NAME
sbatch - Submit a batch script to Slurm.
SYNOPSIS
sbatch [OPTIONS(0)...] [ : [OPTIONS(N)...]] script(0) [args(0)...]
Option(s) define multiple jobs in a co-scheduled heterogeneous job. For more details
about heterogeneous jobs see the document
https://slurm.schedmd.com/heterogeneous_jobs.html
DESCRIPTION
sbatch submits a batch script to Slurm. The batch script may be given to sbatch through a
file name on the command line, or if no file name is specified, sbatch will read in a
script from standard input. The batch script may contain options preceded with "#SBATCH"
before any executable commands in the script. sbatch will stop processing further #SBATCH
directives once the first non-comment non-whitespace line has been reached in the script.
sbatch exits immediately after the script is successfully transferred to the Slurm
controller and assigned a Slurm job ID. The batch script is not necessarily granted
resources immediately, it may sit in the queue of pending jobs for some time before its
required resources become available.
By default both standard output and standard error are directed to a file of the name
"slurm-%j.out", where the "%j" is replaced with the job allocation number. The file will
be generated on the first node of the job allocation. Other than the batch script itself,
Slurm does no movement of user files.
When the job allocation is finally granted for the batch script, Slurm runs a single copy
of the batch script on the first node in the set of allocated nodes.
The following document describes the influence of various options on the allocation of
cpus to jobs and tasks.
https://slurm.schedmd.com/cpu_management.html
RETURN VALUE
sbatch will return 0 on success or error code on failure.
SCRIPT PATH RESOLUTION
The batch script is resolved in the following order:
1. If script starts with ".", then path is constructed as: current working directory /
script
2. If script starts with a "/", then path is considered absolute.
3. If script is in current working directory.
4. If script can be resolved through PATH. See path_resolution(7).
Current working directory is the calling process working directory unless the --chdir
argument is passed, which will override the current working directory.
OPTIONS
-a, --array=<indexes>
Submit a job array, multiple jobs to be executed with identical parameters. The
indexes specification identifies what array index values should be used. Multiple
values may be specified using a comma separated list and/or a range of values with
a "-" separator. For example, "--array=0-15" or "--array=0,6,16-32". A step
function can also be specified with a suffix containing a colon and number. For
example, "--array=0-15:4" is equivalent to "--array=0,4,8,12". A maximum number of
simultaneously running tasks from the job array may be specified using a "%"
separator. For example "--array=0-15%4" will limit the number of simultaneously
running tasks from this job array to 4. The minimum index value is 0. the maximum
value is one less than the configuration parameter MaxArraySize. NOTE: currently,
federated job arrays only run on the local cluster.
-A, --account=<account>
Charge resources used by this job to specified account. The account is an
arbitrary string. The account name may be changed after job submission using the
scontrol command.
--acctg-freq
Define the job accounting and profiling sampling intervals. This can be used to
override the JobAcctGatherFrequency parameter in Slurm's configuration file,
slurm.conf. The supported format is as follows:
--acctg-freq=<datatype>=<interval>
where <datatype>=<interval> specifies the task sampling interval for
the jobacct_gather plugin or a sampling interval for a profiling type
by the acct_gather_profile plugin. Multiple, comma-separated
<datatype>=<interval> intervals may be specified. Supported datatypes
are as follows:
task=<interval>
where <interval> is the task sampling interval in seconds for
the jobacct_gather plugins and for task profiling by the
acct_gather_profile plugin. NOTE: This frequency is used to
monitor memory usage. If memory limits are enforced the highest
frequency a user can request is what is configured in the
slurm.conf file. They can not turn it off (=0) either.
energy=<interval>
where <interval> is the sampling interval in seconds for energy
profiling using the acct_gather_energy plugin
network=<interval>
where <interval> is the sampling interval in seconds for
infiniband profiling using the acct_gather_infiniband plugin.
filesystem=<interval>
where <interval> is the sampling interval in seconds for
filesystem profiling using the acct_gather_filesystem plugin.
The default value for the task sampling interval is 30 seconds.
The default value for all other intervals is 0. An interval of 0 disables sampling
of the specified type. If the task sampling interval is 0, accounting information
is collected only at job termination (reducing Slurm interference with the job).
Smaller (non-zero) values have a greater impact upon job performance, but a value
of 30 seconds is not likely to be noticeable for applications having less than
10,000 tasks.
-B --extra-node-info=<sockets[:cores[:threads]]>
Restrict node selection to nodes with at least the specified number of sockets,
cores per socket and/or threads per core. NOTE: These options do not specify the
resource allocation size. Each value specified is considered a minimum. An
asterisk (*) can be used as a placeholder indicating that all available resources
of that type are to be utilized. Values can also be specified as min-max. The
individual levels can also be specified in separate options if desired:
--sockets-per-node=<sockets>
--cores-per-socket=<cores>
--threads-per-core=<threads>
If task/affinity plugin is enabled, then specifying an allocation in this manner
also results in subsequently launched tasks being bound to threads if the -B option
specifies a thread count, otherwise an option of cores if a core count is
specified, otherwise an option of sockets. If SelectType is configured to
select/cons_res, it must have a parameter of CR_Core, CR_Core_Memory, CR_Socket, or
CR_Socket_Memory for this option to be honored. If not specified, the scontrol
show job will display 'ReqS:C:T=*:*:*'. This option applies to job allocations.
--batch=<list>
Nodes can have features assigned to them by the Slurm administrator. Users can
specify which of these features are required by their batch script using this
options. For example a job's allocation may include both Intel Haswell and KNL
nodes with features "haswell" and "knl" respectively. On such a configuration the
batch script would normally benefit by executing on a faster Haswell node. This
would be specified using the option "--batch=haswell". The specification can
include AND and OR operators using the ampersand and vertical bar separators. For
example: "--batch=haswell|broadwell" or "--batch=haswell|big_memory". The --batch
argument must be a subset of the job's --constraint=<list> argument (i.e. the job
can not request only KNL nodes, but require the script to execute on a Haswell
node). If the request can not be satisfied from the resources allocated to the
job, the batch script will execute on the first node of the job allocation.
--bb=<spec>
Burst buffer specification. The form of the specification is system dependent.
Note the burst buffer may not be accessible from a login node, but require that
salloc spawn a shell on one of it's allocated compute nodes. See the description of
SallocDefaultCommand in the slurm.conf man page for more information about how to
spawn a remote shell.
--bbf=<file_name>
Path of file containing burst buffer specification. The form of the specification
is system dependent. These burst buffer directives will be inserted into the
submitted batch script.
-b, --begin=<time>
Submit the batch script to the Slurm controller immediately, like normal, but tell
the controller to defer the allocation of the job until the specified time.
Time may be of the form HH:MM:SS to run a job at a specific time of day (seconds
are optional). (If that time is already past, the next day is assumed.) You may
also specify midnight, noon, fika (3 PM) or teatime (4 PM) and you can have a
time-of-day suffixed with AM or PM for running in the morning or the evening. You
can also say what day the job will be run, by specifying a date of the form MMDDYY
or MM/DD/YY YYYY-MM-DD. Combine date and time using the following format
YYYY-MM-DD[THH:MM[:SS]]. You can also give times like now + count time-units, where
the time-units can be seconds (default), minutes, hours, days, or weeks and you can
tell Slurm to run the job today with the keyword today and to run the job tomorrow
with the keyword tomorrow. The value may be changed after job submission using the
scontrol command. For example:
--begin=16:00
--begin=now+1hour
--begin=now+60 (seconds by default)
--begin=2010-01-20T12:34:00
Notes on date/time specifications:
- Although the 'seconds' field of the HH:MM:SS time specification is allowed by
the code, note that the poll time of the Slurm scheduler is not precise enough to
guarantee dispatch of the job on the exact second. The job will be eligible to
start on the next poll following the specified time. The exact poll interval
depends on the Slurm scheduler (e.g., 60 seconds with the default sched/builtin).
- If no time (HH:MM:SS) is specified, the default is (00:00:00).
- If a date is specified without a year (e.g., MM/DD) then the current year is
assumed, unless the combination of MM/DD and HH:MM:SS has already passed for that
year, in which case the next year is used.
--checkpoint=<time>
Specifies the interval between creating checkpoints of the job step. By default,
the job step will have no checkpoints created. Acceptable time formats include
"minutes", "minutes:seconds", "hours:minutes:seconds", "days-hours",
"days-hours:minutes" and "days-hours:minutes:seconds".
--cluster-constraint=[!]<list>
Specifies features that a federated cluster must have to have a sibling job
submitted to it. Slurm will attempt to submit a sibling job to a cluster if it has
at least one of the specified features. If the "!" option is included, Slurm will
attempt to submit a sibling job to a cluster that has none of the specified
features.
--comment=<string>
An arbitrary comment enclosed in double quotes if using spaces or some special
characters.
-C, --constraint=<list>
Nodes can have features assigned to them by the Slurm administrator. Users can
specify which of these features are required by their job using the constraint
option. Only nodes having features matching the job constraints will be used to
satisfy the request. Multiple constraints may be specified with AND, OR, matching
OR, resource counts, etc. (some operators are not supported on all system types).
Supported constraint options include:
Single Name
Only nodes which have the specified feature will be used. For example,
--constraint="intel"
Node Count
A request can specify the number of nodes needed with some feature by
appending an asterisk and count after the feature name. For example
"--nodes=16 --constraint=graphics*4 ..." indicates that the job requires 16
nodes and that at least four of those nodes must have the feature
"graphics."
AND If only nodes with all of specified features will be used. The ampersand is
used for an AND operator. For example, --constraint="intel&gpu"
OR If only nodes with at least one of specified features will be used. The
vertical bar is used for an OR operator. For example,
--constraint="intel|amd"
Matching OR
If only one of a set of possible options should be used for all allocated
nodes, then use the OR operator and enclose the options within square
brackets. For example: "--constraint=[rack1|rack2|rack3|rack4]" might be
used to specify that all nodes must be allocated on a single rack of the
cluster, but any of those four racks can be used.
Multiple Counts
Specific counts of multiple resources may be specified by using the AND
operator and enclosing the options within square brackets. For example:
"--constraint=[rack1*2&rack2*4]" might be used to specify that two nodes
must be allocated from nodes with the feature of "rack1" and four nodes must
be allocated from nodes with the feature "rack2".
NOTE: This construct does not support multiple Intel KNL NUMA or MCDRAM
modes. For example, while "--constraint=[(knl&quad)*2&(knl&hemi)*4]" is not
supported, "--constraint=[haswell*2&(knl&hemi)*4]" is supported.
Specification of multiple KNL modes requires the use of a heterogeneous job.
Parenthesis
Parenthesis can be used to group like node features together. For example
"--constraint=[(knl&snc4&flat)*4&haswell*1]" might be used to specify that
four nodes with the features "knl", "snc4" and "flat" plus one node with the
feature "haswell" are required. All options within parenthesis should be
grouped with AND (e.g. "&") operands.
--contiguous
If set, then the allocated nodes must form a contiguous set. Not honored with the
topology/tree or topology/3d_torus plugins, both of which can modify the node
ordering.
--cores-per-socket=<cores>
Restrict node selection to nodes with at least the specified number of cores per
socket. See additional information under -B option above when task/affinity plugin
is enabled.
--cpu-freq =<p1[-p2[:p3]]>
Request that job steps initiated by srun commands inside this sbatch script be run
at some requested frequency if possible, on the CPUs selected for the step on the
compute node(s).
p1 can be [#### | low | medium | high | highm1] which will set the frequency
scaling_speed to the corresponding value, and set the frequency scaling_governor to
UserSpace. See below for definition of the values.
p1 can be [Conservative | OnDemand | Performance | PowerSave] which will set the
scaling_governor to the corresponding value. The governor has to be in the list set
by the slurm.conf option CpuFreqGovernors.
When p2 is present, p1 will be the minimum scaling frequency and p2 will be the
maximum scaling frequency.
p2 can be [#### | medium | high | highm1] p2 must be greater than p1.
p3 can be [Conservative | OnDemand | Performance | PowerSave | UserSpace] which
will set the governor to the corresponding value.
If p3 is UserSpace, the frequency scaling_speed will be set by a power or energy
aware scheduling strategy to a value between p1 and p2 that lets the job run within
the site's power goal. The job may be delayed if p1 is higher than a frequency that
allows the job to run within the goal.
If the current frequency is < min, it will be set to min. Likewise, if the current
frequency is > max, it will be set to max.
Acceptable values at present include:
#### frequency in kilohertz
Low the lowest available frequency
High the highest available frequency
HighM1 (high minus one) will select the next highest available frequency
Medium attempts to set a frequency in the middle of the available range
Conservative attempts to use the Conservative CPU governor
OnDemand attempts to use the OnDemand CPU governor (the default value)
Performance attempts to use the Performance CPU governor
PowerSave attempts to use the PowerSave CPU governor
UserSpace attempts to use the UserSpace CPU governor
The following informational environment variable is set in the job
step when --cpu-freq option is requested.
SLURM_CPU_FREQ_REQ
This environment variable can also be used to supply the value for the CPU
frequency request if it is set when the 'srun' command is issued. The --cpu-freq
on the command line will override the environment variable value. The form on the
environment variable is the same as the command line. See the ENVIRONMENT
VARIABLES section for a description of the SLURM_CPU_FREQ_REQ variable.
NOTE: This parameter is treated as a request, not a requirement. If the job step's
node does not support setting the CPU frequency, or the requested value is outside
the bounds of the legal frequencies, an error is logged, but the job step is
allowed to continue.
NOTE: Setting the frequency for just the CPUs of the job step implies that the
tasks are confined to those CPUs. If task confinement (i.e.,
TaskPlugin=task/affinity or TaskPlugin=task/cgroup with the "ConstrainCores"
option) is not configured, this parameter is ignored.
NOTE: When the step completes, the frequency and governor of each selected CPU is
reset to the previous values.
NOTE: When submitting jobs with the --cpu-freq option with linuxproc as the
ProctrackType can cause jobs to run too quickly before Accounting is able to poll
for job information. As a result not all of accounting information will be present.
--cpus-per-gpu=<ncpus>
Advise Slurm that ensuing job steps will require ncpus processors per allocated
GPU. Requires the --gpus option. Not compatible with the --cpus-per-task option.
-c, --cpus-per-task=<ncpus>
Advise the Slurm controller that ensuing job steps will require ncpus number of
processors per task. Without this option, the controller will just try to allocate
one processor per task.
For instance, consider an application that has 4 tasks, each requiring 3
processors. If our cluster is comprised of quad-processors nodes and we simply ask
for 12 processors, the controller might give us only 3 nodes. However, by using
the --cpus-per-task=3 options, the controller knows that each task requires 3
processors on the same node, and the controller will grant an allocation of 4
nodes, one for each of the 4 tasks.
--deadline=<OPT>
remove the job if no ending is possible before this deadline (start > (deadline -
time[-min])). Default is no deadline. Valid time formats are:
HH:MM[:SS] [AM|PM]
MMDD[YY] or MM/DD[/YY] or MM.DD[.YY]
MM/DD[/YY]-HH:MM[:SS]
YYYY-MM-DD[THH:MM[:SS]]]
--delay-boot=<minutes>
Do not reboot nodes in order to satisfied this job's feature specification if the
job has been eligible to run for less than this time period. If the job has waited
for less than the specified period, it will use only nodes which already have the
specified features. The argument is in units of minutes. A default value may be
set by a system administrator using the delay_boot option of the
SchedulerParameters configuration parameter in the slurm.conf file, otherwise the
default value is zero (no delay).
-d, --dependency=<dependency_list>
Defer the start of this job until the specified dependencies have been satisfied
completed. <dependency_list> is of the form
<type:job_id[:job_id][,type:job_id[:job_id]]> or
<type:job_id[:job_id][?type:job_id[:job_id]]>. All dependencies must be satisfied
if the "," separator is used. Any dependency may be satisfied if the "?" separator
is used. Many jobs can share the same dependency and these jobs may even belong to
different users. The value may be changed after job submission using the scontrol
command. Once a job dependency fails due to the termination state of a preceding
job, the dependent job will never be run, even if the preceding job is requeued and
has a different termination state in a subsequent execution.
after:job_id[:jobid...]
This job can begin execution after the specified jobs have begun execution.
afterany:job_id[:jobid...]
This job can begin execution after the specified jobs have terminated.
afterburstbuffer:job_id[:jobid...]
This job can begin execution after the specified jobs have terminated and
any associated burst buffer stage out operations have completed.
aftercorr:job_id[:jobid...]
A task of this job array can begin execution after the corresponding task ID
in the specified job has completed successfully (ran to completion with an
exit code of zero).
afternotok:job_id[:jobid...]
This job can begin execution after the specified jobs have terminated in
some failed state (non-zero exit code, node failure, timed out, etc).
afterok:job_id[:jobid...]
This job can begin execution after the specified jobs have successfully
executed (ran to completion with an exit code of zero).
expand:job_id
Resources allocated to this job should be used to expand the specified job.
The job to expand must share the same QOS (Quality of Service) and
partition. Gang scheduling of resources in the partition is also not
supported.
singleton
This job can begin execution after any previously launched jobs sharing the
same job name and user have terminated. In other words, only one job by
that name and owned by that user can be running or suspended at any point in
time.
-D, --chdir=<directory>
Set the working directory of the batch script to directory before it is executed.
The path can be specified as full path or relative path to the directory where the
command is executed.
-e, --error=<filename pattern>
Instruct Slurm to connect the batch script's standard error directly to the file
name specified in the "filename pattern". By default both standard output and
standard error are directed to the same file. For job arrays, the default file
name is "slurm-%A_%a.out", "%A" is replaced by the job ID and "%a" with the array
index. For other jobs, the default file name is "slurm-%j.out", where the "%j" is
replaced by the job ID. See the filename pattern section below for filename
specification options.
--exclusive[=user|mcs]
The job allocation can not share nodes with other running jobs (or just other users
with the "=user" option or with the "=mcs" option). The default shared/exclusive
behavior depends on system configuration and the partition's OverSubscribe option
takes precedence over the job's option.
--export=<environment variables [ALL] | NONE>
Identify which environment variables from the submission environment are propagated
to the launched application. By default, all are propagated. Multiple environment
variable names should be comma separated. Environment variable names may be
specified to propagate the current value (e.g. "--export=EDITOR") or specific
values may be exported (e.g. "--export=EDITOR=/bin/emacs"). In these two examples,
the propagated environment will only contain the variable EDITOR, along with
SLURM_* environment variables. However, Slurm will then implicitly attempt to load
the user's environment on the node where the script is being executed, as if
--get-user-env was specified. This will happen whenever NONE or environment
variables are specified. If one desires to add to the submission environment
instead of replacing it, have the argument include ALL (e.g.
"--export=ALL,EDITOR=/bin/emacs"). Make sure ALL is specified first, since sbatch
applies the environment from left to right, overwriting as necessary. Environment
variables propagated from the submission environment will always overwrite
environment variables found in the user environment on the node. If one desires no
environment variables be propagated from the submitting machine, use the argument
NONE. Regardless of this setting, the appropriate SLURM_* task environment
variables are always exported to the environment. This option is particularly
important for jobs that are submitted on one cluster and execute on a different
cluster (e.g. with different paths). To avoid steps inheriting environment export
settings (e.g. NONE) from sbatch command, the environment variable SLURM_EXPORT_ENV
should be set to ALL in the job script.
--export-file=<filename | fd>
If a number between 3 and OPEN_MAX is specified as the argument to this option, a
readable file descriptor will be assumed (STDIN and STDOUT are not supported as
valid arguments). Otherwise a filename is assumed. Export environment variables
defined in <filename> or read from <fd> to the job's execution environment. The
content is one or more environment variable definitions of the form NAME=value,
each separated by a null character. This allows the use of special characters in
environment definitions.
-F, --nodefile=<node file>
Much like --nodelist, but the list is contained in a file of name node file. The
node names of the list may also span multiple lines in the file. Duplicate node
names in the file will be ignored. The order of the node names in the list is not
important; the node names will be sorted by Slurm.
--get-user-env[=timeout][mode]
This option will tell sbatch to retrieve the login environment variables for the
user specified in the --uid option. The environment variables are retrieved by
running something of this sort "su - <username> -c /usr/bin/env" and parsing the
output. Be aware that any environment variables already set in sbatch's
environment will take precedence over any environment variables in the user's login
environment. Clear any environment variables before calling sbatch that you do not
want propagated to the spawned program. The optional timeout value is in seconds.
Default value is 8 seconds. The optional mode value control the "su" options.
With a mode value of "S", "su" is executed without the "-" option. With a mode
value of "L", "su" is executed with the "-" option, replicating the login
environment. If mode not specified, the mode established at Slurm build time is
used. Example of use include "--get-user-env", "--get-user-env=10"
"--get-user-env=10L", and "--get-user-env=S". This option was originally created
for use by Moab.
--gid=<group>
If sbatch is run as root, and the --gid option is used, submit the job with group's
group access permissions. group may be the group name or the numerical group ID.
-G, --gpus=[<type>:]<number>
Specify the total number of GPUs required for the job. An optional GPU type
specification can be supplied. For example "--gpus=volta:3". Multiple options can
be requested in a comma separated list, for example: "--gpus=volta:3,kepler:1".
See also the --gpus-per-node, --gpus-per-socket and --gpus-per-task options.
--gpu-bind=<type>
Bind tasks to specific GPUs. By default every spawned task can access every GPU
allocated to the job.
Supported type options:
closest Bind each task to the GPU(s) which are closest. In a NUMA environment,
each task may be bound to more than one GPU (i.e. all GPUs in that NUMA
environment).
map_gpu:<list>
Bind by setting GPU masks on tasks (or ranks) as specified where <list>
is <gpu_id_for_task_0>,<gpu_id_for_task_1>,... GPU IDs are interpreted as
decimal values unless they are preceded with '0x' in which case they
interpreted as hexadecimal values. If the number of tasks (or ranks)
exceeds the number of elements in this list, elements in the list will be
reused as needed starting from the beginning of the list. To simplify
support for large task counts, the lists may follow a map with an
asterisk and repetition count. For example "map_gpu:0*4,1*4". Not
supported unless the entire node is allocated to the job.
mask_gpu:<list>
Bind by setting GPU masks on tasks (or ranks) as specified where <list>
is <gpu_mask_for_task_0>,<gpu_mask_for_task_1>,... The mapping is
specified for a node and identical mapping is applied to the tasks on
every node (i.e. the lowest task ID on each node is mapped to the first
mask specified in the list, etc.). GPU masks are always interpreted as
hexadecimal values but can be preceded with an optional '0x'. Not
supported unless the entire node is allocated to the job. To simplify
support for large task counts, the lists may follow a map with an
asterisk and repetition count. For example "mask_gpu:0x0f*4,0xf0*4".
Not supported unless the entire node is allocated to the job.
--gpu-freq=[<type]=value>[,<type=value>][,verbose]
Request that GPUs allocated to the job are configured with specific frequency
values. This option can be used to independently configure the GPU and its memory
frequencies. After the job is completed, the frequencies of all affected GPUs will
be reset to the highest possible values. In some cases, system power caps may
override the requested values. The field type can be "memory". If type is not
specified, the GPU frequency is implied. The value field can either be "low",
"medium", "high", "highm1" or a numeric value in megahertz (MHz). If the specified
numeric value is not possible, a value as close as possible will be used. See below
for definition of the values. The verbose option causes current GPU frequency
information to be logged. Examples of use include "--gpu-freq=medium,memory=high"
and "--gpu-freq=450".
Supported value definitions:
low the lowest available frequency.
medium attempts to set a frequency in the middle of the available range.
high the highest available frequency.
highm1 (high minus one) will select the next highest available frequency.
--gpus-per-node=[<type>:]<number>
Specify the number of GPUs required for the job on each node included in the job's
resource allocation. An optional GPU type specification can be supplied. For
example "--gpus-per-node=volta:3". Multiple options can be requested in a comma
separated list, for example: "--gpus-per-node=volta:3,kepler:1". See also the
--gpus, --gpus-per-socket and --gpus-per-task options.
--gpus-per-socket=[<type>:]<number>
Specify the number of GPUs required for the job on each socket included in the
job's resource allocation. An optional GPU type specification can be supplied.
For example "--gpus-per-socket=volta:3". Multiple options can be requested in a
comma separated list, for example: "--gpus-per-socket=volta:3,kepler:1". Requires
job to specify a sockets per node count ( --sockets-per-node). See also the
--gpus, --gpus-per-node and --gpus-per-task options.
--gpus-per-task=[<type>:]<number>
Specify the number of GPUs required for the job on each task to be spawned in the
job's resource allocation. An optional GPU type specification can be supplied.
This option requires the specification of a task count. For example
"--gpus-per-task=volta:1". Multiple options can be requested in a comma separated
list, for example: "--gpus-per-task=volta:3,kepler:1". Requires job to specify a
task count (--nodes). See also the --gpus, --gpus-per-socket and --gpus-per-node
options.
--gres=<list>
Specifies a comma delimited list of generic consumable resources. The format of
each entry on the list is "name[[:type]:count]". The name is that of the
consumable resource. The count is the number of those resources with a default
value of 1. The count can have a suffix of "k" or "K" (multiple of 1024), "m" or
"M" (multiple of 1024 x 1024), "g" or "G" (multiple of 1024 x 1024 x 1024), "t" or
"T" (multiple of 1024 x 1024 x 1024 x 1024), "p" or "P" (multiple of 1024 x 1024 x
1024 x 1024 x 1024). The specified resources will be allocated to the job on each
node. The available generic consumable resources is configurable by the system
administrator. A list of available generic consumable resources will be printed
and the command will exit if the option argument is "help". Examples of use
include "--gres=gpu:2,mic:1", "--gres=gpu:kepler:2", and "--gres=help".
--gres-flags=<type>
Specify generic resource task binding options.
disable-binding
Disable filtering of CPUs with respect to generic resource locality. This
option is currently required to use more CPUs than are bound to a GRES (i.e.
if a GPU is bound to the CPUs on one socket, but resources on more than one
socket are required to run the job). This option may permit a job to be
allocated resources sooner than otherwise possible, but may result in lower
job performance.
enforce-binding
The only CPUs available to the job will be those bound to the selected GRES
(i.e. the CPUs identified in the gres.conf file will be strictly enforced).
This option may result in delayed initiation of a job. For example a job
requiring two GPUs and one CPU will be delayed until both GPUs on a single
socket are available rather than using GPUs bound to separate sockets,
however the application performance may be improved due to improved
communication speed. Requires the node to be configured with more than one
socket and resource filtering will be performed on a per-socket basis.
-H, --hold
Specify the job is to be submitted in a held state (priority of zero). A held job
can now be released using scontrol to reset its priority (e.g. "scontrol release
<job_id>").
-h, --help
Display help information and exit.
--hint=<type>
Bind tasks according to application hints.
compute_bound
Select settings for compute bound applications: use all cores in each
socket, one thread per core.
memory_bound
Select settings for memory bound applications: use only one core in each
socket, one thread per core.
[no]multithread
[don't] use extra threads with in-core multi-threading which can benefit
communication intensive applications. Only supported with the task/affinity
plugin.
help show this help message
--ignore-pbs
Ignore any "#PBS" options specified in the batch script.
-i, --input=<filename pattern>
Instruct Slurm to connect the batch script's standard input directly to the file
name specified in the "filename pattern".
By default, "/dev/null" is open on the batch script's standard input and both
standard output and standard error are directed to a file of the name
"slurm-%j.out", where the "%j" is replaced with the job allocation number, as
described below in the filename pattern section.
-J, --job-name=<jobname>
Specify a name for the job allocation. The specified name will appear along with
the job id number when querying running jobs on the system. The default is the name
of the batch script, or just "sbatch" if the script is read on sbatch's standard
input.
-k, --no-kill [=off]
Do not automatically terminate a job if one of the nodes it has been allocated
fails. The user will assume the responsibilities for fault-tolerance should a node
fail. When there is a node failure, any active job steps (usually MPI jobs) on
that node will almost certainly suffer a fatal error, but with --no-kill, the job
allocation will not be revoked so the user may launch new job steps on the
remaining nodes in their allocation.
Specify an optional argument of "off" disable the effect of the SBATCH_NO_KILL
environment variable.
By default Slurm terminates the entire job allocation if any node fails in its
range of allocated nodes.
--kill-on-invalid-dep=<yes|no>
If a job has an invalid dependency and it can never run this parameter tells Slurm
to terminate it or not. A terminated job state will be JOB_CANCELLED. If this
option is not specified the system wide behavior applies. By default the job stays
pending with reason DependencyNeverSatisfied or if the kill_invalid_depend is
specified in slurm.conf the job is terminated.
-L, --licenses=<license>
Specification of licenses (or other resources available on all nodes of the
cluster) which must be allocated to this job. License names can be followed by a
colon and count (the default count is one). Multiple license names should be comma
separated (e.g. "--licenses=foo:4,bar"). To submit jobs using remote licenses,
those served by the slurmdbd, specify the name of the server providing the
licenses. For example "--license=nastran@slurmdb:12".
-M, --clusters=<string>
Clusters to issue commands to. Multiple cluster names may be comma separated. The
job will be submitted to the one cluster providing the earliest expected job
initiation time. The default value is the current cluster. A value of 'all' will
query to run on all clusters. Note the --export option to control environment
variables exported between clusters. Note that the SlurmDBD must be up for this
option to work properly.
-m, --distribution=
arbitrary|<block|cyclic|plane=<options>[:block|cyclic|fcyclic]>
Specify alternate distribution methods for remote processes. In sbatch, this only
sets environment variables that will be used by subsequent srun requests. This
option controls the assignment of tasks to the nodes on which resources have been
allocated, and the distribution of those resources to tasks for binding (task
affinity). The first distribution method (before the ":") controls the distribution
of resources across nodes. The optional second distribution method (after the ":")
controls the distribution of resources across sockets within a node. Note that
with select/cons_res, the number of cpus allocated on each socket and node may be
different. Refer to https://slurm.schedmd.com/mc_support.html for more information
on resource allocation, assignment of tasks to nodes, and binding of tasks to CPUs.
First distribution method:
block The block distribution method will distribute tasks to a node such that
consecutive tasks share a node. For example, consider an allocation of three
nodes each with two cpus. A four-task block distribution request will
distribute those tasks to the nodes with tasks one and two on the first
node, task three on the second node, and task four on the third node. Block
distribution is the default behavior if the number of tasks exceeds the
number of allocated nodes.
cyclic The cyclic distribution method will distribute tasks to a node such that
consecutive tasks are distributed over consecutive nodes (in a round-robin
fashion). For example, consider an allocation of three nodes each with two
cpus. A four-task cyclic distribution request will distribute those tasks to
the nodes with tasks one and four on the first node, task two on the second
node, and task three on the third node. Note that when SelectType is
select/cons_res, the same number of CPUs may not be allocated on each node.
Task distribution will be round-robin among all the nodes with CPUs yet to
be assigned to tasks. Cyclic distribution is the default behavior if the
number of tasks is no larger than the number of allocated nodes.
plane The tasks are distributed in blocks of a specified size. The options
include a number representing the size of the task block. This is followed
by an optional specification of the task distribution scheme within a block
of tasks and between the blocks of tasks. The number of tasks distributed
to each node is the same as for cyclic distribution, but the taskids
assigned to each node depend on the plane size. For more details (including
examples and diagrams), please see
https://slurm.schedmd.com/mc_support.html
and
https://slurm.schedmd.com/dist_plane.html
arbitrary
The arbitrary method of distribution will allocate processes in-order as
listed in file designated by the environment variable SLURM_HOSTFILE. If
this variable is listed it will override any other method specified. If not
set the method will default to block. Inside the hostfile must contain at
minimum the number of hosts requested and be one per line or comma
separated. If specifying a task count (-n, --ntasks=<number>), your tasks
will be laid out on the nodes in the order of the file.
NOTE: The arbitrary distribution option on a job allocation only controls
the nodes to be allocated to the job and not the allocation of CPUs on those
nodes. This option is meant primarily to control a job step's task layout in
an existing job allocation for the srun command.
Second distribution method:
block The block distribution method will distribute tasks to sockets such that
consecutive tasks share a socket.
cyclic The cyclic distribution method will distribute tasks to sockets such that
consecutive tasks are distributed over consecutive sockets (in a round-robin
fashion). Tasks requiring more than one CPU will have all of those CPUs
allocated on a single socket if possible.
fcyclic
The fcyclic distribution method will distribute tasks to sockets such that
consecutive tasks are distributed over consecutive sockets (in a round-robin
fashion). Tasks requiring more than one CPU will have each CPUs allocated
in a cyclic fashion across sockets.
--mail-type=<type>
Notify user by email when certain event types occur. Valid type values are NONE,
BEGIN, END, FAIL, REQUEUE, ALL (equivalent to BEGIN, END, FAIL, REQUEUE, and
STAGE_OUT), STAGE_OUT (burst buffer stage out and teardown completed), TIME_LIMIT,
TIME_LIMIT_90 (reached 90 percent of time limit), TIME_LIMIT_80 (reached 80 percent
of time limit), TIME_LIMIT_50 (reached 50 percent of time limit) and ARRAY_TASKS
(send emails for each array task). Multiple type values may be specified in a comma
separated list. The user to be notified is indicated with --mail-user. Unless the
ARRAY_TASKS option is specified, mail notifications on job BEGIN, END and FAIL
apply to a job array as a whole rather than generating individual email messages
for each task in the job array.
--mail-user=<user>
User to receive email notification of state changes as defined by --mail-type. The
default value is the submitting user.
--mcs-label=<mcs>
Used only when the mcs/group plugin is enabled. This parameter is a group among
the groups of the user. Default value is calculated by the Plugin mcs if it's
enabled.
--mem=<size[units]>
Specify the real memory required per node. Default units are megabytes unless the
SchedulerParameters configuration parameter includes the "default_gbytes" option
for gigabytes. Different units can be specified using the suffix [K|M|G|T].
Default value is DefMemPerNode and the maximum value is MaxMemPerNode. If
configured, both parameters can be seen using the scontrol show config command.
This parameter would generally be used if whole nodes are allocated to jobs
(SelectType=select/linear). Also see --mem-per-cpu and --mem-per-gpu. The --mem,
--mem-per-cpu and --mem-per-gpu options are mutually exclusive. If --mem,
--mem-per-cpu or --mem-per-gpu are specified as command line arguments, then they
will take precedence over the environment.
NOTE: A memory size specification of zero is treated as a special case and grants
the job access to all of the memory on each node. If the job is allocated multiple
nodes in a heterogeneous cluster, the memory limit on each node will be that of the
node in the allocation with the smallest memory size (same limit will apply to
every node in the job's allocation).
NOTE: Enforcement of memory limits currently relies upon the task/cgroup plugin or
enabling of accounting, which samples memory use on a periodic basis (data need not
be stored, just collected). In both cases memory use is based upon the job's
Resident Set Size (RSS). A task may exceed the memory limit until the next periodic
accounting sample.
--mem-per-cpu=<size[units]>
Minimum memory required per allocated CPU. Default units are megabytes unless the
SchedulerParameters configuration parameter includes the "default_gbytes" option
for gigabytes. Default value is DefMemPerCPU and the maximum value is MaxMemPerCPU
(see exception below). If configured, both parameters can be seen using the
scontrol show config command. Note that if the job's --mem-per-cpu value exceeds
the configured MaxMemPerCPU, then the user's limit will be treated as a memory
limit per task; --mem-per-cpu will be reduced to a value no larger than
MaxMemPerCPU; --cpus-per-task will be set and the value of --cpus-per-task
multiplied by the new --mem-per-cpu value will equal the original --mem-per-cpu
value specified by the user. This parameter would generally be used if individual
processors are allocated to jobs (SelectType=select/cons_res). If resources are
allocated by the core, socket or whole nodes; the number of CPUs allocated to a job
may be higher than the task count and the value of --mem-per-cpu should be adjusted
accordingly. Also see --mem and --mem-per-gpu. The --mem, --mem-per-cpu and
--mem-per-gpu options are mutually exclusive.
NOTE:If the final amount of memory requested by job (eg.: when --mem-per-cpu use
with --exclusive option) can't be satisfied by any of nodes configured in the
partition, the job will be rejected.
--mem-per-gpu=<size[units]>
Minimum memory required per allocated GPU. Default units are megabytes unless the
SchedulerParameters configuration parameter includes the "default_gbytes" option
for gigabytes. Different units can be specified using the suffix [K|M|G|T].
Default value is DefMemPerGPU and is available on both a global and per partition
basis. If configured, the parameters can be seen using the scontrol show config
and scontrol show partition commands. Also see --mem. The --mem, --mem-per-cpu
and --mem-per-gpu options are mutually exclusive.
--mem-bind=[{quiet,verbose},]type
Bind tasks to memory. Used only when the task/affinity plugin is enabled and the
NUMA memory functions are available. Note that the resolution of CPU and memory
binding may differ on some architectures. For example, CPU binding may be performed
at the level of the cores within a processor while memory binding will be performed
at the level of nodes, where the definition of "nodes" may differ from system to
system. By default no memory binding is performed; any task using any CPU can use
any memory. This option is typically used to ensure that each task is bound to the
memory closest to it's assigned CPU. The use of any type other than "none" or
"local" is not recommended. If you want greater control, try running a simple test
code with the options "--cpu-bind=verbose,none --mem-bind=verbose,none" to
determine the specific configuration.
NOTE: To have Slurm always report on the selected memory binding for all commands
executed in a shell, you can enable verbose mode by setting the SLURM_MEM_BIND
environment variable value to "verbose".
The following informational environment variables are set when --mem-bind is in
use:
SLURM_MEM_BIND_LIST
SLURM_MEM_BIND_PREFER
SLURM_MEM_BIND_SORT
SLURM_MEM_BIND_TYPE
SLURM_MEM_BIND_VERBOSE
See the ENVIRONMENT VARIABLES section for a more detailed description of the
individual SLURM_MEM_BIND* variables.
Supported options include:
help show this help message
local Use memory local to the processor in use
map_mem:<list>
Bind by setting memory masks on tasks (or ranks) as specified where <list>
is <numa_id_for_task_0>,<numa_id_for_task_1>,... The mapping is specified
for a node and identical mapping is applied to the tasks on every node (i.e.
the lowest task ID on each node is mapped to the first ID specified in the
list, etc.). NUMA IDs are interpreted as decimal values unless they are
preceded with '0x' in which case they interpreted as hexadecimal values. If
the number of tasks (or ranks) exceeds the number of elements in this list,
elements in the list will be reused as needed starting from the beginning of
the list. To simplify support for large task counts, the lists may follow a
map with an asterisk and repetition count For example
"map_mem:0x0f*4,0xf0*4". Not supported unless the entire node is allocated
to the job.
mask_mem:<list>
Bind by setting memory masks on tasks (or ranks) as specified where <list>
is <numa_mask_for_task_0>,<numa_mask_for_task_1>,... The mapping is
specified for a node and identical mapping is applied to the tasks on every
node (i.e. the lowest task ID on each node is mapped to the first mask
specified in the list, etc.). NUMA masks are always interpreted as
hexadecimal values. Note that masks must be preceded with a '0x' if they
don't begin with [0-9] so they are seen as numerical values. If the number
of tasks (or ranks) exceeds the number of elements in this list, elements in
the list will be reused as needed starting from the beginning of the list.
To simplify support for large task counts, the lists may follow a mask with
an asterisk and repetition count For example "mask_mem:0*4,1*4". Not
supported unless the entire node is allocated to the job.
no[ne] don't bind tasks to memory (default)
p[refer]
Prefer use of first specified NUMA node, but permit
use of other available NUMA nodes.
q[uiet]
quietly bind before task runs (default)
rank bind by task rank (not recommended)
sort sort free cache pages (run zonesort on Intel KNL nodes)
v[erbose]
verbosely report binding before task runs
--mincpus=<n>
Specify a minimum number of logical cpus/processors per node.
-N, --nodes=<minnodes[-maxnodes]>
Request that a minimum of minnodes nodes be allocated to this job. A maximum node
count may also be specified with maxnodes. If only one number is specified, this
is used as both the minimum and maximum node count. The partition's node limits
supersede those of the job. If a job's node limits are outside of the range
permitted for its associated partition, the job will be left in a PENDING state.
This permits possible execution at a later time, when the partition limit is
changed. If a job node limit exceeds the number of nodes configured in the
partition, the job will be rejected. Note that the environment variable
SLURM_JOB_NODES will be set to the count of nodes actually allocated to the job.
See the ENVIRONMENT VARIABLES section for more information. If -N is not
specified, the default behavior is to allocate enough nodes to satisfy the
requirements of the -n and -c options. The job will be allocated as many nodes as
possible within the range specified and without delaying the initiation of the job.
The node count specification may include a numeric value followed by a suffix of
"k" (multiplies numeric value by 1,024) or "m" (multiplies numeric value by
1,048,576).
-n, --ntasks=<number>
sbatch does not launch tasks, it requests an allocation of resources and submits a
batch script. This option advises the Slurm controller that job steps run within
the allocation will launch a maximum of number tasks and to provide for sufficient
resources. The default is one task per node, but note that the --cpus-per-task
option will change this default.
--network=<type>
Specify information pertaining to the switch or network. The interpretation of
type is system dependent. This option is supported when running Slurm on a Cray
natively. It is used to request using Network Performance Counters. Only one
value per request is valid. All options are case in-sensitive. In this
configuration supported values include:
system
Use the system-wide network performance counters. Only nodes requested will
be marked in use for the job allocation. If the job does not fill up the
entire system the rest of the nodes are not able to be used by other jobs
using NPC, if idle their state will appear as PerfCnts. These nodes are
still available for other jobs not using NPC.
blade Use the blade network performance counters. Only nodes requested will be
marked in use for the job allocation. If the job does not fill up the entire
blade(s) allocated to the job those blade(s) are not able to be used by other
jobs using NPC, if idle their state will appear as PerfCnts. These nodes are
still available for other jobs not using NPC.
In all cases the job allocation request must specify the
--exclusive option. Otherwise the request will be denied.
Also with any of these options steps are not allowed to share blades, so resources
would remain idle inside an allocation if the step running on a blade does not take
up all the nodes on the blade.
The network option is also supported on systems with IBM's Parallel Environment
(PE). See IBM's LoadLeveler job command keyword documentation about the keyword
"network" for more information. Multiple values may be specified in a comma
separated list. All options are case in-sensitive. Supported values include:
BULK_XFER[=<resources>]
Enable bulk transfer of data using Remote Direct-Memory Access (RDMA).
The optional resources specification is a numeric value which can have
a suffix of "k", "K", "m", "M", "g" or "G" for kilobytes, megabytes or
gigabytes. NOTE: The resources specification is not supported by the
underlying IBM infrastructure as of Parallel Environment version 2.2
and no value should be specified at this time.
CAU=<count> Number of Collective Acceleration Units (CAU) required. Applies only
to IBM Power7-IH processors. Default value is zero. Independent CAU
will be allocated for each programming interface (MPI, LAPI, etc.)
DEVNAME=<name>
Specify the device name to use for communications (e.g. "eth0" or
"mlx4_0").
DEVTYPE=<type>
Specify the device type to use for communications. The supported
values of type are: "IB" (InfiniBand), "HFI" (P7 Host Fabric
Interface), "IPONLY" (IP-Only interfaces), "HPCE" (HPC Ethernet), and
"KMUX" (Kernel Emulation of HPCE). The devices allocated to a job must
all be of the same type. The default value depends upon depends upon
what hardware is available and in order of preferences is IPONLY (which
is not considered in User Space mode), HFI, IB, HPCE, and KMUX.
IMMED =<count>
Number of immediate send slots per window required. Applies only to
IBM Power7-IH processors. Default value is zero.
INSTANCES =<count>
Specify number of network connections for each task on each network
connection. The default instance count is 1.
IPV4 Use Internet Protocol (IP) version 4 communications (default).
IPV6 Use Internet Protocol (IP) version 6 communications.
LAPI Use the LAPI programming interface.
MPI Use the MPI programming interface. MPI is the default interface.
PAMI Use the PAMI programming interface.
SHMEM Use the OpenSHMEM programming interface.
SN_ALL Use all available switch networks (default).
SN_SINGLE Use one available switch network.
UPC Use the UPC programming interface.
US Use User Space communications.
Some examples of network specifications:
Instances=2,US,MPI,SN_ALL
Create two user space connections for MPI communications on every
switch network for each task.
US,MPI,Instances=3,Devtype=IB
Create three user space connections for MPI communications on every
InfiniBand network for each task.
IPV4,LAPI,SN_Single
Create a IP version 4 connection for LAPI communications on one switch
network for each task.
Instances=2,US,LAPI,MPI
Create two user space connections each for LAPI and MPI communications
on every switch network for each task. Note that SN_ALL is the default
option so every switch network is used. Also note that Instances=2
specifies that two connections are established for each protocol (LAPI
and MPI) and each task. If there are two networks and four tasks on
the node then a total of 32 connections are established (2 instances x
2 protocols x 2 networks x 4 tasks).
--nice[=adjustment]
Run the job with an adjusted scheduling priority within Slurm. With no adjustment
value the scheduling priority is decreased by 100. A negative nice value increases
the priority, otherwise decreases it. The adjustment range is +/- 2147483645. Only
privileged users can specify a negative adjustment.
--no-requeue
Specifies that the batch job should never be requeued under any circumstances.
Setting this option will prevent system administrators from being able to restart
the job (for example, after a scheduled downtime), recover from a node failure, or
be requeued upon preemption by a higher priority job. When a job is requeued, the
batch script is initiated from its beginning. Also see the --requeue option. The
JobRequeue configuration parameter controls the default behavior on the cluster.
--ntasks-per-core=<ntasks>
Request the maximum ntasks be invoked on each core. Meant to be used with the
--ntasks option. Related to --ntasks-per-node except at the core level instead of
the node level. NOTE: This option is not supported unless SelectType=cons_res is
configured (either directly or indirectly on Cray systems) along with the node's
core count.
--ntasks-per-node=<ntasks>
Request that ntasks be invoked on each node. If used with the --ntasks option, the
--ntasks option will take precedence and the --ntasks-per-node will be treated as a
maximum count of tasks per node. Meant to be used with the --nodes option. This
is related to --cpus-per-task=ncpus, but does not require knowledge of the actual
number of cpus on each node. In some cases, it is more convenient to be able to
request that no more than a specific number of tasks be invoked on each node.
Examples of this include submitting a hybrid MPI/OpenMP app where only one MPI
"task/rank" should be assigned to each node while allowing the OpenMP portion to
utilize all of the parallelism present in the node, or submitting a single
setup/cleanup/monitoring job to each node of a pre-existing allocation as one step
in a larger job script.
--ntasks-per-socket=<ntasks>
Request the maximum ntasks be invoked on each socket. Meant to be used with the
--ntasks option. Related to --ntasks-per-node except at the socket level instead
of the node level. NOTE: This option is not supported unless SelectType=cons_res
is configured (either directly or indirectly on Cray systems) along with the node's
socket count.
-O, --overcommit
Overcommit resources. When applied to job allocation, only one CPU is allocated to
the job per node and options used to specify the number of tasks per node, socket,
core, etc. are ignored. When applied to job step allocations (the srun command
when executed within an existing job allocation), this option can be used to launch
more than one task per CPU. Normally, srun will not allocate more than one process
per CPU. By specifying --overcommit you are explicitly allowing more than one
process per CPU. However no more than MAX_TASKS_PER_NODE tasks are permitted to
execute per node. NOTE: MAX_TASKS_PER_NODE is defined in the file slurm.h and is
not a variable, it is set at Slurm build time.
-o, --output=<filename pattern>
Instruct Slurm to connect the batch script's standard output directly to the file
name specified in the "filename pattern". By default both standard output and
standard error are directed to the same file. For job arrays, the default file
name is "slurm-%A_%a.out", "%A" is replaced by the job ID and "%a" with the array
index. For other jobs, the default file name is "slurm-%j.out", where the "%j" is
replaced by the job ID. See the filename pattern section below for filename
specification options.
--open-mode=append|truncate
Open the output and error files using append or truncate mode as specified. The
default value is specified by the system configuration parameter JobFileAppend.
--parsable
Outputs only the job id number and the cluster name if present. The values are
separated by a semicolon. Errors will still be displayed.
-p, --partition=<partition_names>
Request a specific partition for the resource allocation. If not specified, the
default behavior is to allow the slurm controller to select the default partition
as designated by the system administrator. If the job can use more than one
partition, specify their names in a comma separate list and the one offering
earliest initiation will be used with no regard given to the partition name
ordering (although higher priority partitions will be considered first). When the
job is initiated, the name of the partition used will be placed first in the job
record partition string.
--power=<flags>
Comma separated list of power management plugin options. Currently available flags
include: level (all nodes allocated to the job should have identical power caps,
may be disabled by the Slurm configuration option PowerParameters=job_no_level).
--priority=<value>
Request a specific job priority. May be subject to configuration specific
constraints. value should either be a numeric value or "TOP" (for highest possible
value). Only Slurm operators and administrators can set the priority of a job.
--profile=<all|none|[energy[,|task[,|lustre[,|network]]]]>
enables detailed data collection by the acct_gather_profile plugin. Detailed data
are typically time-series that are stored in an HDF5 file for the job or an
InfluxDB database depending on the configured plugin.
All All data types are collected. (Cannot be combined with other values.)
None No data types are collected. This is the default.
(Cannot be combined with other values.)
Energy Energy data is collected.
Task Task (I/O, Memory, ...) data is collected.
Lustre Lustre data is collected.
Network Network (InfiniBand) data is collected.
--propagate[=rlimit[,rlimit...]]
Allows users to specify which of the modifiable (soft) resource limits to propagate
to the compute nodes and apply to their jobs. If no rlimit is specified, then all
resource limits will be propagated. The following rlimit names are supported by
Slurm (although some options may not be supported on some systems):
ALL All limits listed below (default)
NONE No limits listed below
AS The maximum address space for a process
CORE The maximum size of core file
CPU The maximum amount of CPU time
DATA The maximum size of a process's data segment
FSIZE The maximum size of files created. Note that if the user sets FSIZE to
less than the current size of the slurmd.log, job launches will fail with
a 'File size limit exceeded' error.
MEMLOCK The maximum size that may be locked into memory
NOFILE The maximum number of open files
NPROC The maximum number of processes available
RSS The maximum resident set size
STACK The maximum stack size
-q, --qos=<qos>
Request a quality of service for the job. QOS values can be defined for each
user/cluster/account association in the Slurm database. Users will be limited to
their association's defined set of qos's when the Slurm configuration parameter,
AccountingStorageEnforce, includes "qos" in it's definition.
-Q, --quiet
Suppress informational messages from sbatch such as Job ID. Only errors will still
be displayed.
--reboot
Force the allocated nodes to reboot before starting the job. This is only
supported with some system configurations and will otherwise be silently ignored.
--requeue
Specifies that the batch job should eligible to being requeue. The job may be
requeued explicitly by a system administrator, after node failure, or upon
preemption by a higher priority job. When a job is requeued, the batch script is
initiated from its beginning. Also see the --no-requeue option. The JobRequeue
configuration parameter controls the default behavior on the cluster.
--reservation=<name>
Allocate resources for the job from the named reservation.
-s, --oversubscribe
The job allocation can over-subscribe resources with other running jobs. The
resources to be over-subscribed can be nodes, sockets, cores, and/or hyperthreads
depending upon configuration. The default over-subscribe behavior depends on
system configuration and the partition's OverSubscribe option takes precedence over
the job's option. This option may result in the allocation being granted sooner
than if the --oversubscribe option was not set and allow higher system utilization,
but application performance will likely suffer due to competition for resources.
Also see the --exclusive option.
-S, --core-spec=<num>
Count of specialized cores per node reserved by the job for system operations and
not used by the application. The application will not use these cores, but will be
charged for their allocation. Default value is dependent upon the node's
configured CoreSpecCount value. If a value of zero is designated and the Slurm
configuration option AllowSpecResourcesUsage is enabled, the job will be allowed to
override CoreSpecCount and use the specialized resources on nodes it is allocated.
This option can not be used with the --thread-spec option.
--signal=[B:]<sig_num>[@<sig_time>]
When a job is within sig_time seconds of its end time, send it the signal sig_num.
Due to the resolution of event handling by Slurm, the signal may be sent up to 60
seconds earlier than specified. sig_num may either be a signal number or name
(e.g. "10" or "USR1"). sig_time must have an integer value between 0 and 65535.
By default, no signal is sent before the job's end time. If a sig_num is specified
without any sig_time, the default time will be 60 seconds. Use the "B:" option to
signal only the batch shell, none of the other processes will be signaled. By
default all job steps will be signaled, but not the batch shell itself. To have
the signal sent at preemption time see the preempt_send_user_signal
SlurmctldParameter.
--sockets-per-node=<sockets>
Restrict node selection to nodes with at least the specified number of sockets.
See additional information under -B option above when task/affinity plugin is
enabled.
--spread-job
Spread the job allocation over as many nodes as possible and attempt to evenly
distribute tasks across the allocated nodes. This option disables the
topology/tree plugin.
--switches=<count>[@<max-time>]
When a tree topology is used, this defines the maximum count of switches desired
for the job allocation and optionally the maximum time to wait for that number of
switches. If Slurm finds an allocation containing more switches than the count
specified, the job remains pending until it either finds an allocation with desired
switch count or the time limit expires. It there is no switch count limit, there
is no delay in starting the job. Acceptable time formats include "minutes",
"minutes:seconds", "hours:minutes:seconds", "days-hours", "days-hours:minutes" and
"days-hours:minutes:seconds". The job's maximum time delay may be limited by the
system administrator using the SchedulerParameters configuration parameter with the
max_switch_wait parameter option. On a dragonfly network the only switch count
supported is 1 since communication performance will be highest when a job is
allocate resources on one leaf switch or more than 2 leaf switches. The default
max-time is the max_switch_wait SchedulerParameters.
-t, --time=<time>
Set a limit on the total run time of the job allocation. If the requested time
limit exceeds the partition's time limit, the job will be left in a PENDING state
(possibly indefinitely). The default time limit is the partition's default time
limit. When the time limit is reached, each task in each job step is sent SIGTERM
followed by SIGKILL. The interval between signals is specified by the Slurm
configuration parameter KillWait. The OverTimeLimit configuration parameter may
permit the job to run longer than scheduled. Time resolution is one minute and
second values are rounded up to the next minute.
A time limit of zero requests that no time limit be imposed. Acceptable time
formats include "minutes", "minutes:seconds", "hours:minutes:seconds",
"days-hours", "days-hours:minutes" and "days-hours:minutes:seconds".
--test-only
Validate the batch script and return an estimate of when a job would be scheduled
to run given the current job queue and all the other arguments specifying the job
requirements. No job is actually submitted.
--thread-spec=<num>
Count of specialized threads per node reserved by the job for system operations and
not used by the application. The application will not use these threads, but will
be charged for their allocation. This option can not be used with the --core-spec
option.
--threads-per-core=<threads>
Restrict node selection to nodes with at least the specified number of threads per
core. NOTE: "Threads" refers to the number of processing units on each core rather
than the number of application tasks to be launched per core. See additional
information under -B option above when task/affinity plugin is enabled.
--time-min=<time>
Set a minimum time limit on the job allocation. If specified, the job may have
it's --time limit lowered to a value no lower than --time-min if doing so permits
the job to begin execution earlier than otherwise possible. The job's time limit
will not be changed after the job is allocated resources. This is performed by a
backfill scheduling algorithm to allocate resources otherwise reserved for higher
priority jobs. Acceptable time formats include "minutes", "minutes:seconds",
"hours:minutes:seconds", "days-hours", "days-hours:minutes" and
"days-hours:minutes:seconds".
--tmp=<size[units]>
Specify a minimum amount of temporary disk space per node. Default units are
megabytes unless the SchedulerParameters configuration parameter includes the
"default_gbytes" option for gigabytes. Different units can be specified using the
suffix [K|M|G|T].
--usage
Display brief help message and exit.
--uid=<user>
Attempt to submit and/or run a job as user instead of the invoking user id. The
invoking user's credentials will be used to check access permissions for the target
partition. User root may use this option to run jobs as a normal user in a RootOnly
partition for example. If run as root, sbatch will drop its permissions to the uid
specified after node allocation is successful. user may be the user name or
numerical user ID.
--use-min-nodes
If a range of node counts is given, prefer the smaller count.
-V, --version
Display version information and exit.
-v, --verbose
Increase the verbosity of sbatch's informational messages. Multiple -v's will
further increase sbatch's verbosity. By default only errors will be displayed.
-w, --nodelist=<node name list>
Request a specific list of hosts. The job will contain all of these hosts and
possibly additional hosts as needed to satisfy resource requirements. The list may
be specified as a comma-separated list of hosts, a range of hosts (host[1-5,7,...]
for example), or a filename. The host list will be assumed to be a filename if it
contains a "/" character. If you specify a minimum node or processor count larger
than can be satisfied by the supplied host list, additional resources will be
allocated on other nodes as needed. Duplicate node names in the list will be
ignored. The order of the node names in the list is not important; the node names
will be sorted by Slurm.
-W, --wait
Do not exit until the submitted job terminates. The exit code of the sbatch
command will be the same as the exit code of the submitted job. If the job
terminated due to a signal rather than a normal exit, the exit code will be set to
1. In the case of a job array, the exit code recorded will be the highest value
for any task in the job array.
--wait-all-nodes=<value>
Controls when the execution of the command begins. By default the job will begin
execution as soon as the allocation is made.
0 Begin execution as soon as allocation can be made. Do not wait for all nodes
to be ready for use (i.e. booted).
1 Do not begin execution until all nodes are ready for use.
--wckey=<wckey>
Specify wckey to be used with job. If TrackWCKey=no (default) in the slurm.conf
this value is ignored.
--wrap=<command string>
Sbatch will wrap the specified command string in a simple "sh" shell script, and
submit that script to the slurm controller. When --wrap is used, a script name and
arguments may not be specified on the command line; instead the sbatch-generated
wrapper script is used.
-x, --exclude=<node name list>
Explicitly exclude certain nodes from the resources granted to the job.
filename pattern
sbatch allows for a filename pattern to contain one or more replacement symbols, which are
a percent sign "%" followed by a letter (e.g. %j).
\\ Do not process any of the replacement symbols.
%% The character "%".
%A Job array's master job allocation number.
%a Job array ID (index) number.
%J jobid.stepid of the running job. (e.g. "128.0")
%j jobid of the running job.
%N short hostname. This will create a separate IO file per node.
%n Node identifier relative to current job (e.g. "0" is the first node of the running
job) This will create a separate IO file per node.
%s stepid of the running job.
%t task identifier (rank) relative to current job. This will create a separate IO file
per task.
%u User name.
%x Job name.
A number placed between the percent character and format specifier may be used to zero-pad
the result in the IO filename. This number is ignored if the format specifier corresponds
to non-numeric data (%N for example).
Some examples of how the format string may be used for a 4 task job step with a Job ID of
128 and step id of 0 are included below:
job%J.out job128.0.out
job%4j.out job0128.out
job%j-%2t.out job128-00.out, job128-01.out, ...

nodes will each execute three tasks and the fourth node will execute one task.
SLURM_TASK_PID
The process ID of the task being started.
SLURM_TOPOLOGY_ADDR
This is set only if the system has the topology/tree plugin configured. The
