sbatch(1)

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>
    When the task/affinity plugin is enabled, specifying an allocation in this manner also instructs SLURM to use a CPU affinity mask to guarantee the request is filled as specified. NOTE: Support for these options are configuration dependent. The task/affinity plugin must be configured. In addition either select/linear or select/cons_res plugin must be configured. If select/cons_res is configured, it must have a parameter of CR_Core, CR_Core_Memory, CR_Socket, or CR_Socket_Memory.

--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 that case that 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, us 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

    memory_bound
        Select settings for memory bound applications: use only one core in each socket

    [no]multithread
        [don't] use extra threads with in-core multi-threading which can benefit communication intensive applications

        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 socket or core (depending upon the value of the SelectTypeParameters parameter in slurm.conf), 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. Both sig_time and sig_num must have integer values 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.
--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=<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

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.
