Matlab

Mathworks Matlab is available on our HPC facilities as part of our University licensing agreement. It is available to all users.

Check Versions

$ module avail MATLAB

------------------------------------------------------------ /mnt/storage/apps/eb/modules/all ------------------
   MATLAB/2017a    MATLAB/2018b    MATLAB/2020a    MATLAB/2022b    MATLAB/2024a (D)

  Where:
   D:  Default Module
$

The actual versions displayed may vary depending on which HPC facility you are using. Use the module avail command, as above, to determine which versions are present.

Running

Open OnDemand Application

This section is incomplete

This documentation section is still being written and will not be available until Comet is in production.

Interactive Desktop GUI

Interactive via the Matlab desktop interface (you must have enabled X11 over SSH in your client):

$ module load MATLAB
$ matlab

Matlab will load the desktop interface/window and, assuming you have correctly configured your X11 over SSH settings, this should be displayed on your desktop:

Command Line

Run Matlab in command line mode, without the desktop application window:

$ module load MATLAB
$ matlab -nodesktop -nosplash
MATLAB is selecting SOFTWARE rendering.

Tips

Matlab Home Directory Use

When running Matlab on the HPC it will create an entirely new, host-specific preference directory within your .MathWorks/ServiceHost folder in your home directory. Since you may end up running Matlab on many dozens of different hosts via Slurm, this can end up taking up many gigabytes of your home directory space:

$ cd $HOME
$ cd .MathWorks/ServiceHost
$ du -h -s *
950M	login01/
898M	login02/
1023M	sb085/
1291M	sb090/
1407M	sb091/
789M	sb099/
$

It is safe to delete these directories, as they will be recreated again the next time you run Matlab on another host.

Initial discussion of large, per-host ServiceHost folders reported on the Mathworks support forum:
