Adding time to a running slurm job

I have a job running a linux machine managed by slurm. Now that the job is running for a few hours I realize that I underestimated the time required for it to finish and thus the value of the --time argument I specified is not enough. Is there a way to add time to an existing running job through slurm?

Solution

  • Use the scontrol command to modify a job

    scontrol update jobid=<job_id> TimeLimit=<new_timelimit>

    Use the SLURM time format, eg. for 8 days 15 hours: TimeLimit=8-15:00:00

    Requires admin privileges, on some machines.

    Will be allowed to users only if the job is not running yet, on most machines.
