How to check whether your job is running
To check the job status of all your jobs, you can use squeue, i.e. by executing:
squeue -u MyUsername
You can also get a quick view of the status of a job
squeue -j JobId
JobId is the job id number that
sbatch returns. To see more
details about a job, use
scontrol show job JobId
Both commands will show the job state (ST), and can show a job reason for why a job is pending. Job States describes a few of the more common ones.
sstat -j JobId sacct -j JobId
sacct have an option
--format to select which
fields to show. See the documentation of the commands for the
available fields and what they mean.
When a job has finished, the output file
contain some usage statistics from
Cancelling jobs and putting jobs on hold
You can cancel running or pending (waiting) jobs with scancel. For instance:
scancel JobId # Cancel job with id JobId (as returned from sbatch) scancel --user=MyUsername # Cancel all your jobs scancel --account=MyProject # Cancel all jobs in MyProject
The command scontrol can be used to further control pending or running jobs:
scontrol requeue JobId: Requeue a running job. The job will be stopped, and its state changed to pending.
scontrol hold JobId: Hold a pending job. This prevents the queue system from starting the job. The job reason will be set to
scontrol release JobId: Release a held job. This allows the queue system to start the job.
It is also possible to submit a job and put it on hold immediately
sbatch --hold JobScript.
