MATLAB (matrix laboratory) is a proprietary programming language developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, and creation of user interfaces.

You can run your Matlab codes on Cypress clusters but you can't use GUI(Graphical User Interface) on computing nodes.

Running MATLAB interactively

Start an interactive session,

[fuji@cypress2 ~]$ idev
Requesting 1 node(s)  task(s) to normal queue of defq partition
1 task(s)/node, 20 cpu(s)/task, 2 MIC device(s)/node
Time: 0 (hr) 60 (min).
Submitted batch job 47343
JOBID=47343 begin on cypress01-063
--> Creating interactive terminal session (login) on node cypress01-063.
--> You have 0 (hr) 60 (min).

Load the module

[fuji@cypress01-063 ~]$ module load matlab

Run MATLAB on the command-line window,

[fuji@cypress01-063 ~]$ matlab
MATLAB is selecting SOFTWARE OPENGL rendering.

You will get to the MATLAB command-line and can run MATLAB code here but no graphics.

Running MATLAB in a batch mode

You can also submit your MATLAB job to the batch nodes (compute nodes) on Cypress. To do so, please first make sure that the MATLAB module has been loaded, and then launch "matlab" with the "-nodesktop -nodisplay -nosplash" option as shown in the sample SLURM job script below.

#SBATCH --qos=normal            # Quality of Service
#SBATCH --job-name=matlab     # Job Name
#SBATCH --time=24:00:00         # WallTime
#SBATCH --nodes=1               # Number of Nodes
#SBATCH --ntasks-per-node=1     # Number of tasks (MPI processes)
#SBATCH --cpus-per-task=1       # Number of threads per task (OMP threads)

module load matlab
matlab -nodesktop -nodisplay -nosplash < mymatlabprog.m
