MULTIPLE JOB SUBMISSION

There are many times when users may need to execute their programs multiple times, particularly when random number generation is being used.

Some general notes:

• The variable $SLURM_SUBMIT_DIR indicates the directory where the Slurm script file is located and launched from.
• The program executable hello.exe is a simple “Hello World” program and can be replaced with your own executable files.
• The “email user” section within the Slurm submission has been purposely removed – as you don’t want to have 10 emails sent to you each time you run this script.
• You can change the number of times you would like the program to execute by simple changing the “for ((i=1; i<=10; i+=1))” and replacing the 10 value with a value of your choice.
• The “jobname” will be set to Multi-Job_[$1], where $1 is the job number.  You may wish to change the jobname to something different.

The details for this script can be found below:

multi-submit.slurm

#!/bin/bash

for ((i=1; i<=10; i+=1))
do
    jobname=Multi-Job_$i
    cat << EOF | sbatch
