or

module load matlab

How to submit a job#

Serial Job#

Below is an example job, requesting a single CPU core and 2 GB of memory.

#!/bin/bash
#SBATCH --job-name=simple_matlab_job
#SBATCH --time=00:30:00
#SBATCH --mem=2G
#SBATCH --output=/path/to/output/file

module load matlab

# Run the job
matlab input_script.m

Parallel Job#

An example job, requesting 16 CPU cores.

#!/bin/bash
#SBATCH --job-name=simple_threaded_job
#SBATCH --time=05:00:00
#SBATCH --nodes=1
#SBATCH --ntasks=1          
#SBATCH --cpus-per-task=16  # Number of CPU cores required
#SBATCH --output=/path/to/output/file

module load matlab/R2023a

# Run the job
matlab input_script.m

Interactive Usage#

Some software can be launched interactively on either the login or compute nodes. Users should never run computationally intensive jobs on the login node; it is only for quick testing. We recommend using the srun command to run interactive jobs on the compute nodes.

The below example shows an interactive session, requesting 30 minutes of time with 4 CPUs then loading and launching the MATLAB interpreter.

[username@login1[aire] ~]$ srun -t 00:30:00 --nodes=1 --ntasks=1 --cpus-per-task=4 --pty /bin/bash
[username@node048[aire] ~]$ module load matlab
[username@node048[aire] ~]$ matlab
