The majority of Matlab users at the Hutch have Matlab installed on their desktop system. Most users have dedicated licenses for their desktop installs Matlab. Dedicated licenses offer the flexibility to use Matlab with a laptop on or off campus. The center has a limited number of shared network licenses. Users are allowed to use a maximum of 4 concurrent Matlab licenses from the license manager. The shared network licenses can be used with the centers Linux cluster. This document describes how to use Matlab on the
Interactive Matlab on Linux
If you have a Windows or Mac desktop and want to run Matlab interactively on a Linux server, you will need to map the display from Linux to your Windows system. We recommend using noMachine for both display mapping and session management. Do not run Matlab directly from the noMachine servers or from a Rhino. Use grabnode to allocate a cluster node for starting a Matlab session.
- From your Linux session manager, start a terminal.
grabnodeAnswer the questions about how many CPUs and Memory you require. When your
grabnodeis successful you will have a Linux command prompt on a gizmo cluster node.
module load matlab/R2017a
matlaband press enter. The Matlab window should open in your Linux session. Success!
Running Matlab batch jobs on Linux
Matlab programs can be run on the
gizmo cluster. The cluster supports additional resources that are not available to a desktop install.
- Start a terminal session on a
- Your Matlab program and data need to be available to the
- Create a batch script to run your Matlab program

MATLAB Distributed Compute Engine
The distributed compute engine allows you to run parallelized Matlab programs across multiple cores and/or nodes simultaneously. Tutorial and setup guide for the parallel tool box is in the wiki-code-examples repo.
