SLURM Jobscript

The following jobscript needs to be submitted from /scratch/$USER directory. This is imperative 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

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