Monitoring the Job

Once a job is submitted there are several commands you can use to monitor the progress of the job.

To see your jobs, use the squeue -u command and specify your username:

(Remember, in our SLURM environment a queue is referred to as an 'Account')

squeue -u myusername

    JOBID   ACCOUNT    NAME    USER   ST    TIME   NODES  NODELIST(REASON)
   182792   standby    job1    myusername    R   20:19       1  negishi-a000
   185841   standby    job2    myusername    R   20:19       1  negishi-a001
   185844   standby    job3    myusername    R   20:18       1  negishi-a002
   185847   standby    job4    myusername    R   20:18       1  negishi-a003

To retrieve useful information about your queued or running job, use the scontrol show job command with your job's ID number. The output should look similar to the following:

There are several useful bits of information in this output.

  • JobState lets you know if the job is Pending, Running, Completed, or Held.

  • RunTime and TimeLimit will show how long the job has run and its maximum time.

  • SubmitTime is when the job was submitted to the cluster.

  • NumNodes, NumCPUs, NumTasks and CPUs/Task are the number of Nodes, CPUs, Tasks, and - CPUs per Task are shown.

  • WorkDir is the job's working directory.
