#SBATCH --output=test-serial_%N_%j.out
# STDERR file; "N" is node number and "j" job id number
#SBATCH --error=test-serial_%N_%j.err
# Number of processes
#SBATCH --ntasks=64
# Memory requirement per CPU
#SBATCH --mem-per-cpu=3
# Total wall-time
#SBATCH --time=00:05:00

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 a name of the form slurm-NNNN.out (where NNNN is the job id).
