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


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


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.


-b, --batch
Signal the batch job shell and its child processes. This is not applicable if step_id is specified. NOTE: The shell itself may exit upon receipt of many signals. You may avoid this by explicitly trap signals within the shell script (e.g. "trap <arg> <signals>"). See the shell documentation for details.
Send the job signal request to the slurmctld daemon rather than directly to the slurmd daemons. This increases overhead, but offers better fault tolerance.
Print a help message describing all scancel options.
-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. If no signal is specified, the specified job or step will be terminated.
-t, --state=job_state_name
The state of the jobs 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.
Print a brief help message listing the scancel options.
-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 scancel command.
The Slurm job ID to be signaled.
The step ID of the job step to be signaled. If not specified, the operation is performed at the level of a job. When --batch is used, the batch shell processes will be signaled. Otherwise the processes associated with all job steps, but not the batch script itself, will be signaled.


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)

-b, --batch
-i, --interactive
-n, --name=job_name
-p, --partition=partition_name
-t, --state=job_state_name
-u, --user=user_name
-v, --verbose
The location of the SLURM configuration file.


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.


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
Send SIGUSR1 to the batch shell processes of job 1235:
scancel --signal=USR1 --batch 1235
Cancel job all pending jobs belonging to user "bob" in partition "debug":
scancel --state=PENDING --user=bob --partition=debug
