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 scholar job1 myusername R 20:19 1 scholar-a000
185841 scholar job2 myusername R 20:19 1 scholar-a001
185844 scholar job3 myusername R 20:18 1 scholar-a002
185847 scholar job4 myusername R 20:18 1 scholar-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
andStderr
are the locations of stdout and stderr of the job, respectively.Reason
will show why aPENDING
job isn't running. The above error says that it has been requested to start at a specific, later time.
