awsbsub - AWS ParallelCluster


Submits jobs to the cluster’s job queue.

awsbsub [-h] [-jn JOB_NAME] [-c CLUSTER] [-cf] [-w WORKING_DIR] [-pw PARENT_WORKING_DIR] [-if INPUT_FILE] [-p VCPUS] [-m MEMORY] [-e ENV] [-eb ENV_DENYLIST] [-r RETRY_ATTEMPTS] [-t TIMEOUT] [-n NODES] [-a ARRAY_SIZE] [-d DEPENDS_ON] [command] [arguments [arguments ...]]

Positional Arguments


Submits the job (the command specified must be available on the compute instances), or specifies the file name to be transferred (also see the --command-file option).


(Optional) Specifies arguments for the command or the command-file.

Named Arguments

-jn JOB_NAME, --job-name JOB_NAME

Names the job. The first character must be alphanumeric. The job name can contain up to 128 characters. Letters (both uppercase and lowercase), numbers, hyphens, and underscores are allowed.

-c CLUSTER, --cluster CLUSTER

Specifies the cluster to use.

-cf, --command-file

Indicates that the command is a file to be transferred to the compute instances.

Default: False

-w WORKING_DIR, --working-dir WORKING_DIR

Specifies the folder to use as the job's working directory. If a working directory is not specified, the job is executed in the job-<AWS_BATCH_JOB_ID> subfolder of the user’s home directory. You can use either this parameter or the --parent-working-dir parameter.


Specfies the parent folder of the job's working directory. If a parent working directory is not specified, it defaults to the user’s home directory. A subfolder named job-<AWS_BATCH_JOB_ID> is created in the parent working directory. You can use either this parameter or the --working-dir parameter.

-if INPUT_FILE, --input-file INPUT_FILE

Specifies the file to be transferred to the compute instances, in the job's working directory. You can specify multiple input file parameters.

-p VCPUS, --vcpus VCPUS

Specifies the number of vCPUs to reserve for the container. When used together with –nodes, it identifies the number of vCPUs per node.

Default: 1

-m MEMORY, --memory MEMORY

Specifies the hard limit of memory (in MiB) to provide for the job. If your job attempts to exceed the memory limit specified here, the job is killed.

Default: 128

-e ENV, --env ENV

Specifies a comma-separated list of environment variable names to export to the job environment. To export all environment variables, specify ‘all’. Note that a list of 'all' environment variables will not include those listed in the –env-blacklist parameter, or variables starting with the PCLUSTER_* or AWS_* prefix.

-eb ENV_DENYLIST, --env-blacklist ENV_DENYLIST

Specifies a comma-separated list of environment variable names to not export to the job environment. By default, HOME, PWD, USER, PATH, LD_LIBRARY_PATH, TERM, and TERMCAP are not exported.


Specifies the number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than 1, the job is retried if it fails, until it has moved to RUNNABLE that specified number of times.

Default: 1

-t TIMEOUT, --timeout TIMEOUT

Specifies the time duration in seconds (measured from the job attempt’s startedAt timestamp) after which AWS Batch terminates your job if it has not finished. The timeout value must be at least 60 seconds.

-n NODES, --nodes NODES

Specifies the number of nodes to reserve for the job. Specify a value for this parameter to enable multi-node parallel submission.


Multi-node parallel jobs are not supported when the cluster_type parameter is set to spot.

-a ARRAY_SIZE, --array-size ARRAY_SIZE

Indicates the size of the array. You can specify a value between 2 and 10,000. If you specify array properties for a job, it becomes an array job.

-d DEPENDS_ON, --depends-on DEPENDS_ON

Specifies a semicolon-separated list of dependencies for a job. A job can depend upon a maximum of 20 jobs. You can specify a SEQUENTIAL type dependency without specifying a job ID for array jobs. A sequential dependency allows each child array job to complete sequentially, starting at index 0. You can also specify an N_TO_N type dependency with a job ID for array jobs. An N_TO_N dependency means that each index child of this job must wait for the corresponding index child of each dependency to complete before it can begin. The syntax for this parameter is "jobId=<string>,type=<string>;...".
