MATLAB
- Stephen Kolmann
Matlab is available on Artemis. It is best suited for workloads that can be submitted as non-interactive “batch” jobs.
The following versions of Matlab are installed on Artemis:
- R2013a
- R2014b (default)
- R2015b
- R2016b
- R2017a
- R2017b
- R2018a
- R2018b
- R2019a
- R2019b
- R2020a
You will need to load the relevant version of Matlab you want to use, see the loading modules guide for more information.
If you would like a newer version of Matlab to be installed, you can submit a High Performance Computing request via the Services Portal.
Example MATLAB script
An example single core Matlab script is below:
#!/bin/bash
#PBS -P <Project>
#PBS -l select=1:ncpus=1:mem=4gb
#PBS -l walltime=4:00:00
module load matlab/R2018a
cd "${PBS_O_WORKDIR}"
matlab -nosplash -nodisplay -r "matlab_script" > matlab_output.log
Parallel Matlab jobs
If you have a Matlab program that can run in parallel (using more than one CPU or core), use the following script to run your Matlab program on Artemis:
#!/bin/bash
#PBS -P <Project>
#PBS -l select=1:ncpus=4:mpiprocs=4:mem=4gb
#PBS -l walltime=4:00:00
module load matlab/R2018a
cd "${PBS_O_WORKDIR}"
matlab -nosplash -nodisplay -r "matlab_script" > matlab_output.log
Make sure the number of mpiprocs matches the number of CPUs requested.
If you are interested in writing parallel Matlab scripts, see the Mathworks Parallel Computing Toolbox guide.
