NAME
sbatch - Submit a batch script to SLURM.
SYNOPSIS
sbatch [options] script [args...]
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 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.
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.
OPTIONS
-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=<seconds>
Define the job accounting sampling interval. This can be used
to override the JobAcctGatherFrequency parameter in SLURM’s
configuration file, slurm.conf. A value of zero disables real
the periodic job sampling and provides accounting information
only on job termination (reducing SLURM interference with the
job).
-B --extra-node-info=<sockets[:cores[:threads]]>
Request a specific allocation of resources with details as to
the number and type of computational resources within a cluster:
number of sockets (or physical processors) per node, cores per
socket, and threads per core. The total amount of resources
being requested is the product of all of the terms. 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. As with nodes, 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 sets a default --cpu_bind option
of 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. This option is not supported on BlueGene systems
(select/bluegene plugin is configured).
--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,
or teatime (4pm) 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 no checkpoints created.
Acceptable time formats include "minutes", "minutes:seconds",
"hours:minutes:seconds", "days-hours", "days-hours:minutes" and
"days-hours:minutes:seconds".
--checkpoint-dir=<directory>
Specifies the directory into which the job or job step’s
checkpoint should be written (used by the checkpoint/blcrm and
checkpoint/xlch plugins only). The default value is the current
working directory. Checkpoint files will be of the form
"<job_id>.ckpt" for jobs and "<job_id>.<step_id>.ckpt" for job
steps.
--comment=<string>
An arbitrary comment.
-C, --constraint=<list>
Specify a list of constraints. The constraints are features
that have been assigned to the nodes by the slurm administrator.
The list of constraints may include multiple features separated
by ampersand (AND) and/or vertical bar (OR) operators. For
example: --constraint="opteron&video" or
--constraint="fast|faster". In the first example, only nodes
having both the feature "opteron" AND the feature "video" will
be used. There is no mechanism to specify that you want one
node with feature "opteron" and another node with feature
"video" in case no node has both features. 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. A request can also specify the number of nodes needed
with some feature by appending an asterisk and count after the
feature name. For example "sbatch --nodes=16
--constraint=graphics*4 ..." indicates that the job requires 16
nodes at that at least four of those nodes must have the feature
"graphics." Constraints with node counts may only be combined
with AND operators. If no nodes have the requested features,
then the job will be rejected by the slurm job manager.
--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.
--cpu_bind=[{quiet,verbose},]type
Bind tasks to CPUs. Used only when the task/affinity plugin is
enabled. The configuration parameter TaskPluginParam may
override these options. For example, if TaskPluginParam is
configured to bind to cores, your job will not be able to bind
tasks to sockets. NOTE: To have SLURM always report on the
selected CPU binding for all commands executed in a shell, you
can enable verbose mode by setting the SLURM_CPU_BIND
environment variable value to "verbose".
The following informational environment variables are set when
--cpu_bind is in use:
SLURM_CPU_BIND_VERBOSE
SLURM_CPU_BIND_TYPE
SLURM_CPU_BIND_LIST
See the ENVIRONMENT VARIABLE section for a more detailed
description of the individual SLURM_CPU_BIND* variables.
When using --cpus-per-task to run multithreaded tasks, be aware
that CPU binding is inherited from the parent of the process.
This means that the multithreaded task should either specify or
clear the CPU binding itself to avoid having all threads of the
multithreaded task use the same mask/CPU as the parent.
Alternatively, fat masks (masks which specify more than one
allowed CPU) could be used for the tasks in order to provide
multiple CPUs for the multithreaded tasks.
By default, a job step has access to every CPU allocated to the
job. To ensure that distinct CPUs are allocated to each job
step, use the --exclusive option.
If the job step allocation includes an allocation with a number
of sockets, cores, or threads equal to the number of tasks to be
started then the tasks will by default be bound to the
appropriate resources. Disable this mode of operation by
explicitly setting "--cpu-bind=none".
Note that a job step can be allocated different numbers of CPUs
on each node or be allocated CPUs not starting at location zero.
Therefore one of the options which automatically generate the
task binding is recommended. Explicitly specified masks or
bindings are only honored when the job step has been allocated
every available CPU on the node.
Binding a task to a NUMA locality domain means to bind the task
to the set of CPUs that belong to the NUMA locality domain or
"NUMA node". If NUMA locality domain options are used on
systems with no NUMA support, then each socket is considered a
locality domain.
Supported options include:
q[uiet]
Quietly bind before task runs (default)
v[erbose]
Verbosely report binding before task runs
no[ne] Do not bind tasks to CPUs (default)
rank Automatically bind by task rank. Task zero is bound to
socket (or core or thread) zero, etc. Not supported
unless the entire node is allocated to the job.
map_cpu:<list>
Bind by mapping CPU IDs to tasks as specified where
<list> is <cpuid1>,<cpuid2>,...<cpuidN>. CPU IDs are
interpreted as decimal values unless they are preceded
with ’0x’ in which case they are interpreted as
hexadecimal values. Not supported unless the entire node
is allocated to the job.
mask_cpu:<list>
Bind by setting CPU masks on tasks as specified where
<list> is <mask1>,<mask2>,...<maskN>. CPU masks are
always interpreted as hexadecimal values but can be
preceded with an optional ’0x’.
sockets
Automatically generate masks binding tasks to sockets.
If the number of tasks differs from the number of
allocated sockets this can result in sub-optimal binding.
cores Automatically generate masks binding tasks to cores. If
the number of tasks differs from the number of allocated
cores this can result in sub-optimal binding.
threads
Automatically generate masks binding tasks to threads.
If the number of tasks differs from the number of
allocated threads this can result in sub-optimal binding.
ldoms Automatically generate masks binding tasks to NUMA
locality domains. If the number of tasks differs from
the number of allocated locality domains this can result
in sub-optimal binding.

-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.
-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]]>. 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.
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.
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 non-
zero exit code).
singleton
This job can begin execution after any previously
launched jobs sharing the same job name and user have
terminated.
-D, --workdir=<directory>
Set the working directory of the batch script to directory
before it it 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".
See the --input option for filename specification options.
--exclusive
The job allocation cannot share nodes with other running jobs.
This is the oposite of --share, whichever option is seen last on
the command line will win. (The default shared/exclusive
behaviour depends on system configuration.)
-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". NOTE: This option only works if the caller
has an effective uid of "root". 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.
-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
help show this help message
-I, --immediate
The batch script will only be submitted to the controller if the
resources necessary to grant its job allocation are immediately
available. If the job allocation will have to wait in a queue
of pending jobs, the batch script will not be submitted.
-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.
The filename pattern may contain one or more replacement
symbols, which are a percent sign "%" followed by a letter (e.g.
%j).
Supported replacement symbols are:
%j Job allocation number.
%N Node name. Only one file is created, so %N will be
replaced by the name of the first node in the job,
which is the one that runs the script.
-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.
--jobid=<jobid>
Allocate resources as the specified job id. NOTE: Only valid
for user root.
-k, --no-kill
Do not automatically terminate a job of 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.
By default SLURM terminates the entire job allocation if any
node fails in its range of allocated nodes.
-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 an asterisk and count (the
default count is one). Multiple license names should be comma
separated (e.g. "--licenses=foo*4,bar").
-m, --distribution=
<block|cyclic|arbitrary|plane=<options>> Specify an alternate
distribution method for remote processes. In sbatch, this only
sets environment variables that will be used by subsequent srun
requests.
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. 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. For more
details (including examples and diagrams), please see
https://computing.llnl.gov/linux/slurm/mc_support.html
and
https://computing.llnl.gov/linux/slurm/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 over ride 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. If requesting tasks (-n) your tasks will be
laid out on the nodes in the order of the file.
--mail-type=<type>
Notify user by email when certain event types occur. Valid type
values are BEGIN, END, FAIL, ALL (any state change). The user
to be notified is indicated with --mail-user.
--mail-user=<user>
User to receive email notification of state changes as defined
by --mail-type. The default value is the submitting user.
--mem=<MB>
Specify the real memory required per node in MegaBytes. Default
value is DefMemPerNode and the maximum value is MaxMemPerNode.
If configured, both of 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. --mem and --mem-per-cpu are mutually
exclusive.
--mem-per-cpu=<MB>
Mimimum memory required per allocated CPU in MegaBytes. Default
value is DefMemPerCPU and the maximum value is MaxMemPerCPU. If
configured, both of parameters can be seen using the scontrol
show config command. This parameter would generally be used if
individual processors are allocated to jobs
(SelectType=select/cons_res). Also see --mem. --mem and
--mem-per-cpu 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. 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_bindis in use:
SLURM_MEM_BIND_VERBOSE
SLURM_MEM_BIND_TYPE
SLURM_MEM_BIND_LIST
See the ENVIRONMENT VARIABLES section for a more detailed
description of the individual SLURM_MEM_BIND* variables.
Supported options include:
q[uiet]
quietly bind before task runs (default)
v[erbose]
verbosely report binding before task runs
no[ne] don’t bind tasks to memory (default)
rank bind by task rank (not recommended)
local Use memory local to the processor in use
map_mem:<list>
bind by mapping a node’s memory to tasks as specified
where <list> is <cpuid1>,<cpuid2>,...<cpuidN>. CPU IDs
are interpreted as decimal values unless they are
preceded with ’0x’ in which case they interpreted as
hexadecimal values (not recommended)
mask_mem:<list>
bind by setting memory masks on tasks as specified where
<list> is <mask1>,<mask2>,...<maskN>. memory 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 by srun.
help show this help message
--mincores=<n>
Specify a minimum number of cores per socket.
--mincpus=<n>
Specify a minimum number of logical cpus/processors per node.
--minsockets=<n>
Specify a minimum number of sockets (physical processors) per
node.
--minthreads=<n>
Specify a minimum number of threads per core.
-N, --nodes=<minnodes[-maxnodes]>
Request that a minimum of minnodes nodes be allocated to this
job. The scheduler may decide to launch the job on more than
minnodes nodes. A limit on the maximum node count may be
specified with maxnodes (e.g. "--nodes=2-4"). The minimum and
maximum node count may be the same to specify a specific number
of nodes (e.g. "--nodes=2-2" will ask for two and ONLY two
nodes). 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_NNODES 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.
-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 this allocation will
launch a maximum of number tasks and sufficient resources are
allocated to accomplish this. The default is one task per node,
but note that the --cpus-per-task option will change this
default.
--network=<type>
Specify the communication protocol to be used. This option is
supported on AIX systems. Since POE is used to launch tasks,
this option is not normally used or is specified using the
SLURM_NETWORK environment variable. The interpretation of type
is system dependent. For systems with an IBM Federation switch,
the following comma-separated and case insensitive types are
recognized: IP (the default is user-space), SN_ALL, SN_SINGLE,
BULK_XFER and adapter names (e.g. SNI0 and SNI1). For more
information, on IBM systems see poe documentation on the
environment variables MP_EUIDEVICE and MP_USE_BULK_XFER. Note
that only four jobs steps may be active at once on a node with
the BULK_XFER option due to limitations in the Federation switch
driver.
--nice[=adjustment]
Run the job with an adjusted scheduling priority within SLURM.
With no adjustment value the scheduling priority is decreased by
100. The adjustment range is from -10000 (highest priority) to
10000 (lowest priority). Only privileged users can specify a
negative adjustment. NOTE: This option is presently ignored if
SchedulerType=sched/wiki or SchedulerType=sched/wiki2.
--no-requeue
Specifies that the batch job should not be requeued after node
failure. Setting this option will prevent system administrators
from being able to restart the job (for example, after a
scheduled downtime). 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 that 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. Masks will
automatically be generated to bind the tasks to specific core
unless --cpu_bind=none is specified. NOTE: This option is not
supported unless SelectTypeParameters=CR_Core or
SelectTypeParameters=CR_Core_Memory is configured.
--ntasks-per-socket=<ntasks>
Request that 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. Masks will
automatically be generated to bind the tasks to specific sockets
unless --cpu_bind=none is specified. NOTE: This option is not
supported unless SelectTypeParameters=CR_Socket or
SelectTypeParameters=CR_Socket_Memory is configured.
--ntasks-per-node=<ntasks>
Request that ntasks be invoked on each 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.
-O, --overcommit
Overcommit resources. Normally, sbatch will allocate one task
per processor. By specifying --overcommit you are explicitly
allowing more than one task per processor. However no more than
MAX_TASKS_PER_NODE tasks are permitted to execute per node.
-o, --output=<filename pattern>
Instruct SLURM to connect the batch script’s standard output
directly to the file name specified in the "filename pattern".
See the --input option 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.
-p, --partition=<partition name>
Request a specific partition for the resource allocation. If
not specified, the default behaviour is to allow the slurm
controller to select the default partition as designated by the
system administrator.
--propagate[=rlimits]
Allows users to specify which of the modifiable (soft) resource
limits to propagate to the compute nodes and apply to their
jobs. If rlimits is not 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
AS The maximum address space for a processes
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
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, --quiet
Suppress informational messages from sbatch. Errors will still
be displayed.
--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.
--requeue
Specifies that the batch job should be requeued after node
failure. 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, --share
The job allocation can share nodes with other running jobs.
(The default shared/exclusive behaviour depends on system
configuration.) This may result the allocation being granted
sooner than if the --share option was not set and allow higher
system utilization, but application performance will likely
suffer due to competition for resources within a node.
--signal=<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 integer value between zero
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.
-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 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. 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".
--tasks-per-node=<n>
Specify the number of tasks to be launched per node. Equivalent
to --ntasks-per-node.
--tmp=<MB>
Specify a minimum amount of temporary disk space.
-u, --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.
-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 node names. The list may be
specified as a comma-separated list of node names, or a range of
node names (e.g. mynode[1-5,7,...]). 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.
--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.
The following options support Blue Gene systems, but may be applicable
to other systems as well.
--blrts-image=<path>
Path to blrts image for bluegene block. BGL only. Default from
blugene.conf if not set.
--cnload-image=<path>
Path to compute node image for bluegene block. BGP only.
Default from blugene.conf if not set.
--conn-type=<type>
Require the partition connection type to be of a certain type.
On Blue Gene the acceptable of type are MESH, TORUS and NAV. If
NAV, or if not set, then SLURM will try to fit a TORUS else
MESH. You should not normally set this option. SLURM will
normally allocate a TORUS if possible for a given geometry. If
running on a BGP system and wanting to run in HTC mode (only for
1 midplane and below). You can use HTC_S for SMP, HTC_D for
Dual, HTC_V for virtual node mode, and HTC_L for Linux mode.
-g, --geometry=<XxYxZ>
Specify the geometry requirements for the job. The three numbers
represent the required geometry giving dimensions in the X, Y
and Z directions. For example "--geometry=2x3x4", specifies a
block of nodes having 2 x 3 x 4 = 24 nodes (actually base
partitions on Blue Gene).
--ioload-image=<path>
Path to io image for bluegene block. BGP only. Default from
blugene.conf if not set.
--linux-image=<path>
Path to linux image for bluegene block. BGL only. Default from
blugene.conf if not set.
--mloader-image=<path>
Path to mloader image for bluegene block. Default from
blugene.conf if not set.
-R, --no-rotate
Disables rotation of the job’s requested geometry in order to
fit an appropriate partition. By default the specified geometry
can rotate in three dimensions.
--ramdisk-image=<path>
Path to ramdisk image for bluegene block. BGL only. Default
from blugene.conf if not set.
--reboot
Force the allocated nodes to reboot before starting the job.
INPUT ENVIRONMENT VARIABLES
Upon startup, sbatch will read and handle the options set in the
following environment variables. Note that environment variables will
override any options set in a batch script, and command line options
will override any environment variables.
SBATCH_ACCOUNT Same as -A, --account
SBATCH_ACCTG_FREQ Same as --acctg-freq
SLURM_CHECKPOINT Same as --checkpoint
SLURM_CHECKPOINT_DIR Same as --checkpoint-dir
SBATCH_CONN_TYPE Same as --conn-type
SBATCH_CPU_BIND Same as --cpu_bind
SBATCH_DEBUG Same as -v, --verbose
SBATCH_DISTRIBUTION Same as -m, --distribution
SBATCH_EXCLUSIVE Same as --exclusive
SLURM_EXIT_ERROR Specifies the exit code generated when a SLURM
error occurs (e.g. invalid options). This can be
used by a script to distinguish application exit
codes from various SLURM error conditions.
SBATCH_GEOMETRY Same as -g, --geometry
SBATCH_IMMEDIATE Same as -I, --immediate
SBATCH_JOBID Same as --jobid
SBATCH_JOB_NAME Same as -J, --job-name
SBATCH_MEM_BIND Same as --mem_bind
SBATCH_NETWORK Same as --network
SBATCH_NO_REQUEUE Same as --no-requeue
SBATCH_NO_ROTATE Same as -R, --no-rotate
SBATCH_OPEN_MODE Same as --open-mode
SBATCH_OVERCOMMIT Same as -O, --overcommit
SBATCH_PARTITION Same as -p, --partition
SBATCH_QOS Same as --qos
SBATCH_SIGNAL Same as --signal
SBATCH_TIMELIMIT Same as -t, --time
OUTPUT ENVIRONMENT VARIABLES
The SLURM controller will set the following variables in the
environment of the batch script.
BASIL_RESERVATION_ID
The reservation ID on Cray systems running ALPS/BASIL only.
SLURM_CPU_BIND
Set to value of the --cpu_bind option.
SLURM_JOB_ID (and SLURM_JOBID for backwards compatibility)
The ID of the job allocation.
SLURM_JOB_CPUS_PER_NODE
Count of processors available to the job on this node. Note the
select/linear plugin allocates entire nodes to jobs, so the
value indicates the total count of CPUs on the node. The
select/cons_res plugin allocates individual processors to jobs,
so this number indicates the number of processors on this node
allocated to the job.
SLURM_JOB_DEPENDENCY
Set to value of the --dependency option.
SLURM_JOB_NAME
Name of the job.
SLURM_JOB_NODELIST (and SLURM_NODELIST for backwards compatibility)
List of nodes allocated to the job.
SLURM_JOB_NUM_NODES (and SLURM_NNODES for backwards compatibility)
Total number of nodes in the job’s resource allocation.
SLURM_MEM_BIND
Set to value of the --mem_bind option.
SLURM_TASKS_PER_NODE
Number of tasks to be initiated on each node. Values are comma
separated and in the same order as SLURM_NODELIST. If two or
more consecutive nodes are to have the same task count, that
count is followed by "(x#)" where "#" is the repetition count.
For example, "SLURM_TASKS_PER_NODE=2(x3),1" indicates that the
first three nodes will each execute three tasks and the fourth
node will execute one task.
MPIRUN_NOALLOCATE
Do not allocate a block on Blue Gene systems only.
MPIRUN_NOFREE
Do not free a block on Blue Gene systems only.
SLURM_NTASKS_PER_CORE
Number of tasks requested per core. Only set if the
--ntasks-per-core option is specified.
SLURM_NTASKS_PER_NODE
Number of tasks requested per node. Only set if the
--ntasks-per-node option is specified.
SLURM_NTASKS_PER_SOCKET
Number of tasks requested per socket. Only set if the
--ntasks-per-socket option is specified.
SLURM_RESTART_COUNT
If the job has been restarted due to system failure or has been
explicitly requeued, this will be sent to the number of times
the job has been restarted.
SLURM_SUBMIT_DIR
The directory from which sbatch was invoked.
MPIRUN_PARTITION
The block name on Blue Gene systems only.
EXAMPLES
Specify a batch script by filename on the command line. The batch
script specifies a 1 minute time limit for the job.
$ cat myscript
#!/bin/sh
#SBATCH --time=1
srun hostname |sort
$ sbatch -N4 myscript
salloc: Granted job allocation 65537
$ cat slurm-65537.out
host1
host2
host3
host4
Pass a batch script to sbatch on standard input:
$ sbatch -N4 <<EOF
> #!/bin/sh
> srun hostname |sort
> EOF
sbatch: Submitted batch job 65541
$ cat slurm-65541.out
host1
host2
host3
