Introduction

Before going any further, consider using GNU Octave instead of MATLAB for all but the most demanding or vendor-specific tasks:

  • To start octave:
octave

Licensing

MATLAB is available on Carbon on request, and is subject to strictly limited license terms. Running MATLAB is restricted to:

  • Argonne employees (including consultants and students),
  • on node clogin5 only,
  • by one user at a time,
  • not remotely, except for a certain number of users per year.

Toolboxes

We have the following toolboxes installed:

  • Curve_Fitting_Toolbox
  • Image_Toolbox
  • Optimization_Toolbox
  • Distrib_Computing_Toolbox
  • Statistics_Toolbox

Request access

To request access to MATLAB on Carbon, send an email.

Running MATLAB

  • To get started, load the "matlab" module as described at HPC/Module Setup.
  • Then choose how to run the application:
GUI
matlab
Command line
For basic calculations, you could save some startup time by simply using the text interface.
matlab -nojvm

Troubleshooting

Access

To run MATLAB on Carbon, you must be a member of the "matlab" group. You could still load the "matlab" module if you are not, but it will not enable anything.

  • To inspect your current group membership, run:
groups
The word "matlab" must show.

Running on a host that is not licensed

License checkout failed.
License Manager Error -9
The hostid of your computer ("001122334455 001122334466") does not match the hostid of the license file (001122334400).

Solution: log in to clogin5 and retry. If you use the Mega SSH gateway, review the updated instructions for Linux/Mac/Cygwin or PuTTY on Windows on how to configure and use port forwarding to reach a specific login node.

License in use

License checkout failed.
License Manager Error -9
This error may occur when:
-The hostid of this computer does not match the hostid in the license file.
-A Designated Computer installation is in use by another user.
If no other user is currently running MATLAB, you may need to activate.

Solution: Send a support request.
