MATLAB License Policy

In order to effectively utilize the limited number of MATLAB licenses on NAS-supported workstations or supercomputing systems:

Each user is limited to a single interactive MATLAB license.
When using the MATLAB GUI, after four hours of being idle and not running a job, the license will be revoked.
Start a second MATLAB GUI on the same host to compile or use toolboxes. Exit the second GUI when you are done with the license to immediately free up the compiler/toolbox license.
If users are waiting for licenses, a MATLAB process that has been idle for more than ten minutes may be terminated to revoke its license and make it available to another user.

For more information, including alternatives to using MATLAB licenses, see Using NAS MATLAB Licenses.
