SLURM Usage Guide

This document provides a clean, modular reference for basic SLURM usage, including writing a job script, submitting jobs, checking job status, and deleting jobs.

1. Basic SLURM Job Script

A minimal example job script (job.sh) using 10 CPUs:

#!/bin/bash
#SBATCH --job-name=myjob
#SBATCH --error=myjob_%j.err
#SBATCH --time=01:00:00
#SBATCH --partition=compute
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=10

# Load modules as required
# module load <executable>

# Run your program
./<executable> <file>

2. Submitting a Job

Submit a SLURM job using sbatch:

sbatch job.sh

SLURM will return a job ID, for example:

Submitted batch job 123456

3. Checking Job Status

Use squeue to check the status of your job:

squeue -j <jobid>

Example:

squeue -j 123456

You can also see all your jobs:

squeue -u $USER

4. Deleting / Canceling a Job

To cancel a job that is queued or running:

scancel <jobid>

Example:

scancel 123456

5. Additional Useful Commands

• View detailed job information:

sacct -j <jobid>
