Checking Job Status

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  a000
   185841   standby    job2    myusername    R   20:19       1  a001
   185844   standby    job3    myusername    R   20:18       1  a002
   185847   standby    job4    myusername    R   20:18       1  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:

scontrol show job 3519

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.
The job's number of Nodes, Tasks, Cores (CPUs) and CPUs per Task are shown.
WorkDir is the job's working directory.
StdOut and Stderr are the locations of stdout and stderr of the job, respectively.
Reason will show why a PENDING job isn't running. The above error says that it has been requested to start at a specific, later time.
