SCANCEL(1)

NAME
scancel - Used to signal jobs or job steps that are under the control of Slurm.

SYNOPSIS
scancel [OPTIONS...] [job_id[.step_id]] [job_id[.step_id]...]

DESCRIPTION
scancel is used to signal or cancel jobs or job steps. An arbitrary number of jobs or job steps may be signaled using job specification filters or a space separated list of specific job and/or job step IDs. A job or job step can only be signaled by the owner of that job or user root. If an attempt is made by an unauthorized user to signal a job or job step, an error message will be printed and the job will not be signaled.

OPTIONS

--help
    Print a help message describing all scancel options.

--usage
    Print a brief help message listing the scancel options.

-b, --batch
    Signal only the batch job shell.

-i, --interactive
    Interactive mode. Confirm each job_id.step_id before performing the cancel operation.

-n, --name=job_name
    The name of jobs to be signaled.

-p, --partition=partition_name
    The name of the partition from which jobs are to be signaled.

-q, --quiet
    Do not report an error if the specified job is already completed. This option is incompatible with the --verbose option.

-s, --signal=signal_name
    The name or number of the signal to be send. Default value is "KILL".

-t, --state=job_state_name
    The state of the jobs are to be signaled. job_state_name may have a value of either "PENDING", "RUNNING" or "SUSPENDED".

-u, --user=user_name
    The name of the user whose jobs are to be signaled.

-v, --verbose
    Print additional logging. Multiple v's increase logging detail. This option is incompatible with the --quiet option.

-V, --Version
    Print the version number of the scontrol command.

ARGUMENTS

job_id
    The Slurm job ID of the job to have one or more of its steps signaled.

step_id
    The step ID of the job step to be signaled. If none is provided and the --batch option is not used, then all jobs steps associated with the provided job_id will be signaled.

ENVIRONMENT VARIABLES

Some scancel options may be set via environment variables. These environment variables, along with their corresponding options, are listed below. (Note: commandline options will always override these settings)

SCANCEL_BATCH
    -b, --batch

SCANCEL_INTERACTIVE
    -i, --interactive

SCANCEL_NAME
    -n, --name=job_name

SCANCEL_PARTITION
    -p, --partition=partition_name

SCANCEL_STATE
    -t, --state=job_state_name

SCANCEL_USER
    -u, --user=user_name

SCANCEL_VERBOSE
    -v, --verbose

SLURM_CONF
    The location of the SLURM configuration file.

NOTES

If multiple filters are supplied (e.g. --partition and --name) only the jobs satisfying all of the filtering options will be signaled.

If a signal value of "KILL" (the default value) is to be sent to an entire job, this will result in the job's termination and its resource allocation being released.

Cancelling a job step will not result in a job being terminated. The job must be cancelled to release a resource allocation.

EXAMPLES

Send SIGTERM to steps 1 and 3 of job 1234:
    scancel --signal=TERM 1234.1 1234.3

Cancel job 1234 along with all of its steps:
    scancel 1234

Cancel job all pending jobs belonging to user "bob" in partition "debug":
    scancel --state=PENDING --user=bob --partition=debug
