Creating Your First Sbatch Script

1. Create a directory for slurm batch or sbatch scripts

   mkdir -p ~/scripts
   cd ~/scripts
   

2. Create and edit your sbatch script

   vi hello_world.sh
   

3. Example sbatch script

   #!/bin/bash
   #SBATCH --job-name=hello_world       # Job name
   #SBATCH --output=hello_world.out     # Standard output file
   #SBATCH --error=hello_world.err      # Standard error file
   #SBATCH --partition=cpu              # Partition to submit to
   #SBATCH --qos=normal                 # Define QoS (Quality of Service)
   #SBATCH --ntasks=1                   # Number of tasks
   #SBATCH --cpus-per-task=1            # Number of CPU cores per task
   #SBATCH --mem=1G                     # Memory per node
   #SBATCH --time=00:10:00              # Walltime (HH:MM:SS)
   
   
   # Your commands go below
   echo "Hello, Cluster!"

Info

For production or large jobs, always load modules inside your Slurm script using module load so that the compute nodes have the correct environment. For more details, refer to Software Environment & Modules
