SLURM Demo

From Stat DS Computing Wiki

This page will walk you through submitting a job using SLURM. It will also cover basic Linux usage.

Copy SLURM Demo Files

Log in to the head node server using your StatDS computing account through your terminal. (If you forget your password, reset it here.) This cluster is used for demonstration purposes only. Actual compute jobs are not meant to be submitted to this cluster.

ssh statdsuser@ood.stat.cmu.edu

Copy the SLURM Demo folder to your home directory. Do not run these files without moving them to your own working directory.

cp -r /share/slurmdemo ~/slurmdemo

Navigate to your new SLURM Demo directory.

cd ~/slurmdemo

View the contents of the SLURM Demo directory.

ls -l

Submit SLURM Job

Modify the “submit_bash.sh” script

You may use any text editor (vim, vi, nano, etc). In this example nano will be used.

nano submit_bash.sh

Change these three lines and make them more specific to you.

SBATCH --job-name=yourjobuniquename This is the name of your job.

SBATCH --output=yourjoboutputfile_%j.out This is the name of your job’s output file. Any intentional output generated from your job will be placed into this file. The “%j” will add the job’s unique JobID to the name.

SBATCH --error=yourjoberrorfile_%j.err This is the name of your job’s error file. Any unintentional errors generated in the script will be placed into this file. The “%j” will add the job’s unique JobID to the name.

Run the submit script

sbatch submit_bash.sh

squeue

View the output file once the script is finished (use your unique outfile name)
