with a value, and parses it as if it was placed at the
beginning of the submit description file. The submit description file is not changed. To correctly
parse the condor_submit command line, this option must be specified without white space characters
before and after the equals sign (=), or the entire option must be surrounded by double quote marks.

-queue queue_arguments

A command line specification of how many jobs to queue, which is only permitted if the submit
description file does not have a queuecommand. The queue_argumentsare the same as may be within a
submit description file. The parsing of the queue_argumentsfinishes at the end of the line or when a
dash character (-) is encountered. Therefore, its best placement within the command line will be at
the end of the command line.

On a Unix command line, the shell expands file globs before parsing occurs.

Submit Description File Commands

Note: more information on submitting HTCondor jobs can be found here: 2.5.

As of version 8.5.6, the condor_submitlanguage supports multi-line values in commands. The syntax is the
same as the configuration language (see more details here: 3.3.5).

Each submit description file describes one or more clusters of jobs to be placed in the HTCondor
execution pool. All jobs in a cluster must share the same executable, but they may have different input
and output files, and different program arguments. The submit description file is generally the last
command-line argument to condor_submit. If the submit description file argument is omitted,
condor_submitwill read the submit description from standard input.

The submit description file must contain at least one executablecommand and at least one queuecommand.
All of the other commands have default actions.

Note that a submit file that contains more than one executable command will produce multiple clusters
when submitted. This is not generally recommended, and is not allowed for submit files that are run as
DAG node jobs by condor_dagman.

The commands which can appear in the submit description file are numerous. They are listed here in
alphabetical order by category.

BASIC COMMANDS

arguments = <argument_list>

List of arguments to be supplied to the executable as part of the command line.

In the javauniverse, the first argument must be the name of the class containing main.

There are two permissible formats for specifying arguments, identified as the old syntax and the new
syntax. The old syntax supports white space characters within arguments only in special circumstances;
when used, the command line arguments are represented in the job ClassAd attribute Args. The new
syntax supports uniform quoting of white space characters within arguments; when used, the command
line arguments are represented in the job ClassAd attribute Arguments.

Old Syntax

In the old syntax, individual command line arguments are delimited (separated) by space characters. To
allow a double quote mark in an argument, it is escaped with a backslash; that is, the two character
sequence \" becomes a single double quote mark within an argument.

Further interpretation of the argument string differs depending on the operating system. On Windows,
the entire argument string is passed verbatim (other than the backslash in front of double quote
marks) to the Windows application. Most Windows applications will allow spaces within an argument
value by surrounding the argument with double quotes marks. In all other cases, there is no further
interpretation of the arguments.

Example:

arguments = one \"two\" 'three'

Produces in Unix vanilla universe:

argument 1: one
argument 2: "two"
argument 3: 'three'

New Syntax

Here are the rules for using the new syntax:

1. The entire string representing the command line arguments is surrounded by double quote marks.
This permits the white space characters of spaces and tabs to potentially be embedded within a
single argument. Putting the double quote mark within the arguments is accomplished by escaping it
with another double quote mark.

2. The white space characters of spaces or tabs delimit arguments.

3. To embed white space characters of spaces or tabs within a single argument, surround the entire
argument with single quote marks.

4. To insert a literal single quote mark, escape it within an argument already delimited by single
quote marks by adding another single quote mark.

Example:

arguments = "3 simple arguments"

Produces:

argument 1: 3
argument 2: simple
argument 3: arguments

Another example:

arguments = "one 'two with spaces' 3"

Produces:

argument 1: one
argument 2: two with spaces
argument 3: 3

And yet another example:

arguments = "one ""two"" 'spacey &rdquo;quoted&rdquo; argument'"

Produces:

argument 1: one
argument 2: "two"
argument 3: spacey 'quoted' argument

Notice that in the new syntax, the backslash has no special meaning. This is for the convenience of
Windows users.

environment = <parameter_list>

List of environment variables.

There are two different formats for specifying the environment variables: the old format and the new
format. The old format is retained for backward-compatibility. It suffers from a platform-dependent
syntax and the inability to insert some special characters into the environment.

The new syntax for specifying environment values:

1. Put double quote marks around the entire argument string. This distinguishes the new syntax from
the old. The old syntax does not have double quote marks around it. Any literal double quote marks
within the string must be escaped by repeating the double quote mark.

2. Each environment entry has the form

3. Use white space (space or tab characters) to separate environment entries.

4. To put any white space in an environment entry, surround the space and as much of the
surrounding entry as desired with single quote marks.

5. To insert a literal single quote mark, repeat the single quote mark anywhere inside of a section
surrounded by single quote marks.

Example:

environment = "one=1 two=""2"" three='spacey &rdquo;quoted&rdquo; value'"

Produces the following environment entries:

one=1
two="2"
three=spacey 'quoted' value

Under the old syntax, there are no double quote marks surrounding the environment specification. Each
environment entry remains of the form

Under Unix, list multiple environment entries by separating them with a semicolon (;). Under Windows,
separate multiple entries with a vertical bar (|). There is no way to insert a literal semicolon under
Unix or a literal vertical bar under Windows. Note that spaces are accepted, but rarely desired,
characters within parameter names and values, because they are treated as literal characters, not
separators or ignored white space. Place spaces within the parameter list only if required.

A Unix example:

environment = one=1;two=2;three="quotes have no 'special' meaning"

This produces the following:

one=1
two=2
three="quotes have no 'special' meaning"

If the environment is set with the environmentcommand andgetenvis also set to true, values specified
with environmentoverride values in the submitter's environment (regardless of the order of the
environmentand getenvcommands).

error = <pathname>

A path and file name used by HTCondor to capture any error messages the program would normally write
to the screen (that is, this file becomes stderr). A path is given with respect to the file system of
the machine on which the job is submitted. The file is written (by the job) in the remote scratch
directory of the machine where the job is executed. When the job exits, the resulting file is
transferred back to the machine where the job was submitted, and the path is utilized for file
placement. If not specified, the default value of /dev/nullis used for submission to a Unix machine.
If not specified, error messages are ignored for submission to a Windows machine. More than one job
should not use the same error file, since this will cause one job to overwrite the errors of another.
The error file and the output file should not be the same file as the outputs will overwrite each
other or be lost. For grid universe jobs, errormay be a URL that the Globus tool
globus_url_copyunderstands.

executable = <pathname>

An optional path and a required file name of the executable file for this job cluster. Only one
executablecommand within a submit description file is guaranteed to work properly. More than one often
works.

If no path or a relative path is used, then the executable file is presumed to be relative to the
current working directory of the user as the condor_submit command is issued.

If submitting into the standard universe, then the named executable must have been re-linked with the
HTCondor libraries (such as via the condor_compilecommand). If submitting into the vanilla universe
(the default), then the named executable need not be re-linked and can be any process which can run in
the background (shell scripts work fine as well). If submitting into the Java universe, then the
argument must be a compiled .classfile.

getenv = <True |False>

If getenvis set to True, then condor_submit will copy all of the user's current shell environment
variables at the time of job submission into the job ClassAd. The job will therefore execute with the
same set of environment variables that the user had at submit time. Defaults to False.

input = <pathname>

HTCondor assumes that its jobs are long-running, and that the user will not wait at the terminal for
their completion. Because of this, the standard files which normally access the terminal, (stdin,
stdout, and stderr), must refer to files. Thus, the file name specified with inputshould contain any
keyboard input the program requires (that is, this file becomes stdin). A path is given with respect
to the file system of the machine on which the job is submitted. The file is transferred before
execution to the remote scratch directory of the machine where the job is executed. If not specified,
the default value of /dev/nullis used for submission to a Unix machine. If not specified, input is
ignored for submission to a Windows machine. For grid universe jobs, inputmay be a URL that the Globus
tool globus_url_copyunderstands.

Note that this command does notrefer to the command-line arguments of the program. The command-line
arguments are specified by the argumentscommand.

log = <pathname>

Use logto specify a file name where HTCondor will write a log file of what is happening with this job
cluster, called a job event log. For example, HTCondor will place a log entry into this file when and
where the job begins running, when the job produces a checkpoint, or moves (migrates) to another
machine, and when the job completes. Most users find specifying a logfile to be handy; its use is
recommended. If no logentry is specified, HTCondor does not create a log for this cluster. If a
relative path is specified, it is relative to the current working directory as the job is submitted or
the directory specified by submit command initialdiron the submit machine.

log_xml = <True |False>

If log_xmlis True, then the job event log file will be written in ClassAd XML. If not specified, XML
is not used. Note that the file is an XML fragment; it is missing the file header and footer. Do not
mix XML and non-XML within a single file. If multiple jobs write to a single job event log file,
ensure that all of the jobs specify this option in the same way.

notification = <Always |Complete |Error |Never>

Owners of HTCondor jobs are notified by e-mail when certain events occur. If defined by Always, the
owner will be notified whenever the job produces a checkpoint, as well as when the job completes. If
defined by Complete, the owner will be notified when the job terminates. If defined by Error, the
owner will only be notified if the job terminates abnormally, or if the job is placed on hold because
of a failure, and not by user request. If defined by Never(the default), the owner will not receive e-
mail, regardless to what happens to the job. The HTCondor User's manual documents statistics included
in the e-mail.

notify_user = <email-address>

Used to specify the e-mail address to use when HTCondor sends e-mail about a job. If not specified,
HTCondor defaults to using the e-mail address defined by

job-owner@UID_DOMAIN

where the configuration variable UID_DOMAINis specified by the HTCondor site administrator. If
UID_DOMAINhas not been specified, HTCondor sends the e-mail to:

job-owner@submit-machine-name

output = <pathname>

The outputfile captures any information the program would ordinarily write to the screen (that is,
this file becomes stdout). A path is given with respect to the file system of the machine on which the
job is submitted. The file is written (by the job) in the remote scratch directory of the machine
where the job is executed. When the job exits, the resulting file is transferred back to the machine
where the job was submitted, and the path is utilized for file placement. If not specified, the
default value of /dev/nullis used for submission to a Unix machine. If not specified, output is
ignored for submission to a Windows machine. Multiple jobs should not use the same output file, since
this will cause one job to overwrite the output of another. The output file and the error file should
not be the same file as the outputs will overwrite each other or be lost. For grid universe jobs,
outputmay be a URL that the Globus tool globus_url_copyunderstands.

Note that if a program explicitly opens and writes to a file, that file should notbe specified as the
outputfile.

priority = <integer>

An HTCondor job priority can be any integer, with 0 being the default. Jobs with higher numerical
priority will run before jobs with lower numerical priority. Note that this priority is on a per user
basis. One user with many jobs may use this command to order his/her own jobs, and this will have no
effect on whether or not these jobs will run ahead of another user's jobs.

Note that the priority setting in an HTCondor submit file will be overridden by condor_dagmanif the
submit file is used for a node in a DAG, and the priority of the node within the DAG is non-zero (see
2.10.9for more details).

queue [<int expr>]

Places zero or more copies of the job into the HTCondor queue.

queue

[<int expr>] [<varname>] in[slice] <list of items>Places zero or more copies of the job in the queue
based on items in a <list of items>

queue

[<int expr>] [<varname>] matching[files | dirs] [slice] <list of items with file globbing>] Places
zero or more copies of the job in the queue based on files that match a <list of items with file
globbing>

queue

[<int expr>] [<list of varnames>] from[slice] <file name> | <list of items>] Places zero or more
copies of the job in the queue based on lines from the submit file or from <file name>

The optional argument <int expr>specifies how many times to repeat the job submission for a given set
of arguments. It may be an integer or an expression that evaluates to an integer, and it defaults to
1. All but the first form of this command are various ways of specifying a list of items. When these
forms are used <int expr>jobs will be queued for each item in the list. The in, matchingand
fromkeyword indicates how the list will be specified.

* inThe list of items is an explicit comma and/or space separated <list of items>. If the <list of
items>begins with an open paren, and the close paren is not on the same line as the open, then the
list continues until a line that begins with a close paren is read from the submit file.

* matchingEach item in the <list of items with file globbing>will be matched against the names of
files and directories relative to the current directory, the set of matching names is the resulting
list of items.

* filesOnly filenames will matched.

* dirsOnly directory names will be matched.

* from<file name> | <list of items>Each line from <file name>or <list of items>is a single item,
this allows for multiple variables to be set for each item. Lines from <file name>or <list of
items>will be split on comma and/or space until there are values for each of the variables
specified in <list of varnames>. The last variable will contain the remainder of the line. When the
<list of items>form is used, the list continues until the first line that begins with a close
paren, and lines beginning with pound sign ('#') will be skipped. When using the <file name>form,
if the <file name>ends with |, then it will be executed as a script whatever the script writes to
stdoutwill be the list of items. The optional argument <varname>or <list of varnames>is the name or
names of of variables that will be set to the value of the current item when queuing the job. If no
<varname>is specified the variable ITEM will be used. Leading and trailing whitespace be trimmed.
The optional argument <slice>is a python style slice selecting only some of the items in the list
of items. Negative step values are not supported.

A submit file may contain more than one queuestatement, and if desired, any commands may be placed
between subsequent queuecommands, such as new input, output, error, initialdir, or argumentscommands.
This is handy when submitting multiple runs into one cluster with one submit description file.

Specifies which HTCondor universe to use when running this job. The HTCondor universe specifies an
HTCondor execution environment.

The vanillauniverse is the default (except where the configuration variable DEFAULT_UNIVERSEdefines it
otherwise), and is an execution environment for jobs which do not use HTCondor's mechanisms for taking
checkpoints; these are ones that have not been linked with the HTCondor libraries. Use the
vanillauniverse to submit shell scripts to HTCondor.

The standarduniverse tells HTCondor that this job has been re-linked via condor_compilewith the
HTCondor libraries and therefore supports taking checkpoints and remote system calls.

The scheduleruniverse is for a job that is to run on the machine where the job is submitted. This
universe is intended for a job that acts as a metascheduler and will not be preempted.

The localuniverse is for a job that is to run on the machine where the job is submitted. This universe
runs the job immediately and will not preempt the job.

The griduniverse forwards the job to an external job management system. Further specification of the
griduniverse is done with the grid_resourcecommand.

The javauniverse is for programs written to the Java Virtual Machine.

The vmuniverse facilitates the execution of a virtual machine.

The paralleluniverse is for parallel jobs (e.g. MPI) that require multiple machines in order to run.

The dockeruniverse runs a docker container as an HTCondor job.

COMMANDS FOR MATCHMAKING

rank = <ClassAd Float Expression>

A ClassAd Floating-Point expression that states how to rank machines which have already met the
requirements expression. Essentially, rank expresses preference. A higher numeric value equals better
rank. HTCondor will give the job the machine with the highest rank. For example,

request_memory = max({60, Target.TotalSlotMemory})
rank = Memory

asks HTCondor to find all available machines with more than 60 megabytes of memory and give to the job
the machine with the most amount of memory. The HTCondor User's Manual contains complete information
on the syntax and available attributes that can be used in the ClassAd expression.

request_cpus = <num-cpus>

A requested number of CPUs (cores). If not specified, the number requested will be 1. If specified,
the expression

&& (RequestCpus <= Target.Cpus)

is appended to the requirementsexpression for the job.

For pools that enable dynamic condor_startdprovisioning, specifies the minimum number of CPUs
requested for this job, resulting in a dynamic slot being created with this many cores.

request_disk = <quantity>

The requested amount of disk space in KiB requested for this job. If not specified, it will be set to
the job ClassAd attribute DiskUsage. The expression

&& (RequestDisk <= Target.Disk)

is appended to the requirementsexpression for the job.

For pools that enable dynamic condor_startdprovisioning, a dynamic slot will be created with at least
this much disk space.

Characters may be appended to a numerical value to indicate units. Kor KBindicates KiB, numbers of
bytes. Mor MBindicates MiB, numbers of bytes. Gor GBindicates GiB, numbers of bytes. Tor TBindicates
TiB, numbers of bytes.

request_memory = <quantity>

The required amount of memory in MiB that this job needs to avoid excessive swapping. If not specified
and the submit command vm_memoryis specified, then the value specified for vm_memorydefines
request_memory. If neither request_memorynor vm_memoryis specified, the value is set by the
configuration variable JOB_DEFAULT_REQUESTMEMORY. The actual amount of memory used by a job is
represented by the job ClassAd attribute MemoryUsage.

For pools that enable dynamic condor_startdprovisioning, a dynamic slot will be created with at least
this much RAM.

The expression

&& (RequestMemory <= Target.Memory)

is appended to the requirementsexpression for the job.

request_<name> = <quantity>

The required amount of the custom machine resource identified by <name>that this job needs. The custom
machine resource is defined in the machine's configuration. Machines that have available GPUs will
define <name>to be GPUs.

requirements = <ClassAd Boolean Expression>

The requirements command is a boolean ClassAd expression which uses C-like operators. In order for any
job in this cluster to run on a given machine, this requirements expression must evaluate to true on
the given machine.

For scheduler and local universe jobs, the requirements expression is evaluated against the
SchedulerClassAd which represents the the condor_schedddaemon running on the submit machine, rather
than a remote machine. Like all commands in the submit description file, if multiple requirements
commands are present, all but the last one are ignored. By default, condor_submit appends the
following clauses to the requirements expression:

1. Arch and OpSys are set equal to the Arch and OpSys of the submit machine. In other words: unless
you request otherwise, HTCondor will give your job machines with the same architecture and
operating system version as the machine running condor_submit .

2. Cpus >=RequestCpus, if the job ClassAd attribute RequestCpusis defined.

3. Disk >=RequestDisk, if the job ClassAd attribute RequestDiskis defined. Otherwise, Disk
>=DiskUsage is appended to the requirements. The DiskUsageattribute is initialized to the size of
the executable plus the size of any files specified in a transfer_input_filescommand. It exists to
ensure there is enough disk space on the target machine for HTCondor to copy over both the
executable and needed input files. The DiskUsageattribute represents the maximum amount of total
disk space required by the job in kilobytes. HTCondor automatically updates the DiskUsageattribute
approximately every 20 minutes while the job runs with the amount of space being used by the job on
the execute machine.

4. Memory >=RequestMemory, if the job ClassAd attribute RequestMemoryis defined.

5. If Universe is set to Vanilla, FileSystemDomain is set equal to the submit machine's
FileSystemDomain. View the requirements of a job which has already been submitted (along with
everything else about the job ClassAd) with the command condor_q -l; see the command reference for
condor_qon page . Also, see the HTCondor Users Manual for complete information on the syntax and
available attributes that can be used in the ClassAd expression.

FILE TRANSFER COMMANDS

dont_encrypt_input_files = < file1,file2,file... >

A comma and/or space separated list of input files that are notto be network encrypted when
transferred with the file transfer mechanism. Specification of files in this manner overrides
configuration that would use encryption. Each input file must also be in the list given by
transfer_input_files. When a path to an input file or directory is specified, this specifies the path
to the file on the submit side. A single wild card character (*) may be used in each file name.

dont_encrypt_output_files = < file1,file2,file... >

A comma and/or space separated list of output files that are notto be network encrypted when
transferred back with the file transfer mechanism. Specification of files in this manner overrides
configuration that would use encryption. The output file(s) must also either be in the list given by
transfer_output_filesor be discovered and to be transferred back with the file transfer mechanism.
When a path to an output file or directory is specified, this specifies the path to the file on the
execute side. A single wild card character (*) may be used in each file name.

encrypt_execute_directory = <True |False>

Defaults to False. If set to True, HTCondor will encrypt the contents of the remote scratch directory
of the machine where the job is executed. This encryption is transparent to the job itself, but
ensures that files left behind on the local disk of the execute machine, perhaps due to a system
crash, will remain private. In addition, condor_submit will append to the job's requirementsexpression

&& (TARGET.HasEncryptExecuteDirectory)

to ensure the job is matched to a machine that is capable of encrypting the contents of the execute
directory. This support is limited to Windows platforms that use the NTFS file system and Linux
platforms with the ecryptfs-utilspackage installed.

encrypt_input_files = < file1,file2,file... >

A comma and/or space separated list of input files that are to be network encrypted when transferred
with the file transfer mechanism. Specification of files in this manner overrides configuration that
would notuse encryption. Each input file must also be in the list given by transfer_input_files. When
a path to an input file or directory is specified, this specifies the path to the file on the submit
side. A single wild card character (*) may be used in each file name. The method of encryption
utilized will be as agreed upon in security negotiation; if that negotiation failed, then the file
transfer mechanism must also fail for files to be network encrypted.

encrypt_output_files = < file1,file2,file... >

A comma and/or space separated list of output files that are to be network encrypted when transferred
back with the file transfer mechanism. Specification of files in this manner overrides configuration
that would notuse encryption. The output file(s) must also either be in the list given by
transfer_output_filesor be discovered and to be transferred back with the file transfer mechanism.
When a path to an output file or directory is specified, this specifies the path to the file on the
execute side. A single wild card character (*) may be used in each file name. The method of encryption
utilized will be as agreed upon in security negotiation; if that negotiation failed, then the file
transfer mechanism must also fail for files to be network encrypted.

max_transfer_input_mb = <ClassAd Integer Expression>

This integer expression specifies the maximum allowed total size in MiB of the input files that are
transferred for a job. This expression does notapply to grid universe, standard universe, or files
transferred via file transfer plug-ins. The expression may refer to attributes of the job. The special
value -1 indicates no limit. If not defined, the value set by configuration variable
MAX_TRANSFER_INPUT_MBis used. If the observed size of all input files at submit time is larger than
the limit, the job will be immediately placed on hold with a HoldReasonCodevalue of 32. If the job
passes this initial test, but the size of the input files increases or the limit decreases so that the
limit is violated, the job will be placed on hold at the time when the file transfer is attempted.

max_transfer_output_mb = <ClassAd Integer Expression>

This integer expression specifies the maximum allowed total size in MiB of the output files that are
transferred for a job. This expression does notapply to grid universe, standard universe, or files
transferred via file transfer plug-ins. The expression may refer to attributes of the job. The special
value -1 indicates no limit. If not set, the value set by configuration variable
MAX_TRANSFER_OUTPUT_MBis used. If the total size of the job's output files to be transferred is larger
than the limit, the job will be placed on hold with a HoldReasonCodevalue of 33. The output will be
transferred up to the point when the limit is hit, so some files may be fully transferred, some
partially, and some not at all.

output_destination = <destination-URL>

When present, defines a URL that specifies both a plug-in and a destination for the transfer of the
entire output sandbox or a subset of output files as specified by the submit command
transfer_output_files. The plug-in does the transfer of files, and no files are sent back to the
submit machine. The HTCondor Administrator's manual has full details.

should_transfer_files = <YES |NO |IF_NEEDED >

The should_transfer_filessetting is used to define if HTCondor should transfer files to and from the
remote machine where the job runs. The file transfer mechanism is used to run jobs which are not in
the standard universe (and can therefore use remote system calls for file access) on machines which do
not have a shared file system with the submit machine. should_transfer_filesequal to YESwill cause
HTCondor to always transfer files for the job. NOdisables HTCondor's file transfer mechanism.
IF_NEEDEDwill not transfer files for the job if it is matched with a resource in the same
FileSystemDomainas the submit machine (and therefore, on a machine with the same shared file system).
If the job is matched with a remote resource in a different FileSystemDomain, HTCondor will transfer
the necessary files.

For more information about this and other settings related to transferring files, see the HTCondor
User's manual section on the file transfer mechanism.

Note that should_transfer_filesis not supported for jobs submitted to the grid universe.

skip_filechecks = <True |False>

When True, file permission checks for the submitted job are disabled. When False, file permissions are
checked; this is the behavior when this command is not present in the submit description file. File
permissions are checked for read permissions on all input files, such as those defined by commands
inputand transfer_input_files, and for write permission to output files, such as a log file defined by
logand output files defined with outputor transfer_output_files.

stream_error = <True |False>

If True, then stderris streamed back to the machine from which the job was submitted. If False,
stderris stored locally and transferred back when the job completes. This command is ignored if the
job ClassAd attribute TransferErris False. The default value is False. This command must be used in
conjunction with error, otherwise stderrwill sent to /dev/nullon Unix machines and ignored on Windows
machines.

stream_input = <True |False>

If True, then stdinis streamed from the machine on which the job was submitted. The default value is
False. The command is only relevant for jobs submitted to the vanilla or java universes, and it is
ignored by the grid universe. This command must be used in conjunction with input, otherwise stdinwill
be /dev/nullon Unix machines and ignored on Windows machines.

stream_output = <True |False>

If True, then stdoutis streamed back to the machine from which the job was submitted. If False,
stdoutis stored locally and transferred back when the job completes. This command is ignored if the
job ClassAd attribute TransferOutis False. The default value is False. This command must be used in
conjunction with output, otherwise stdoutwill sent to /dev/nullon Unix machines and ignored on Windows
machines.

transfer_executable = <True |False>

This command is applicable to jobs submitted to the grid and vanilla universes. If
transfer_executableis set to False, then HTCondor looks for the executable on the remote machine, and
does not transfer the executable over. This is useful for an already pre-staged executable; HTCondor
behaves more like rsh. The default value is True.

transfer_input_files = < file1,file2,file... >

A comma-delimited list of all the files and directories to be transferred into the working directory
for the job, before the job is started. By default, the file specified in the executablecommand and
any file specified in the inputcommand (for example, stdin) are transferred.

When a path to an input file or directory is specified, this specifies the path to the file on the
submit side. The file is placed in the job's temporary scratch directory on the execute side, and it
is named using the base name of the original path. For example, /path/to/input_filebecomes
input_filein the job's scratch directory.

A directory may be specified by appending the forward slash character (/) as a trailing path
separator. This syntax is used for both Windows and Linux submit hosts. A directory example using a
trailing path separator is input_data/. When a directory is specified with the trailing path
separator, the contents of the directory are transferred, but the directory itself is not transferred.
It is as if each of the items within the directory were listed in the transfer list. When there is no
trailing path separator, the directory is transferred, its contents are transferred, and these
contents are placed inside the transferred directory.

For grid universe jobs other than HTCondor-C, the transfer of directories is not currently supported.

Symbolic links to files are transferred as the files they point to. Transfer of symbolic links to
directories is not currently supported.

For vanilla and vm universe jobs only, a file may be specified by giving a URL, instead of a file
name. The implementation for URL transfers requires both configuration and available plug-in.

transfer_output_files = < file1,file2,file... >

This command forms an explicit list of output files and directories to be transferred back from the
temporary working directory on the execute machine to the submit machine. If there are multiple files,
they must be delimited with commas. Setting transfer_output_filesto the empty string ( "" ) means that
no files are to be transferred.

For HTCondor-C jobs and all other non-grid universe jobs, if transfer_output_filesis not specified,
HTCondor will automatically transfer back all files in the job's temporary working directory which
have been modified or created by the job. Subdirectories are not scanned for output, so if output from
subdirectories is desired, the output list must be explicitly specified. For grid universe jobs other
than HTCondor-C, desired output files must also be explicitly listed. Another reason to explicitly
list output files is for a job that creates many files, and the user wants only a subset transferred
back.

For grid universe jobs other than with grid type condor, to have files other than standard output and
standard error transferred from the execute machine back to the submit machine, do use
transfer_output_files, listing all files to be transferred. These files are found on the execute
machine in the working directory of the job.

When a path to an output file or directory is specified, it specifies the path to the file on the
execute side. As a destination on the submit side, the file is placed in the job's initial working
directory, and it is named using the base name of the original path. For example,
path/to/output_filebecomes output_filein the job's initial working directory. The name and path of the
file that is written on the submit side may be modified by using transfer_output_remaps. Note that
this remap function only works with files but not with directories.

A directory may be specified using a trailing path separator. An example of a trailing path separator
is the slash character on Unix platforms; a directory example using a trailing path separator is
input_data/. When a directory is specified with a trailing path separator, the contents of the
directory are transferred, but the directory itself is not transferred. It is as if each of the items
within the directory were listed in the transfer list. When there is no trailing path separator, the
directory is transferred, its contents are transferred, and these contents are placed inside the
transferred directory.

For grid universe jobs other than HTCondor-C, the transfer of directories is not currently supported.

Symbolic links to files are transferred as the files they point to. Transfer of symbolic links to
directories is not currently supported.

transfer_output_remaps < &ldquo; name newname ; name2 newname2 ... &rdquo;>

This specifies the name (and optionally path) to use when downloading output files from the completed
job. Normally, output files are transferred back to the initial working directory with the same name
they had in the execution directory. This gives you the option to save them with a different path or
name. If you specify a relative path, the final path will be relative to the job's initial working
directory.

namedescribes an output file name produced by your job, and newnamedescribes the file name it should
be downloaded to. Multiple remaps can be specified by separating each with a semicolon. If you wish to
remap file names that contain equals signs or semicolons, these special characters may be escaped with
a backslash. You cannot specify directories to be remapped.

when_to_transfer_output = < ON_EXIT |ON_EXIT_OR_EVICT >

Setting when_to_transfer_outputequal to ON_EXITwill cause HTCondor to transfer the job's output files
back to the submitting machine only when the job completes (exits on its own).

The ON_EXIT_OR_EVICToption is intended for fault tolerant jobs which periodically save their own state
and can restart where they left off. In this case, files are spooled to the submit machine any time
the job leaves a remote site, either because it exited on its own, or was evicted by the HTCondor
system for any reason prior to job completion. The files spooled back are placed in a directory
defined by the value of the SPOOLconfiguration variable. Any output files transferred back to the
submit machine are automatically sent back out again as input files if the job restarts.

POLICY COMMANDS

max_retries = <integer>

The maximum number of retries allowed for this job (must be non-negative). If the job fails (does not
exit with the success_exit_codeexit code) it will be retried up to max_retriestimes (unless retries
are ceased because of the retry_untilcommand). If max_retriesis not defined, and either retry_untilor
success_exit_codeis, the value of DEFAULT_JOB_MAX_RETRIESwill be used for the maximum number of
retries.

The combination of the max_retries, retry_until, and success_exit_codecommands causes an appropriate
OnExitRemoveexpression to be automatically generated. If retry command(s) and on_exit_removeare both
defined, the OnExitRemoveexpression will be generated by OR'ing the expression specified in
OnExitRemoveand the expression generated by the retry commands.

retry_until <Integer | ClassAd Boolean Expression>

An integer value or boolean expression that prevents further retries from taking place, even if
max_retrieshave not been exhausted. If retry_untilis an integer, the job exiting with that exit code
will cause retries to cease. If retry_untilis a ClassAd expression, the expression evaluating to
Truewill cause retries to cease.

success_exit_code = <integer>

The exit code that is considered successful for this job. Defaults to 0 if not defined.

Note: non-zero values of success_exit_codeshould generally not be used for DAG node jobs.At the
present time, condor_dagmandoes not take into account the value of success_exit_code. This means that,
if success_exit_codeis set to a non-zero value, condor_dagmanwill consider the job failed when it
actually succeeds. For single-proc DAG node jobs, this can be overcome by using a POST script that
takes into account the value of success_exit_code(although this is not recommended). For multi-proc
DAG node jobs, there is currently no way to overcome this limitation.

hold = <True |False>

If holdis set to True, then the submitted job will be placed into the Hold state. Jobs in the Hold
state will not run until released by condor_release. Defaults to False.

keep_claim_idle = <integer>

An integer number of seconds that a job requests the condor_scheddto wait before releasing its claim
after the job exits or after the job is removed.

The process by which the condor_scheddclaims a condor_startdis somewhat time-consuming. To amortize
this cost, the condor_scheddtries to reuse claims to run subsequent jobs, after a job using a claim is
done. However, it can only do this if there is an idle job in the queue at the moment the previous job
completes. Sometimes, and especially for the node jobs when using DAGMan, there is a subsequent job
about to be submitted, but it has not yet arrived in the queue when the previous job completes. As a
result, the condor_scheddreleases the claim, and the next job must wait an entire negotiation cycle to
start. When this submit command is defined with a non-negative integer, when the job exits, the
condor_scheddtries as usual to reuse the claim. If it cannot, instead of releasing the claim, the
condor_scheddkeeps the claim until either the number of seconds given as a parameter, or a new job
which matches that claim arrives, whichever comes first. The condor_startdin question will remain in
the Claimed/Idle state, and the original job will be "charged" (in terms of priority) for the time in
this state.

leave_in_queue = <ClassAd Boolean Expression>

When the ClassAd Expression evaluates to True, the job is not removed from the queue upon completion.
This allows the user of a remotely spooled job to retrieve output files in cases where HTCondor would
have removed them as part of the cleanup associated with completion. The job will only exit the queue
once it has been marked for removal (via condor_rm, for example) and the leave_in_queueexpression has
become False. leave_in_queuedefaults to False.

As an example, if the job is to be removed once the output is retrieved with condor_transfer_data,
then use

leave_in_queue = (JobStatus == 4) && ((StageOutFinish =?= UNDEFINED) ||\

(StageOutFinish == 0))

next_job_start_delay = <ClassAd Boolean Expression>

This expression specifies the number of seconds to delay after starting up this job before the next
job is started. The maximum allowed delay is specified by the HTCondor configuration variable
MAX_NEXT_JOB_START_DELAY, which defaults to 10 minutes. This command does not apply to scheduleror
localuniverse jobs.

This command has been historically used to implement a form of job start throttling from the job
submitter's perspective. It was effective for the case of multiple job submission where the transfer
of extremely large input data sets to the execute machine caused machine performance to suffer. This
command is no longer useful, as throttling should be accomplished through configuration of the
condor_schedddaemon.

on_exit_hold = <ClassAd Boolean Expression>

The ClassAd expression is checked when the job exits, and if True, places the job into the Hold state.
If False(the default value when not defined), then nothing happens and the on_exit_removeexpression is
checked to determine if that needs to be applied.

For example: Suppose a job is known to run for a minimum of an hour. If the job exits after less than
an hour, the job should be placed on hold and an e-mail notification sent, instead of being allowed to
leave the queue.

on_exit_hold = (time() - JobStartDate) < (60 * $(MINUTE))

This expression places the job on hold if it exits for any reason before running for an hour. An e-
mail will be sent to the user explaining that the job was placed on hold because this expression
became True.

periodic_*expressions take precedence over on_exit_*expressions, and *_holdexpressions take precedence
over a *_removeexpressions.

Only job ClassAd attributes will be defined for use by this ClassAd expression. This expression is
available for the vanilla, java, parallel, grid, local and scheduler universes. It is additionally
available, when submitted from a Unix machine, for the standard universe.

on_exit_hold_reason = <ClassAd String Expression>

When the job is placed on hold due to the on_exit_holdexpression becoming True, this expression is
evaluated to set the value of HoldReasonin the job ClassAd. If this expression is UNDEFINEDor produces
an empty or invalid string, a default description is used.

on_exit_hold_subcode = <ClassAd Integer Expression>

When the job is placed on hold due to the on_exit_holdexpression becoming True, this expression is
evaluated to set the value of HoldReasonSubCodein the job ClassAd. The default subcode is 0. The
HoldReasonCodewill be set to 3, which indicates that the job went on hold due to a job policy
expression.

on_exit_remove = <ClassAd Boolean Expression>

The ClassAd expression is checked when the job exits, and if True(the default value when undefined),
then it allows the job to leave the queue normally. If False, then the job is placed back into the
Idle state. If the user job runs under the vanilla universe, then the job restarts from the beginning.
If the user job runs under the standard universe, then it continues from where it left off, using the
last checkpoint.

For example, suppose a job occasionally segfaults, but chances are that the job will finish
successfully if the job is run again with the same data. The on_exit_removeexpression can cause the
job to run again with the following command. Assume that the signal identifier for the segmentation
fault is 11 on the platform where the job will be running.

on_exit_remove = (ExitBySignal == False) || (ExitSignal != 11) This expression lets the job leave the
queue if the job was not killed by a signal or if it was killed by a signal other than 11, representing
segmentation fault in this example. So, if the exited due to signal 11, it will stay in the job queue. In
any other case of the job exiting, the job will leave the queue as it normally would have done.

As another example, if the job should only leave the queue if it exited on its own with status 0, this
on_exit_removeexpression works well:

on_exit_remove = (ExitBySignal == False) && (ExitCode == 0) If the job was killed by a signal or exited
with a non-zero exit status, HTCondor would leave the job in the queue to run again.

periodic_*expressions take precedence over on_exit_*expressions, and *_holdexpressions take precedence
over a *_removeexpressions.

Only job ClassAd attributes will be defined for use by this ClassAd expression.

periodic_hold = <ClassAd Boolean Expression>

This expression is checked periodically when the job is not in the Held state. If it becomes True, the
job will be placed on hold. If unspecified, the default value is False.

periodic_*expressions take precedence over on_exit_*expressions, and *_holdexpressions take precedence
over a *_removeexpressions.

Only job ClassAd attributes will be defined for use by this ClassAd expression. Note that, by default,
this expression is only checked once every 60 seconds. The period of these evaluations can be adjusted
by setting the PERIODIC_EXPR_INTERVAL, MAX_PERIODIC_EXPR_INTERVAL, and
PERIODIC_EXPR_TIMESLICEconfiguration macros.

periodic_hold_reason = <ClassAd String Expression>

When the job is placed on hold due to the periodic_holdexpression becoming True, this expression is
evaluated to set the value of HoldReasonin the job ClassAd. If this expression is UNDEFINEDor produces
an empty or invalid string, a default description is used.

periodic_hold_subcode = <ClassAd Integer Expression>

When the job is placed on hold due to the periodic_holdexpression becoming true, this expression is
evaluated to set the value of HoldReasonSubCodein the job ClassAd. The default subcode is 0. The
HoldReasonCodewill be set to 3, which indicates that the job went on hold due to a job policy
expression.

periodic_release = <ClassAd Boolean Expression>

This expression is checked periodically when the job is in the Held state. If the expression becomes
True, the job will be released.

periodic_remove = <ClassAd Boolean Expression>

This expression is checked periodically. If it becomes True, the job is removed from the queue. If
unspecified, the default value is False.

See the Examples section of this manual page for an example of a periodic_removeexpression.

periodic_*expressions take precedence over on_exit_*expressions, and *_holdexpressions take precedence
over a *_removeexpressions. So, the periodic_removeexpression takes precedent over the
on_exit_removeexpression, if the two describe conflicting actions.

COMMANDS SPECIFIC TO THE STANDARD UNIVERSE

allow_startup_script = <True |False>

If True, a standard universe job will execute a script instead of submitting the job, and the
consistency check to see if the executable has been linked using condor_compileis omitted. The
executablecommand within the submit description file specifies the name of the script. The script is
used to do preprocessing before the job is submitted. The shell script ends with an execof the job
executable, such that the process id of the executable is the same as that of the shell script. Here
is an example script that gets a copy of a machine-specific executable before the exec.

#! /bin/sh

# get the host name of the machine
$host=`uname -n`

# grab a standard universe executable designed specifically
# for this host
scp elsewhere@cs.wisc.edu:${host} executable

# The PID MUST stay the same, so exec the new standard universe process.
exec executable ${1+"$@"} If this command is not present (defined), then the value defaults to false.

append_files = file1, file2, ...

If your job attempts to access a file mentioned in this list, HTCondor will force all writes to that
file to be appended to the end. Furthermore, condor_submit will not truncate it. This list uses the
same syntax as compress_files, shown above.

This option may yield some surprising results. If several jobs attempt to write to the same file,
their output may be intermixed. If a job is evicted from one or more machines during the course of its
lifetime, such an output file might contain several copies of the results. This option should be only
be used when you wish a certain file to be treated as a running log instead of a precise result.

This option only applies to standard-universe jobs.

buffer_files < &ldquo; name (size,block-size) ; name2 (size,block-size) ... &rdquo; >

buffer_size <bytes-in-buffer>

buffer_block_size <bytes-in-block>

HTCondor keeps a buffer of recently-used data for each file a job accesses. This buffer is used both
to cache commonly-used data and to consolidate small reads and writes into larger operations that get
better throughput. The default settings should produce reasonable results for most programs.

These options only apply to standard-universe jobs.

If needed, you may set the buffer controls individually for each file using the buffer_files option.
For example, to set the buffer size to 1 MiB and the block size to 256 KiB for the file input.data,
use this command:

buffer_files = "input.data=(1000000,256000)"

Alternatively, you may use these two options to set the default sizes for all files used by your job:

buffer_size = 1000000
buffer_block_size = 256000

If you do not set these, HTCondor will use the values given by these two configuration file macros:

DEFAULT_IO_BUFFER_SIZE = 1000000
DEFAULT_IO_BUFFER_BLOCK_SIZE = 256000

Finally, if no other settings are present, HTCondor will use a buffer of 512 KiB and a block size of
32 KiB.

compress_files = file1, file2, ...

If your job attempts to access any of the files mentioned in this list, HTCondor will automatically
compress them (if writing) or decompress them (if reading). The compress format is the same as used by
GNU gzip.

The files given in this list may be simple file names or complete paths and may include as a wild
card. For example, this list causes the file /tmp/data.gz, any file named event.gz, and any file
ending in .gzip to be automatically compressed or decompressed as needed:

compress_files = /tmp/data.gz, event.gz, *.gzip

Due to the nature of the compression format, compressed files must only be accessed sequentially.
Random access reading is allowed but is very slow, while random access writing is simply not possible.
This restriction may be avoided by using both compress_files and fetch_files at the same time. When
this is done, a file is kept in the decompressed state at the execution machine, but is compressed for
transfer to its original location.

This option only applies to standard universe jobs.

fetch_files = file1, file2, ...

If your job attempts to access a file mentioned in this list, HTCondor will automatically copy the
whole file to the executing machine, where it can be accessed quickly. When your job closes the file,
it will be copied back to its original location. This list uses the same syntax as compress_files,
shown above.

This option only applies to standard universe jobs.

file_remaps < &ldquo; name newname ; name2 newname2 ... &rdquo;>

Directs HTCondor to use a new file name in place of an old one. namedescribes a file name that your
job may attempt to open, and newnamedescribes the file name it should be replaced with. newnamemay
include an optional leading access specifier, local: or remote: . If left unspecified, the default
access specifier is remote: . Multiple remaps can be specified by separating each with a semicolon.

This option only applies to standard universe jobs.

If you wish to remap file names that contain equals signs or semicolons, these special characters may
be escaped with a backslash.

Example One:

Suppose that your job reads a file named dataset.1. To instruct HTCondor to force your job to read
other.datasetinstead, add this to the submit file:

file_remaps = "dataset.1=other.dataset"

Example Two:

Suppose that your run many jobs which all read in the same large file, called very.big. If this
file can be found in the same place on a local disk in every machine in the pool, (say
/bigdisk/bigfile,) you can instruct HTCondor of this fact by remapping very.bigto
/bigdisk/bigfileand specifying that the file is to be read locally, which will be much faster than
reading over the network.

file_remaps = "very.big = local:/bigdisk/bigfile"

Example Three:

Several remaps can be applied at once by separating each with a semicolon.

file_remaps = "very.big = local:/bigdisk/bigfile ; dataset.1 = other.dataset"

local_files = file1, file2, ...

If your job attempts to access a file mentioned in this list, HTCondor will cause it to be read or
written at the execution machine. This is most useful for temporary files not used for input or
output. This list uses the same syntax as compress_files, shown above.

local_files = /tmp/*

This option only applies to standard universe jobs.

want_remote_io = <True |False>

This option controls how a file is opened and manipulated in a standard universe job. If this option
is true, which is the default, then the condor_shadowmakes all decisions about how each and every file
should be opened by the executing job. This entails a network round trip (or more) from the job to the
condor_shadowand back again for every single open()in addition to other needed information about the
file. If set to false, then when the job queries the condor_shadowfor the first time about how to open
a file, the condor_shadowwill inform the job to automatically perform all of its file manipulation on
the local file system on the execute machine and any file remapping will be ignored. This means that
there mustbe a shared file system (such as NFS or AFS) between the execute machine and the submit
machine and that ALLpaths that the job could open on the execute machine must be valid. The ability of
the standard universe job to checkpoint, possibly to a checkpoint server, is not affected by this
attribute. However, when the job resumes it will be expecting the same file system conditions that
were present when the job checkpointed.

COMMANDS FOR THE GRID

batch_queue = <queuename>

Used for pbs, lsf, and sgegrid universe jobs. Specifies the name of the PBS/LSF/SGE job queue into
which the job should be submitted. If not specified, the default queue is used.

boinc_authenticator_file = <pathname>

For grid type boincjobs, specifies a path and file name of the authorization file that grants
permission for HTCondor to use the BOINC service. There is no default value when not specified.

cream_attributes = <name=value;...;name=value>

Provides a list of attribute/value pairs to be set in a CREAM job description of a grid universe job
destined for the CREAM grid system. The pairs are separated by semicolons, and written in New ClassAd
syntax.

delegate_job_GSI_credentials_lifetime = <seconds>

Specifies the maximum number of seconds for which delegated proxies should be valid. The default
behavior when this command is not specified is determined by the configuration variable
DELEGATE_JOB_GSI_CREDENTIALS_LIFETIME, which defaults to one day. A value of 0 indicates that the
delegated proxy should be valid for as long as allowed by the credential used to create the proxy.
This setting currently only applies to proxies delegated for non-grid jobs and for HTCondor-C jobs. It
does not currently apply to globus grid jobs, which always behave as though this setting were 0. This
variable has no effect if the configuration variable DELEGATE_JOB_GSI_CREDENTIALSis False, because in
that case the job proxy is copied rather than delegated.

ec2_access_key_id = <pathname>

For grid type ec2jobs, identifies the file containing the access key.

ec2_ami_id = <EC2 xMI ID>

For grid type ec2jobs, identifies the machine image. Services compatible with the EC2 Query API may
refer to these with abbreviations other than AMI, for example EMIis valid for Eucalyptus.

ec2_availability_zone = <zone name>

For grid type ec2jobs, specifies the Availability Zone that the instance should be run in. This
command is optional, unless ec2_ebs_volumesis set. As an example, one current zone is us-east-1b.

ec2_block_device_mapping = <block-device>:<kernel-device>,<block-device>:<kernel-device>, ...

For grid type ec2jobs, specifies the block device to kernel device mapping. This command is optional.

ec2_ebs_volumes = <ebs name>:<device name>,<ebs name>:<device name>,...

For grid type ec2jobs, optionally specifies a list of Elastic Block Store (EBS) volumes to be made
available to the instance and the device names they should have in the instance.

ec2_elastic_ip = <elastic IP address>

For grid type ec2jobs, and optional specification of an Elastic IP address that should be assigned to
this instance.

For grid type ec2jobs, a name identifying which Identity and Access Management (IAM) (instance)
profile to associate with the instance.

ec2_instance_type = <instance type>

For grid type ec2jobs, identifies the instance type. Different services may offer different instance
types, so no default value is set.

For grid type ec2jobs, specifies the name of an SSH key-pair that is already registered with the EC2
service. The associated private key can be used to sshinto the virtual machine once it is running.

ec2_keypair_file = <pathname>

For grid type ec2jobs, specifies the complete path and file name of a file into which HTCondor will
write an SSH key for use with ec2 jobs. The key can be used to sshinto the virtual machine once it is
running. If ec2_keypairis specified for a job, ec2_keypair_fileis ignored.

ec2_parameter_names = ParameterName1, ParameterName2, ...

For grid type ec2jobs, a space or comma separated list of the names of additional parameters to pass
when instantiating an instance.

ec2_parameter_<name> = <value>

For grid type ec2jobs, specifies the value for the correspondingly named (instance instantiation)
parameter. <name>is the parameter name specified in the submit command ec2_parameter_names, but with

job.

ec2_spot_price = <bid>

For grid type ec2jobs, specifies the spot instance bid, which is the most that the job submitter is
willing to pay per hour to run this job.

ec2_tag_names = <name0,name1,name...>

For grid type ec2jobs, specifies the case of tag names that will be associated with the running
instance. This is only necessary if a tag name case matters. By default the list will be automatically
generated.

ec2_tag_<name> = <value>

For grid type ec2jobs, specifies a tag to be associated with the running instance. The tag name will
be lower-cased, use ec2_tag_namesto change the case.

WantNameTag = <True |False>

For grid type ec2jobs, a job may request that its 'name' tag be (not) set by HTCondor. If the job does
not otherwise specify any tags, not setting its name tag will eliminate a call by the EC2 GAHP,
improving performance.

ec2_user_data = <data>

For grid type ec2jobs, provides a block of data that can be accessed by the virtual machine. If both
ec2_user_dataand ec2_user_data_fileare specified for a job, the two blocks of data are concatenated,
with the data from this ec2_user_datasubmit command occurring first.

ec2_user_data_file = <pathname>

For grid type ec2jobs, specifies a path and file name whose contents can be accessed by the virtual
machine. If both ec2_user_dataand ec2_user_data_fileare specified for a job, the two blocks of data

virtual machine instance is to run on.

gce_metadata = <name=value,...,name=value>

For grid type gcejobs, a comma separated list of name and value pairs that define metadata for a
virtual machine instance that is an HTCondor job.

gce_metadata_file = <pathname>

For grid type gcejobs, specifies a path and file name of the file that contains metadata for a virtual
machine instance that is an HTCondor job. Within the file, each name and value pair is on its own
line; so, the pairs are separated by the newline character.

gce_preemptible = <True |False>

For grid type gcejobs, specifies whether the virtual machine instance should be preemptible. The
default is for the instance to not be preemptible.

globus_rematch = <ClassAd Boolean Expression>

This expression is evaluated by the condor_gridmanagerwhenever:

1. the globus_resubmitexpression evaluates to True

2. the condor_gridmanagerdecides it needs to retry a submission (as when a previous submission
failed to commit) If globus_rematchevaluates to True, then beforethe job is submitted again to
globus, the condor_gridmanagerwill request that the condor_schedddaemon renegotiate with the
matchmaker (the condor_negotiator). The result is this job will be matched again.

globus_resubmit = <ClassAd Boolean Expression>

The expression is evaluated by the condor_gridmanagereach time the condor_gridmanagergets a job ad to
manage. Therefore, the expression is evaluated:

1. when a grid universe job is first submitted to HTCondor-G

2. when a grid universe job is released from the hold state

3. when HTCondor-G is restarted (specifically, whenever the condor_gridmanageris restarted) If the
expression evaluates to True, then any previous submission to the grid universe will be forgotten
and this job will be submitted again as a fresh submission to the grid universe. This may be useful
if there is a desire to give up on a previous submission and try again. Note that this may result
in the same job running more than once. Do not treat this operation lightly.

globus_rsl = <RSL-string>

Used to provide any additional Globus RSL string attributes which are not covered by other submit
description file commands or job attributes. Used for griduniversejobs, where the grid resource has a
grid-type-stringof gt2.

grid_resource = <grid-type-string> <grid-specific-parameter-list>

For each grid-type-stringvalue, there are further type-specific values that must specified. This
submit description file command allows each to be given in a space-separated list. Allowable grid-
type-stringvalues are batch, condor, cream, ec2, gt2, gt5, lsf, nordugrid, pbs, sge, and unicore. The
HTCondor manual chapter on Grid Computing details the variety of grid types.

For a grid-type-stringof batch, the single parameter is the name of the local batch system, and will
be one of pbs, lsf, or sge.

For a grid-type-stringof condor, the first parameter is the name of the remote condor_schedddaemon.
The second parameter is the name of the pool to which the remote condor_schedddaemon belongs.

For a grid-type-stringof cream, there are three parameters. The first parameter is the web services
address of the CREAM server. The second parameter is the name of the batch system that sits behind the
CREAM server. The third parameter identifies a site-specific queue within the batch system.

For a grid-type-stringof ec2, one additional parameter specifies the EC2 URL.

For a grid-type-stringof gt2, the single parameter is the name of the pre-WS GRAM resource to be used.

For a grid-type-stringof gt5, the single parameter is the name of the pre-WS GRAM resource to be used,
which is the same as for the grid-type-stringof gt2.

For a grid-type-stringof lsf, no additional parameters are used.

For a grid-type-stringof nordugrid, the single parameter is the name of the NorduGrid resource to be
used.

For a grid-type-stringof pbs, no additional parameters are used.

For a grid-type-stringof sge, no additional parameters are used.

For a grid-type-stringof unicore, the first parameter is the name of the Unicore Usite to be used. The
second parameter is the name of the Unicore Vsite to be used.

keystore_alias = <name>

A string to locate the certificate in a Java keystore file, as used for a unicorejob.

keystore_file = <pathname>

The complete path and file name of the Java keystore file containing the certificate to be used for a
unicorejob.

keystore_passphrase_file = <pathname>

The complete path and file name to the file containing the passphrase protecting a Java keystore file
containing the certificate. Relevant for a unicorejob.

MyProxyCredentialName = <symbolic name>

The symbolic name that identifies a credential to the MyProxyserver. This symbolic name is set as the
credential is initially stored on the server (using myproxy-init).

MyProxyHost = <host>:<port>

The Internet address of the host that is the MyProxyserver. The hostmay be specified by either a host
name (as in head.example.com) or an IP address (of the form 123.456.7.8). The portnumber is an
integer.

MyProxyNewProxyLifetime = <number-of-minutes>

The new lifetime (in minutes) of the proxy after it is refreshed.

MyProxyPassword = <password>

The password needed to refresh a credential on the MyProxyserver. This password is set when the user
initially stores credentials on the server (using myproxy-init). As an alternative to using
MyProxyPasswordin the submit description file, the password may be specified as a command line
argument to condor_submit with the -passwordargument.

MyProxyRefreshThreshold = <number-of-seconds>

The time (in seconds) before the expiration of a proxy that the proxy should be refreshed. For
example, if MyProxyRefreshThresholdis set to the value 600, the proxy will be refreshed 10 minutes
before it expires.

MyProxyServerDN = <credential subject>

A string that specifies the expected Distinguished Name (credential subject, abbreviated DN) of the
MyProxyserver. It must be specified when the MyProxyserver DN does not follow the conventional naming
scheme of a host credential. This occurs, for example, when the MyProxyserver DN begins with a user
credential.

nordugrid_rsl = <RSL-string>

Used to provide any additional RSL string attributes which are not covered by regular submit
description file parameters. Used when the universeis grid, and the type of grid system is nordugrid.

transfer_error = <True |False>

For jobs submitted to the grid universe only. If True, then the error output (from stderr) from the
job is transferred from the remote machine back to the submit machine. The name of the file after
transfer is given by the errorcommand. If False, no transfer takes place (from the remote machine to
submit machine), and the name of the file is given by the errorcommand. The default value is True.

transfer_input = <True |False>

For jobs submitted to the grid universe only. If True, then the job input (stdin) is transferred from
the machine where the job was submitted to the remote machine. The name of the file that is
transferred is given by the inputcommand. If False, then the job's input is taken from a pre-staged
file on the remote machine, and the name of the file is given by the inputcommand. The default value
is True.

For transferring files other than stdin, see transfer_input_files.

transfer_output = <True |False>

For jobs submitted to the grid universe only. If True, then the output (from stdout) from the job is
transferred from the remote machine back to the submit machine. The name of the file after transfer is
given by the outputcommand. If False, no transfer takes place (from the remote machine to submit
machine), and the name of the file is given by the outputcommand. The default value is True.

For transferring files other than stdout, see transfer_output_files.

use_x509userproxy = <True |False>

Set this command to Trueto indicate that the job requires an X.509 user proxy. If x509userproxyis set,
then that file is used for the proxy. Otherwise, the proxy is looked for in the standard locations. If
x509userproxyis set or if the job is a grid universe job of grid type gt2, gt5, cream, or nordugrid,
then the value of use_x509userproxyis forced to True. Defaults to False.

x509userproxy = <full-pathname>

Used to override the default path name for X.509 user certificates. The default location for X.509
proxies is the /tmpdirectory, which is generally a local file system. Setting this value would allow
HTCondor to access the proxy in a shared file system (for example, AFS). HTCondor will use the proxy
specified in the submit description file first. If nothing is specified in the submit description
file, it will use the environment variable X509_USER_PROXY. If that variable is not present, it will
search in the default location. Note that proxies are only valid for a limited time. Condor_submit
will not submit a job with an expired proxy, it will return an error. Also, if the configuration
parameter CRED_MIN_TIME_LEFT is set to some number of seconds, and if the proxy will expire before
that many seconds, condor_submit will also refuse to submit the job. That is, if CRED_MIN_TIME_LEFT
is set to 60, condor_submit will refuse to submit a job whose proxy will expire 60 seconds from the
time of submission.

x509userproxyis relevant when the universeis vanilla, or when the universeis gridand the type of grid
system is one of gt2, gt5, condor, cream, or nordugrid. Defining a value causes the proxy to be
delegated to the execute machine. Further, VOMS attributes defined in the proxy will appear in the job
ClassAd.

COMMANDS FOR PARALLEL, JAVA, and SCHEDULER UNIVERSES

hold_kill_sig = <signal-number>

For the scheduler universe only, signal-numberis the signal delivered to the job when the job is put
on hold with condor_hold. signal-numbermay be either the platform-specific name or value of the
signal. If this command is not present, the value of kill_sigis used.

jar_files = <file_list>

Specifies a list of additional JAR files to include when using the Java universe. JAR files will be
transferred along with the executable and automatically added to the classpath.

java_vm_args = <argument_list>

Specifies a list of additional arguments to the Java VM itself, When HTCondor runs the Java program,
these are the arguments that go before the class name. This can be used to set VM-specific arguments
like stack size, garbage-collector arguments and initial property values.

machine_count = <max>

For the parallel universe, a single value (max) is required. It is neither a maximum or minimum, but
the number of machines to be dedicated toward running the job.

remove_kill_sig = <signal-number>

For the scheduler universe only, signal-numberis the signal delivered to the job when the job is
removed with condor_rm. signal-numbermay be either the platform-specific name or value of the signal.
This example shows it both ways for a Linux signal:

remove_kill_sig = SIGUSR1
remove_kill_sig = 10

If this command is not present, the value of kill_sigis used.

COMMANDS FOR THE VM UNIVERSE

vm_disk = file1:device1:permission1, file2:device2:permission2:format2, ...

A list of comma separated disk files. Each disk file is specified by 4 colon separated fields. The
first field is the path and file name of the disk file. The second field specifies the device. The
third field specifies permissions, and the optional fourth field specifies the image format. If a disk
file will be transferred by HTCondor, then the first field should just be the simple file name (no
path information).

An example that specifies two disk files:

vm_disk = /myxen/diskfile.img:sda1:w,/myxen/swap.img:sda2:w

vm_checkpoint = <True |False>

A boolean value specifying whether or not to take checkpoints. If not specified, the default value is
False. In the current implementation, setting both vm_checkpointand vm_networkingto Truedoes not yet
work in all cases. Networking cannot be used if a vm universe job uses a checkpoint in order to
continue execution after migration to another machine.

vm_macaddr = <MACAddr>

Defines that MAC address that the virtual machine's network interface should have, in the standard
format of six groups of two hexadecimal digits separated by colons.

vm_memory = <MBytes-of-memory>

The amount of memory in MBytes that a vm universe job requires.

vm_networking = <True |False>

Specifies whether to use networking or not. In the current implementation, setting both
vm_checkpointand vm_networkingto Truedoes not yet work in all cases. Networking cannot be used if a vm
universe job uses a checkpoint in order to continue execution after migration to another machine.

vm_networking_type = <nat |bridge >

When vm_networkingis True, this definition augments the job's requirements to match only machines with
the specified networking. If not specified, then either networking type matches.

vm_no_output_vm = <True |False>

When True, prevents HTCondor from transferring output files back to the machine from which the vm
universe job was submitted. If not specified, the default value is False.

vm_type = <vmware |xen |kvm>

Specifies the underlying virtual machine software that this job expects.

vmware_dir = <pathname>

The complete path and name of the directory where VMware-specific files and applications such as the
VMDK (Virtual Machine Disk Format) and VMX (Virtual Machine Configuration) reside. This command is
optional; when not specified, all relevant VMware image files are to be listed using
transfer_input_files.

vmware_should_transfer_files = <True |False>

Specifies whether HTCondor will transfer VMware-specific files located as specified by vmware_dirto
the execute machine (True) or rely on access through a shared file system (False). Omission of this
required command (for VMware vm universe jobs) results in an error message from condor_submit , and
the job will not be submitted.

vmware_snapshot_disk = <True |False>

When True, causes HTCondor to utilize a VMware snapshot disk for new or modified files. If not
specified, the default value is True.

xen_initrd = <image-file>

When xen_kernelgives a file name for the kernel image to use, this optional command may specify a path
to a ramdisk (initrd) image file. If the image file will be transferred by HTCondor, then the value
should just be the simple file name (no path information).

xen_kernel = <included |path-to-kernel>

A value of includedspecifies that the kernel is included in the disk file. If not one of these values,
then the value is a path and file name of the kernel to be used. If a kernel file will be transferred
by HTCondor, then the value should just be the simple file name (no path information).

xen_kernel_params = <string>

A string that is appended to the Xen kernel command line.

xen_root = <string>

A string that is appended to the Xen kernel command line to specify the root device. This string is
required when xen_kernelgives a path to a kernel. Omission for this required case results in an error
message during submission.

COMMANDS FOR THE DOCKER UNIVERSE

docker_image = < image-name >

Defines the name of the Docker image that is the basis for the docker container.

ADVANCED COMMANDS

accounting_group = <accounting-group-name>

Causes jobs to negotiate under the given accounting group. This value is advertised in the job ClassAd
as AcctGroup. The HTCondor Administrator's manual contains more information about accounting groups.

accounting_group_user = <accounting-group-user-name>

Sets the user name associated with the accounting group name for resource usage accounting purposes.
If not set, defaults to the value of the job ClassAd attribute Owner. This value is advertised in the
job ClassAd as AcctGroupUser. If an accounting group has not been set with the
accounting_groupcommand, this command is ignored.

concurrency_limits = <string-list>

A list of resources that this job needs. The resources are presumed to have concurrency limits placed
upon them, thereby limiting the number of concurrent jobs in execution which need the named resource.
Commas and space characters delimit the items in the list. Each item in the list is a string that
identifies the limit, or it is a ClassAd expression that evaluates to a string, and it is evaluated in
the context of machine ClassAd being considered as a match. Each item in the list also may specify a
numerical value identifying the integer number of resources required for the job. The syntax follows
the resource name by a colon character ( : ) and the numerical value. Details on concurrency limits
are in the HTCondor Administrator's manual.

concurrency_limits_expr = <ClassAd String Expression>

A ClassAd expression that represents the list of resources that this job needs after evaluation. The
ClassAd expression may specify machine ClassAd attributes that are evaluated against a matched
machine. After evaluation, the list sets concurrency_limits.

copy_to_spool = <True |False>

If copy_to_spoolis True, then condor_submit copies the executable to the local spool directory before
running it on a remote host. As copying can be quite time consuming and unnecessary, the default value
is Falsefor all job universes other than the standard universe. When False, condor_submit does not
copy the executable to a local spool directory. The default is Truein standard universe, because
resuming execution from a checkpoint can only be guaranteed to work using precisely the same
executable that created the checkpoint.

coresize = <size>

Should the user's program abort and produce a core file, coresizespecifies the maximum size in bytes
of the core file which the user wishes to keep. If coresizeis not specified in the command file, the
system's user resource limit coredumpsizeis used (note that coredumpsizeis not an HTCondor parameter
&ndash; it is an operating system parameter that can be viewed with the limitor ulimitcommand on Unix
and in the Registry on Windows). A value of -1 results in no limits being applied to the core file
size. If HTCondor is running as root, a coresizesetting greater than the system coredumpsizelimit will
override the system setting; if HTCondor is notrunning as root, the system coredumpsizelimit will
override coresize.

cron_day_of_month = <Cron-evaluated Day>

The set of days of the month for which a deferral time applies. The HTCondor User's manual section on
Time Scheduling for Job Execution has further details.

cron_day_of_week = <Cron-evaluated Day>

The set of days of the week for which a deferral time applies. The HTCondor User's manual section on
Time Scheduling for Job Execution has further details.

cron_hour = <Cron-evaluated Hour>

The set of hours of the day for which a deferral time applies. The HTCondor User's manual section on
Time Scheduling for Job Execution has further details.

cron_minute = <Cron-evaluated Minute>

The set of minutes within an hour for which a deferral time applies. The HTCondor User's manual
section on Time Scheduling for Job Execution has further details.

cron_month = <Cron-evaluated Month>

The set of months within a year for which a deferral time applies. The HTCondor User's manual section
on Time Scheduling for Job Execution has further details.

cron_prep_time = <ClassAd Integer Expression>

Analogous to deferral_prep_time. The number of seconds prior to a job's deferral time that the job may
be matched and sent to an execution machine.

cron_window = <ClassAd Integer Expression>

Analogous to the submit command deferral_window. It allows cron jobs that miss their deferral time to
begin execution.

The HTCondor User's manual section on Time Scheduling for Job Execution has further details.

dagman_log = <pathname>

DAGMan inserts this command to specify an event log that it watches to maintain the state of the DAG.
If the logcommand is not specified in the submit file, DAGMan uses the logcommand to specify the event
log.

deferral_prep_time = <ClassAd Integer Expression>

The number of seconds prior to a job's deferral time that the job may be matched and sent to an
execution machine.

The HTCondor User's manual section on Time Scheduling for Job Execution has further details.

deferral_time = <ClassAd Integer Expression>

Allows a job to specify the time at which its execution is to begin, instead of beginning execution as
soon as it arrives at the execution machine. The deferral time is an expression that evaluates to a
Unix Epoch timestamp (the number of seconds elapsed since 00:00:00 on January 1, 1970, Coordinated
Universal Time). Deferral time is evaluated with respect to the execution machine. This option delays
the start of execution, but not the matching and claiming of a machine for the job. If the job is not
available and ready to begin execution at the deferral time, it has missed its deferral time. A job
that misses its deferral time will be put on hold in the queue.

The HTCondor User's manual section on Time Scheduling for Job Execution has further details.

Due to implementation details, a deferral time may not be used for scheduler universe jobs.

deferral_window = <ClassAd Integer Expression>

The deferral window is used in conjunction with the deferral_timecommand to allow jobs that miss their
deferral time to begin execution.

The HTCondor User's manual section on Time Scheduling for Job Execution has further details.

description = <string>

A string that sets the value of the job ClassAd attribute JobDescription. When set, tools which
display the executable such as condor_qwill instead use this string.

email_attributes = <list-of-job-ad-attributes>

A comma-separated list of attributes from the job ClassAd. These attributes and their values will be
included in the e-mail notification of job completion.

image_size = <size>

Advice to HTCondor specifying the maximum virtual image size to which the job will grow during its
execution. HTCondor will then execute the job only on machines which have enough resources, (such as
virtual memory), to support executing the job. If not specified, HTCondor will automatically make a
(reasonably accurate) estimate about the job's size and adjust this estimate as the program runs. If
specified and underestimated, the job may crash due to the inability to acquire more address space;
for example, if malloc()fails. If the image size is overestimated, HTCondor may have difficulty
finding machines which have the required resources. sizeis specified in KiB. For example, for an image
size of 8 MiB, sizeshould be 8000.

initialdir = <directory-path>

Used to give jobs a directory with respect to file input and output. Also provides a directory (on the
machine from which the job is submitted) for the job event log, when a full path is not specified.

For vanilla universe jobs where there is a shared file system, it is the current working directory on
the machine where the job is executed.

For vanilla or grid universe jobs where file transfer mechanisms are utilized (there is nota shared
file system), it is the directory on the machine from which the job is submitted where the input files
come from, and where the job's output files go to.

For standard universe jobs, it is the directory on the machine from which the job is submitted where
the condor_shadowdaemon runs; the current working directory for file input and output accomplished
through remote system calls.

For scheduler universe jobs, it is the directory on the machine from which the job is submitted where
the job runs; the current working directory for file input and output with respect to relative path
names.

Note that the path to the executable is notrelative to initialdir; if it is a relative path, it is
relative to the directory in which the condor_submit command is run.

job_ad_information_attrs = <attribute-list>

A comma-separated list of job ClassAd attribute names. The named attributes and their values are
written to the job event log whenever any event is being written to the log. This implements the same
thing as the configuration variable EVENT_LOG_INFORMATION_ATTRS(see page ), but it applies to the job
event log, instead of the system event log.

JobBatchName = <batch_name>

Set the batch name for this submit. The batch name is displayed by condor_q-batch. It is intended for
use by users to give meaningful names to their jobs and to influence how condor_qgroups jobs for
display. This value in a submit file can be overridden by specifying the -batch-nameargument on the
condor_submit command line.

job_lease_duration = <number-of-seconds>

For vanilla, parallel, VM, and java universe jobs only, the duration in seconds of a job lease. The
default value is 2,400, or forty minutes. If a job lease is not desired, the value can be explicitly
set to 0 to disable the job lease semantics. The value can also be a ClassAd expression that evaluates
to an integer. The HTCondor User's manual section on Special Environment Considerations has further
details.

job_machine_attrs = <attr1, attr2, ...>

A comma and/or space separated list of machine attribute names that should be recorded in the job
ClassAd in addition to the ones specified by the condor_schedddaemon's system configuration variable
SYSTEM_JOB_MACHINE_ATTRS. When there are multiple run attempts, history of machine attributes from
previous run attempts may be kept. The number of run attempts to store may be extended beyond the
system-specified history length by using the submit file command job_machine_attrs_history_length. A
machine attribute named Xwill be inserted into the job ClassAd as an attribute named MachineAttrX0.
The previous value of this attribute will be named MachineAttrX1, the previous to that will be named
MachineAttrX2, and so on, up to the specified history length. A history of length 1 means that only
MachineAttrX0will be recorded. The value recorded in the job ClassAd is the evaluation of the machine
attribute in the context of the job ClassAd when the condor_schedddaemon initiates the start up of the
job. If the evaluation results in an Undefinedor Errorresult, the value recorded in the job ad will be
Undefinedor Error, respectively.

want_graceful_removal = <boolean expression>

When True, this causes a graceful shutdown of the job when the job is removed or put on hold, giving
it time to clean up or save state. Otherwise, the job is abruptly killed. The default is false.

kill_sig = <signal-number>

When HTCondor needs to kick a job off of a machine, it will send the job the signal specified by
signal-number. signal-numberneeds to be an integer which represents a valid signal on the execution
machine. For jobs submitted to the standard universe, the default value is the number for SIGTSTP
which tells the HTCondor libraries to initiate a checkpoint of the process. For jobs submitted to
other universes, the default value, when not defined, is SIGTERM , which is the standard way to
terminate a program in Unix.

kill_sig_timeout = <seconds>

This submit command should no longer be used as of HTCondor version 7.7.3; use
job_max_vacate_timeinstead. If job_max_vacate_timeis not defined, this defines the number of seconds
that HTCondor should wait following the sending of the kill signal defined by kill_sigand forcibly
killing the job. The actual amount of time between sending the signal and forcibly killing the job is
the smallest of this value and the configuration variable KILLING_TIMEOUT, as defined on the execute
machine.

load_profile = <True |False>

When True, loads the account profile of the dedicated run account for Windows jobs. May not be used
with run_as_owner.

match_list_length = <integer value>

Defaults to the value zero (0). When match_list_lengthis defined with an integer value greater than
zero (0), attributes are inserted into the job ClassAd. The maximum number of attributes defined is
given by the integer value. The job ClassAds introduced are given as

LastMatchName0 = "most-recent-Name"
LastMatchName1 = "next-most-recent-Name"

The value for each introduced ClassAd is given by the value of the Nameattribute from the machine
ClassAd of a previous execution (match). As a job is matched, the definitions for these attributes
will roll, with LastMatchName1 becoming LastMatchName2 , LastMatchName0 becoming LastMatchName1 ,
and LastMatchName0 being set by the most recent value of the Nameattribute.

An intended use of these job attributes is in the requirements expression. The requirements can allow
a job to prefer a match with either the same or a different resource than a previous match.

job_max_vacate_time = <integer expression>

An integer-valued expression (in seconds) that may be used to adjust the time given to an evicted job
for gracefully shutting down. If the job's setting is less than the machine's, the job's is used. If
the job's setting is larger than the machine's, the result depends on whether the job has any excess
retirement time. If the job has more retirement time left than the machine's max vacate time setting,
then retirement time will be converted into vacating time, up to the amount requested by the job.

Setting this expression does not affect the job's resource requirements or preferences. For a job to
only run on a machine with a minimum MachineMaxVacateTime, or to preferentially run on such machines,
explicitly specify this in the requirements and/or rank expressions.

max_job_retirement_time = <integer expression>

An integer-valued expression (in seconds) that does nothing unless the machine that runs the job has
been configured to provide retirement time. Retirement time is a grace period given to a job to finish
when a resource claim is about to be preempted. The default behavior in many cases is to take as much
retirement time as the machine offers, so this command will rarely appear in a submit description
file.

When a resource claim is to be preempted, this expression in the submit file specifies the maximum run
time of the job (in seconds, since the job started). This expression has no effect, if it is greater
than the maximum retirement time provided by the machine policy. If the resource claim is
notpreempted, this expression and the machine retirement policy are irrelevant. If the resource claim
ispreempted the job will be allowed to run until the retirement time expires, at which point it is
hard-killed. The job will be soft-killed when it is getting close to the end of retirement in order to
give it time to gracefully shut down. The amount of lead-time for soft-killing is determined by the
maximum vacating time granted to the job.

Standard universe jobs and any jobs running with nice_userpriority have a default
max_job_retirement_timeof 0, so no retirement time is utilized by default. In all other cases, no
default value is provided, so the maximum amount of retirement time is utilized by default.

Setting this expression does not affect the job's resource requirements or preferences. For a job to
only run on a machine with a minimum MaxJobRetirementTime, or to preferentially run on such machines,
explicitly specify this in the requirements and/or rank expressions.

nice_user = <True |False>

Normally, when a machine becomes available to HTCondor, HTCondor decides which job to run based upon
user and job priorities. Setting nice_userequal to Truetells HTCondor not to use your regular user
priority, but that this job should have last priority among all users and all jobs. So jobs submitted
in this fashion run only on machines which no other non-nice_user job wants &mdash; a true bottom-
feeder job! This is very handy if a user has some jobs they wish to run, but do not wish to use
resources that could instead be used to run other people's HTCondor jobs. Jobs submitted in this
fashion have "nice-user."prepended to the owner name when viewed from condor_qor condor_userprio. The
default value is False.

noop_job = <ClassAd Boolean Expression>

When this boolean expression is True, the job is immediately removed from the queue, and HTCondor
makes no attempt at running the job. The log file for the job will show a job submitted event and a
job terminated event, along with an exit code of 0, unless the user specifies a different signal or
exit code.

noop_job_exit_code = <return value>

When noop_jobis in the submit description file and evaluates to True, this command allows the job to
specify the return value as shown in the job's log file job terminated event. If not specified, the
job will show as having terminated with status 0. This overrides any value specified with
noop_job_exit_signal.

noop_job_exit_signal = <signal number>

When noop_jobis in the submit description file and evaluates to True, this command allows the job to
specify the signal number that the job's log event will show the job having terminated with.

remote_initialdir = <directory-path>

The path specifies the directory in which the job is to be executed on the remote machine. This is
currently supported in all universes except for the standard universe.

rendezvousdir = <directory-path>

Used to specify the shared file system directory to be used for file system authentication when
submitting to a remote scheduler. Should be a path to a preexisting directory.

run_as_owner = <True |False>

A boolean value that causes the job to be run under the login of the submitter, if supported by the
joint configuration of the submit and execute machines. On Unix platforms, this defaults to True, and
on Windows platforms, it defaults to False. May not be used with load_profile. See the HTCondor manual
Platform-Specific Information chapter for administrative details on configuring Windows to support
this option.

stack_size = <size in bytes>

This command applies only to Linux platform jobs that are not standard universe jobs. An integer
number of bytes, representing the amount of stack space to be allocated for the job. This value
replaces the default allocation of stack space, which is unlimited in size.

submit_event_notes = <note>

A string that is appended to the submit event in the job's log file. For DAGMan jobs, the string DAG
Node:and the node's name is automatically defined for submit_event_notes, causing the logged submit
event to identify the DAG node job submitted.

+<attribute> = <value>

A line that begins with a '+' (plus) character instructs condor_submit to insert the given
attributeinto the job ClassAd with the given value. Note that setting an attribute should not be used
in place of one of the specific commands listed above. Often, the command name does not directly
correspond to an attribute name; furthermore, many submit commands result in actions more complex than
simply setting an attribute or attributes. See for a list of HTCondor job attributes.

PRE AND POST SCRIPTS IMPLEMENTED WITH SPECIALLY-NAMED ATTRIBUTES

+PreCmd = <executable>

A vanilla universe job may specify that a script is to be run on the execute machine before the job,
and this is called a prescript. Definition of this specifically-named attribute causes the script,
identified by path and file name, to be executed. The prescript could prepare or initialize the job.
Note that this definition of a prescript is different from the PRE script described in DAGMan. The
prescript is not automatically transferred with the job, as the main executable is, so it must be
entered into the transfer_input_fileslist, when file transfer is enabled.

+PreArgs = <argument_list>

Defines command line arguments for the prescript, presuming the Old argument syntax.

+PreArguments = <argument_list>

Defines command line arguments for the prescript, presuming the New argument syntax. An exception to
the syntax is that double quotes must be escaped with a backslash instead of another double quote.

Note that if both +PreArgs and +PreArguments are specified, the +PreArguments value is used and the
+PreArgs value is ignored.

+PreEnv = <environment_vars>

Defines the environment for the prescript, presuming the Old environment syntax.

+PreEnvironment = <environment_vars>

Defines the environment for the prescript, presuming the New environment syntax.

Note that if both +PreEnv and +PreEnvironment are specified, the +PreEnvironment value is used and the
+PreEnv value is ignored.

+PostCmd = <executable>

A vanilla universe job may specify that a script is to be run on the execute machine after the job
exits, and this is called a postscript. Definition of this specifically-named attribute causes the
script, identified by path and file name, to be executed. The postscript is run if the job exits, but
not if the job is evicted. Note that this definition of a postscript is different from the POST script
described in DAGMan. The postscript is not automatically transferred with the job, as the main
executable is, so it must be entered into the transfer_input_fileslist, when file transfer is enabled.

+PostArgs = <argument_list>

Defines command line arguments for the postscript, presuming the Old argument syntax.

+PostArguments = <argument_list>

Defines command line arguments for the postscript, presuming the New argument syntax. An exception to
the syntax is that double quotes must be escaped with a backslash instead of another double quote
mark.

Note that if both +PostArgs and +PostArguments are specified, the +PostArguments value is used and the
+PostArgs value is ignored.

+PostEnv = <environment_vars>

Defines the environment for the postscript, presuming the Old environment syntax.

+PostEnvironment = <environment_vars>

Defines the environment for the postscript, presuming the New environment syntax.

Note that if both +PostEnv and +PostEnvironment are specified, the +PostEnvironment value is used and
the +PostEnv value is ignored.

If any of the prescript or postscript values are not enclosed in double quotes, they are silently
ignored.

Below is an example of the use of starter pre and post scripts:

+PreCmd = "my_pre"
+PreArgs = "pre\"arg1 prea'rg2"
+PreEnv = "one=1;two=\"2\""
+PostCmd = "my_post"
+PostArguments = "post\"arg1 'post&rdquo;ar g2'"
+PostEnvironment = "one=1 two=\"2\""

For this example PreArgsgenerates a first argument of pre"a1" and a second argument of pre'a2 .
PostArgumentsgenerates a first argument of post"a1 and a second argument of post'a 2 .

MACROS AND COMMENTS

In addition to commands, the submit description file can contain macros and comments.

Macros

Parameterless macros in the form of $(macro_name:default initial value)may be used anywhere in
HTCondor submit description files to provide textual substitution at submit time. Macros can be
defined by lines in the form of

<macro_name> = <string>

Two pre-defined macros are supplied by the submit description file parser. The $(Cluster)or
$(ClusterId)macro supplies the value of the ClusterIdjob ClassAd attribute, and the $(Process)or
$(ProcId)macro supplies the value of the ProcIdjob ClassAd attribute. These macros are intended to aid
in the specification of input/output files, arguments, etc., for clusters with lots of jobs, and/or
could be used to supply an HTCondor process with its own cluster and process numbers on the command
line.

The $(Node)macro is defined for parallel universe jobs, and is especially relevant for MPI
applications. It is a unique value assigned for the duration of the job that essentially identifies
the machine (slot) on which a program is executing. Values assigned start at 0 and increase
monotonically. The values are assigned as the parallel job is about to start.

Recursive definition of macros is permitted. An example of a construction that works is the following:

foo = bar
foo = snap $(foo)

As a result, foo = snap bar.

Note that both left- and right- recursion works, so

foo = bar
foo = $(foo) snap

has as its result foo = bar snap.

The construction

foo = $(foo) bar

by itself will notwork, as it does not have an initial base case. Mutually recursive constructions
such as:

B = bar
C = $(B)
B = $(C) boo

will notwork, and will fill memory with expansions.

A default value may be specified, for use if the macro has no definition. Consider the example

D = $(E:24)

Where Eis not defined within the submit description file, the default value 24 is used, resulting in

D = 24

This is of limited value, as the scope of macro substitution is the submit description file. Thus,
either the macro is or is not defined within the submit description file. If the macro is defined,
then the default value is useless. If the macro is not defined, then there is no point in using it in
a submit command.

To use the dollar sign character ( $ ) as a literal, without macro expansion, use

$(DOLLAR)

In addition to the normal macro, there is also a special kind of macro called a substitution macrothat
allows the substitution of a machine ClassAd attribute value defined on the resource machine itself
(gotten after a match to the machine has been made) into specific commands within the submit
description file. The substitution macro is of the form:

$$(attribute)

As this form of the substitution macro is only evaluated within the context of the machine ClassAd,
use of a scope resolution prefix TARGET.or MY.is not allowed.

A common use of this form of the substitution macro is for the heterogeneous submission of an
executable:

executable = povray.$$(OpSys).$$(Arch)

Values for the OpSysand Archattributes are substituted at match time for any given resource. This
example allows HTCondor to automatically choose the correct executable for the matched machine.

An extension to the syntax of the substitution macro provides an alternative string to use if the
machine attribute within the substitution macro is undefined. The syntax appears as:

$$(attribute:string_if_attribute_undefined)

An example using this extended syntax provides a path name to a required input file. Since the file
can be placed in different locations on different machines, the file's path name is given as an
argument to the program.

arguments = $$(input_file_path:/usr/foo)

On the machine, if the attribute input_file_pathis not defined, then the path /usr/foois used instead.

A further extension to the syntax of the substitution macro allows the evaluation of a ClassAd
expression to define the value. In this form, the expression may refer to machine attributes by
prefacing them with the TARGET.scope resolution prefix. To place a ClassAd expression into the
substitution macro, square brackets are added to delimit the expression. The syntax appears as:

$$([ClassAd expression])

An example of a job that uses this syntax may be one that wants to know how much memory it can use.
The application cannot detect this itself, as it would potentially use all of the memory on a multi-
slot machine. So the job determines the memory per slot, reducing it by 10% to account for
miscellaneous overhead, and passes this as a command line argument to the application. In the submit
description file will be

arguments = --memory $$([TARGET.Memory * 0.9])

To insert two dollar sign characters ( $$ ) as literals into a ClassAd string, use

$$(DOLLARDOLLAR)

The environment macro, $ENV, allows the evaluation of an environment variable to be used in setting a
submit description file command. The syntax used is

$ENV(variable)

An example submit description file command that uses this functionality evaluates the submitter's home
directory in order to set the path and file name of a log file:

log = $ENV(HOME)/jobs/logfile

The environment variable is evaluated when the submit description file is processed.

The $RANDOM_CHOICE macro allows a random choice to be made from a given list of parameters at
submission time. For an expression, if some randomness needs to be generated, the macro may appear as

$RANDOM_CHOICE(0,1,2,3,4,5,6)

When evaluated, one of the parameters values will be chosen.

Comments

Blank lines and lines beginning with a pound sign ('#') character are ignored by the submit
description file parser.

Submit Variables

While processing the queuecommand in a submit file or from the command line, condor_submitwill set the
values of several automatic submit variables so that they can be referred to by statements in the submit
file. With the exception of Cluster and Process, if these variables are set by the submit file, they will
not be modified during queueprocessing.

ClusterId

Set to the integer value that the ClusterIdattribute that the job ClassAd will have when the job is
submitted. All jobs in a single submit will normally have the same value for the ClusterId. If the
-dry-runargument is specified, The value will be 1.

Cluster

Alternate name for the ClusterId submit variable. Before HTCondor version 8.4 this was the only name.

ProcId

Set to the integer value that the ProcIdattribute of the job ClassAd will have when the job is
submitted. The value will start at 0 and increment by 1 for each job submitted.

Process

Alternate name for the ProcId submit variable. Before HTCondor version 8.4 this was the only name.

Node

For parallel universes, set to the value #pArAlLeLnOdE# or #MpInOdE# depending on the parallel
universe type For other universes it is set to nothing.

Step

Set to the step value as it varies from 0 to N-1 where N is the number provided on the queueargument.
This variable changes at the same rate as ProcId when it changes at all. For submit files that don't
make use of the queue number option, Step will always be 0. For submit files that don't make use of
any of the foreach options, Step and ProcId will always be the same.

ItemIndex

Set to the index within the item list being processed by the various queue foreach options. For submit
files that don't make use of any queue foreach list, ItemIndex will always be 0 For submit files that
make use of a slice to select only some items in a foreach list, ItemIndex will only be set to
selected values.

Row

Alternate name for ItemIndex.

Item

when a queue foreach option is used and no variable list is supplied, this variable will be set to the
value of the current item.

The automatic variables below are set before parsing the submit file, and will not vary during processing
unless the submit file itself sets them.

ARCH

Set to the CPU architecture of the machine running condor_submit . The value will be the same as the
automatic configuration variable of the same name.

OPSYS

Set to the name of the operating system on the machine running condor_submit . The value will be the
same as the automatic configuration variable of the same name.

OPSYSANDVER

Set to the name and major version of the operating system on the machine running condor_submit . The
value will be the same as the automatic configuration variable of the same name.

OPSYSMAJORVER

Set to the major version of the operating system on the machine running condor_submit . The value will
be the same as the automatic configuration variable of the same name.

OPSYSVER

Set to the version of the operating system on the machine running condor_submit . The value will be
the same as the automatic configuration variable of the same name.

SPOOL

Set to the full path of the HTCondor spool directory. The value will be the same as the automatic
configuration variable of the same name.

IsLinux

Set to true if the operating system of the machine running condor_submit is a Linux variant. Set to
false otherwise.

IsWindows

Set to true if the operating system of the machine running condor_submit is a Microsoft Windows
variant. Set to false otherwise.

SUBMIT_FILE

Set to the full pathname of the submit file being processed by condor_submit . If submit statements
are read from standard input, it is set to nothing.

Exit Status

       condor_submitwill exit with a status value of 0 (zero) upon success, and a non-zero value upon failure.

Examples

          first will be given command line arguments of 15and 2000, and it will write  its  standard  output  to
          foo.out1.  The  second  will  be  given  command  line  arguments of 30and 2000, and it will write its
          standard output to foo.out2. Similarly the third will have arguments of 45and 6000, and  it  will  use
          foo.out3for its standard output. Standard error output (if any) from all three programs will appear in
          foo.error.

         periodic_remove = CumulativeSuspensionTime >
                           ((RemoteWallClockTime  -  CumulativeSuspensionTime)  / 2.0) in the submit description
       file causes this to happen.

General Remarks

          * For security reasons, HTCondor will refuse to run any jobs submitted by user root (UID = 0) or by  a
          user  whose  default  group  is  group  wheel  (GID = 0). Jobs submitted by user root or a user with a
          default group of wheel will appear to sit forever in the queue in an idle state.

          * All path names specified in the submit description file must be less than 256 characters in  length,
          and command line arguments must be less than 4096 characters in length; otherwise, condor_submit gives
          a warning message but the jobs will not execute properly.

          *  Somewhat understandably, behavior gets bizarre if the user makes the mistake of requesting multiple
          HTCondor jobs to write to the same file, and/or if the user alters any files that need to be  accessed
          by  an  HTCondor job which is still in the queue. For example, the compressing of data or output files
          before an HTCondor job has completed is a common mistake.

          * To disable checkpointing for Standard Universe jobs, include the line:

            +WantCheckpoint = False

          in the submit description file before the queue command(s).
