Inspecting and Modifying SLURM Jobs

Most of the actions that modify the jobs will require root to do them.

Getting detailed information about a running job

scontrol show job <JOB_ID>

This will dump detailed job properties (attributes). Example: (output shortened)

$ scontrol show job 1207296
JobId=1207296 JobName=sys/dashboard/sys/jupyter
   UserId=wpurwant(449753) GroupId=users(14514) MCS_label=N/A
   Priority=19288 Nice=0 Account=odu QOS=normal
   JobState=RUNNING Reason=None Dependency=(null)
   Requeue=0 Restarts=0 BatchFlag=1 Reboot=0 ExitCode=0:0
   RunTime=23:16:02 TimeLimit=1-00:00:00 TimeMin=N/A
   SubmitTime=2023-01-12T10:51:14 EligibleTime=2023-01-12T10:51:14
   AccrueTime=2023-01-12T10:51:14
   StartTime=2023-01-12T10:51:15 EndTime=2023-01-13T10:51:15 Deadline=N/A
   ...

Modifying job properties

(requires root)

scontrol update jobid=<JOB_ID> <ATTRIBUTE_LIST...>

Example:

# scontrol update jobid=1207296 timelimit=3-0

This will modify the time limit of job number 1207296. The attribute is in the KEY=VALUE format, and the keyword is case-insensitive. See the output of scontrol show job for the complete list of attributes as well as the acceptable format of the values.
