Last update: January 15, 2020
Mathwork's MATLAB is installed and supported at TACC and is available on the following TACC resources: Frontera, Stampede2, Lonestar5, and Maverick2.
MathWork's agreement with the University of Texas now allows TACC and XSEDE users to access MATLAB for non-commercial, academic use. If you would like access to MATLAB submit a help desk ticket through either the TACC or XSEDE portal. 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.
Running MATLAB in 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 modules on the TACC resources. Before you launch MATLAB load the MATLAB module with the following command:
login1$ module load matlabYou 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
IMPORTANT: 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.
Running MATLAB in Batch Mode
You can also submit your MATLAB job to the batch nodes (compute nodes) on the TACC resources, e.g. Frontera, Stampede2, Lonestar5, or Maverick2. 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
#!/bin/bash #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

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.
Mat=zeros(100,1); parfor i = 1:100 Mat(i) = i*i; end
if (matlabpool('size') ) == 0 matlabpool(12); else matlabpool close; matlabpool(12); end
Consult the MATLAB Parallel Toolbox documentation for detailed descriptions and advanced features.

MATLAB is a commercial product of MathWorks. Please solicit help from Mathworks regarding MATLAB code. If you need any further assistance related to access issues or running issues, contact TACC via the XSEDE User Portal if you are an XSEDE user. All other users request help via the TACC User Portal.
