SLURM Jobscript

The following jobscript needs to be submitted from /scratch/$USER directory. This is imaprative because /home directory is not mounted on compute nodes. Also /project directory is read-only on compute node.

Change directory to /scratch, copy the jobscript below and paste it in a file named e.g. jobscript.slurm

#!/bin/bash
#SBATCH --time=00:10:00
#SBATCH --nodes=1
#SBATCH --ntasks=32
#SBATCH --hint=nomultithread

srun -n ${SLURM_NTASKS} --hint=nomultithread /bin/hostname

The above jobscript can now be submitted using the sbatch command.

sbatch jobscript.slurm

KSL has written a convinient utility called Jobscript Generator. Use this template to create a jobscript and copy-paste it in a file in your SSH terminal on Shaheen, Ibex or Neser login nodes.

If you get an error in regarding account specifcation, please email helpdesk with the your username and error and the jobscript.
