Creating the Submission Script

To submit work to a SLURM queue, you must first create a job submission file. This job submission file is essentially a simple shell script. It will set any required environment variables, load any necessary modules, create or modify files and directories, and run any applications that you need:

#!/bin/bash
# FILENAME:  myjobsubmissionfile

# Loads Matlab and sets the application up
module load matlab

# Change to the directory from which you originally submitted this job.
cd $SLURM_SUBMIT_DIR

# Runs a Matlab script named 'myscript'
matlab -nodisplay -singleCompThread -r myscript

Job Script Environment Variables

SLURM sets several potentially useful environment variables which you may use within your job submission files. Here is a list of some:

Name	Description
SLURM_SUBMIT_DIR	Absolute path of the current working directory when you submitted this job
SLURM_JOBID	Job ID number assigned to this job by the batch system
SLURM_JOB_NAME	Job name supplied by the user
SLURM_JOB_NODELIST	Names of nodes assigned to this job
SLURM_CLUSTER_NAME	Name of the cluster executing the job
SLURM_SUBMIT_HOST	Hostname of the system where you submitted this job
SLURM_JOB_PARTITION	Name of the original queue to which you submitted this job
