NAME

       pbs_job_attributes - pbs job attributes

DESCRIPTION

A batch job has the following public attributes shown in the following list. The
attributes marked with the section symbol § are required by POSIX 1003.2d: If an attribute
is unset, the indicated default value is assumed.

Account_Name §
Used for accounting on some hosts. Format: string; default value: none, not used.

Checkpoint §
If supported by the server implementation and the host operating system, the
checkpoint attribute determines when checkpointing will be performed by PBS on
behalf of the job. The legal values for checkpoint are described under the qalter
and qsub commands. Format: the strings "n", "s", "c", "c=mmmm"; default value:
"u", which is unspecified.

depend The type of inter-job dependencies specified by the job owner. Format:
"type:jobid[,jobid...]"; default value: no dependencies.

Error_Path §
The final path name for the file containing the job's standard error stream. See
the qsub and qalter command description for more detail. Format:
"[hostname:]pathname"; default value: (job_name).e(job_number).

Execution_Time §
The time after which the job may execute. The time is maintained in seconds since
Epoch. If this time has not yet been reached, the job will not be scheduled for
execution and the job is said to be in wait state. Format:
"[[CCwYY]MMDDhhmm[.ss]"; default value: time 0, no delay.

group_list §
A list of group_names@hosts which determines the group under which the job is run
on a given host. [internal type: array of strings] When a job is to be placed into
execution, the server will select a group name according to the following ordered
set of rules:

1. Select the group name from the list for which the associated host name matches
the name of the execution host.

2. Select the group name which has no associated host name, the wild card name.

3. Use the login group for the user name under which the job will be run.

Format: "group_name[@host][,group_name[@host]...]".

Hold_Types §
The set of holds currently applied to the job. If the set is not null, the job
will not be scheduled for execution and is said to be in the hold state. Note,
the hold state takes precedence over the wait state. Format: string made up of the
letters 'u', 's', 'o'; default value: no hold.

Job_Name §
The name assigned to the job by the qsub or qalter command. Format: string up to
15 characters, first character must be alphabetic; default value: the base name of
the job script or STDIN.

Join_Path §
If the Join_Paths attribute is {TRUE}, then the job's standard error stream will be
merged, inter-mixed, with the job's standard output stream and placed in the file
determined by the Output_Path attribute. The Error_Path attribute is maintained,
but ignored. Format: boolean, values accepted are "True", "TRUE", "true", "Y",
"y", "1", "False", "FALSE", "false", "N", "n", "0"; default value: false.

Keep_Files §
If Keep_Files contains the values "o" and/or "e" the corresponding streams of the
batch job will be retained on the execution host upon job termination. Keep_Files
overrides the Output_Path and Error_Path attributes. Format: "o", "e", "oe" or
"eo"; default value: no keep, return files to submission host.

Mail_Points §
Identifies at which state changes the server will send mail about the job. Format:
string made up of the letters 'a' for abort, 'b' for beginning, and default value:
'a', send on job abort.

Mail_Users §
The set of users to whom mail may be sent when the job makes certain state changes.
Format: "user@host[,user@host]"; default value: job owner only.

Output_Path §
The final path name for the file containing the job's standard output stream. See
the qsub and qalter command description for more detail. Format: see error_path,
default value: (job_name).o(job_number).

Priority §
The job scheduling priority assigned by the user. Format: "[+|-]nnnnn"; default
value: undefined.

Rerunable §
The rerunable flag given by the user. Format: "y" or "n", see Join_Path; default
value: y, job is rerunable.

Resource_List §
The list of resources required by the job. The resource list is a set of
name=value strings. The meaning of name and value is server dependent. The value
also establishes the limit of usage of that resource. If not set, the value for a
resource may be determined by a queue or server default established by the
administrator. Default value: no usage or no limit depending on specific resource.

Shell_Path_List §
A set of absolute paths of the program to process the job's script file. The list
is in the format: "path[@host][,path[@host]...]". If this is null, then the user's
login shell on the host of execution will be used. Default value: null, login
shell.

stagein
The list of files to be staged in prior to job execution. Format:
local_path@remote_host:remote_path

stageout
The list of files to be staged out after job execution. Format:
local_path@remote_host:remote_path

User_List §
The list of user@hosts which determines the user name under which the job is run on
a given host. [internal type: array of strings] When a job is to be placed into
execution, the server will select a user name from the list according to the
following ordered set of rules:

1. Select the user name from the list for which the associated host name matches
the name of the execution host.

2. Select the user name which has no associated host name, the wild card name.

3. Use the Job_Owner as the user name.

Default value: job owner name.

Variable_List §
This is the list of environment variables passed with the Queue Job batch request.
Format: "name=value[,name=value...]".

The following attributes require system, manager, or operator privilege to set. They are
visible to clients depending on privilege as noted.

comment
An attribute for displaying comments about the job from the system. Visible to any
client. Format: any string; default value: none.

sched_hint
This attribute is present when the job is a member of a synchronous dependency set.
It is set when the hold is released on the job. The value is
{SYNC_SCHED_HINT_FIRST} (1) when the first job of the set is released for
scheduling. This is a hint that may be used by the scheduler to decrease the
priority of the job. This keeps a user from attempting to game the scheduler. The
attribute is set to {SYNC_SCHED_HINT_OTHER} (2) for all other jobs in the set as
they become schedulable. This should be taken as a hint by the scheduler to
increase their priority to insure they will run at the same time as the earlier
scheduled jobs in the set. [This attribute is viewable only by the batch
administrator.] [type: integer]

The following attributes are read-only, they are established by the server and are visible
to the client but cannot be set by a client. Certain ones are only visible to privileged
clients (those run by the batch administrator).

alt_id For a few systems, such as Irix 6.x running Array Services, the session id is
insufficient to track which processes belong to the job. Where a different
identifier is required, it is recorded in this attribute. If set, it will also be
recorded in the end-of-job accounting record.

For Irix 6.x running Array Services, the alt_id attribute is set to the Array
Session Handle (ASH) assigned to the job.

ctime The time that the job was created.

etime The time that the job became eligible to run, i.e. in a queued state while residing
in an execution queue.

exec_host
If the job is running, this is set to the name of the host on which the job is
executing.

exit_status
The exit status of the job. This is only set on receipt of a job obituary notice
from MOM, and probably only useful if the "keep_completed" server attribute is set.
Note that negative values are generated internally by PBS to indicate system errors
and are listed as the JOB_EXEC_* defines in pbs_job.h. Positive values are
returned from the user script and cannot be interpreted by PBS.

egroup If the job is queued in an execution queue, this attribute is set to the group name
under which the job is to be run. [This attribute is available only to the batch
administrator.]

euser If the job is queued in an execution queue, this attribute is set to the user name
under which the job is to be run. [This attribute is available only to the batch
administrator.]

hashname
The name used as a basename for various files, such as the job file, script file,
and the standard output and error of the job. [This attribute is available only to
the batch administrator.]

interactive
True if the job is an interactive PBS job. Format: boolean, see Join_Paths;
default value: false.

Job_Owner §
The login name on the submitting host of the user who submitted the batch job.

job_state
The state of the job.

E for exiting, the job has completed execution, with or without errors, and
the batch system is doing post-execution clean-up.

H for Held, one or more holds have been applied to the job.

Q for Queued, the job resides in a execution or routing queue pending
execution or routing. It is not in held or waiting state.

R for Running, the job resides in a execution queue and has been placed into
execution.

S for Suspend (Job running on Unicos only), the job was executing and has been
suspended. The job retains its assigned resources but does not use cpu
cycle or walltime.

T for Transiting, the job is in process of being routed or moved to a new
destination.

W for Waiting, the job is not held but the Execution_Time attribute contains a
time which has not yet been reached.

mtime The time that the job was last modified, changed state, or changed locations.

qtime The time that the job entered the current queue.

queue The name of the queue in which the job currently resides.

queue_rank
An ordered, non-sequential number indicating the job's position with in the queue.
This is provided as an aid to the scheduler. [This attribute is available to the
batch manager only.]

queue_type
An identification of the the type of queue in which the job is currently residing.
This is provided as an aid to the scheduler. [This attribute is available to the
batch manager only.] Format: The letter E or the letter r.

resources_used §
The amount of resources used by the job. This is provided as part of job status
information if the job is running.

server
The name of the server which is currently managing the job.

session_id
If the job is running, this is set to the session id of the first executing task.

substate
A numerical indicator of the substate of the job. The substate is used by the PBS
job server internally. The attribute is visible to privileged clients, such as
the scheduler. Format: integer.
