Example Slurm Job Script

 

This is an example slurm job script for the Ookami short queue:

#!/usr/bin/env bash

#SBATCH --job-name=examplejob
#SBATCH --output=examplejob.log
#SBATCH --ntasks-per-node=48
#SBATCH -N 2
#SBATCH --time=00:05:00
#SBATCH -p short

module load slurm
module load CPE
module load cray-mvapich2_nogpu_svealpha/2.3.4

mpicc /lustre/projects/global/samples/HelloWorld/mpi_hello.c -o mpi_hello

srun ./mpi_hello

This job will utilize 2 nodes, with 48 CPUs per node for 5 minutes in the short partition to compile and run an mpi_hello script.

If we named this  script "test.slurm", we could submit the job  using the following command:

sbatch test.slurm

Breakdown:

The directive 

#SBATCH -p short

indicates to the batch scheduler that you want to use the short queue.

The directives 

#SBATCH --ntasks-per-node=48
#SBATCH --nodes=2
#SBATCH --time=05:00

indicate that we are requesting 2 nodes, and we will run 48 tasks per node for 5 minutes.

All of these directives are passed straight to the sbatch command, so for a full list of options just take a look at the sbatch manual page by issuing the command:

man sbatch
