Last update: June 8, 2023

Mathwork's MATLAB is installed and supported at TACC and is available on the following TACC resources: Frontera, Stampede2 and Lonestar6.


MathWork's agreement with the University of Texas now allows TACC users to access MATLAB for non-commercial, academic use. If you would like access to MATLAB submit a help desk ticket. Include in your ticket your institutional affiliation and a brief statement confirming that you will use MATLAB only for non-commercial, academic purposes. If you are affiliated with the University of Texas, include your academic department in your help desk ticket.

If you have your own network licenses for toolboxes that are not available through the University of Texas, we can help you configure these licenses on TACC systems. Again, submit a help desk ticket for assistance.

Interactive Mode

MATLAB is normally launched with the MATLAB Desktop UI and used in interactive mode. Create a VNC session following the directions in the Remote Desktop Access section.

MATLAB is managed under the modules system on the TACC resources. Before you launch MATLAB load the MATLAB module with the following command:

login1$ module load matlab

You can always get the MATLAB help information by typing the following module help command.

login1$ module help matlab

The following figure shows how MATLAB is launched inside the VNC session.

Figure 1. MATLAB launched in a VNC session



Do NOT launch MATLAB on the login nodes. This may fail and, more importantly, it will prevent other users from doing their work, as your execution will take up too many cycles on the shared login node. Using MATLAB on the login nodes is considered system abuse, and will be treated as such. See TACC usage policies.

Batch Mode

You can also submit your MATLAB job to the batch nodes (compute nodes) on the TACC resources, e.g. Frontera, Stampede2, or Lonestar6. To do so, 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 Stampede2 job script below.

Example 1. Sample MATLAB job script to run on Stampede2

#SBATCH -J matlabjob              # job name
#SBATCH -e matlabjob.%j.err       # error file name 
#SBATCH -o matlabjob.%j.out       # output file name 
#SBATCH -N 1                      # request 1 node
#SBATCH -n 16                     # request all 16 cores 
#SBATCH -t 01:00:00               # designate max run time 
#SBATCH -A myproject              # charge job to myproject 
#SBATCH -p skx-normal             # designate queue 

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

Then submit the job to the scheduler in the standard way. See the Running Jobs section in the respective user guides

Resource Submit a batch job
Frontera login1$ sbatch myjobscript
Stampede2 login1$ sbatch myjobscript
Lonestar6 login1$ sbatch myjobscript

Parallel MATLAB

The parallel computing toolbox is available on the TACC resources as well. Our MathWorks Total Academic Headcount (TAH) license for the UT-Austin campus does not include MATLAB Distributed Computing Server. Therefore, multi-node parallel operations are not supported.

The following two examples demonstrate parallel operations using the parfor and matlabpool functions. Here are the basic examples.

Example 2. MATLAB parfor

parfor i = 1:100
    Mat(i) = i*i;

Example 3. MATLAB matlabpool

if (matlabpool('size') ) == 0 
    matlabpool close;

Consult the MATLAB Parallel Toolbox documentation for detailed descriptions and advanced features.
