How to use array jobs in SLURM

General

Job arrays in SLURM allow you to run many jobs using one and same job script. The job script you submit with the sbatch command does not accept any parameters. Like this:

$ sbatch array_job.slurm

An array job script example, array_job.slurm:

#!/bin/bash
# ============================================
#SBATCH --job-name=my_array_job
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=1
#SBATCH --mem=4gb
#SBATCH --time=0-01:00:00
#SBATCH --array=1-10

# ============================================
