Submit job:

sbatch sample.sub

The job’s status in the queue can be monitored with squeue; (add -u username to focus on a particular user’s jobs).

The job can be deleted with scancel <job_id> .

When the job finishes (in error or correctly) there will normally be one file created in the submission directory with the name of the form slurm-NNNN.out (where NNNN is the job id).
