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
Before you Start
If you want to run Matlab interactively on one of SciComp’s compute nodes you will need to forward the display from that remote system to your desktop. noMachine is the recommended way to do this.
NOTE: Do not run computationally intensive processes on the noMachine systems or the
rhinonodes. Use these only for development, design, and testing. Once your process is designed and tested, plase use the
grabnodecommand to request and allocate a cluster node for your process.
From a terminal in a noMachine session:
grabnode, then answer 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/2019a
matlaband press enter. The Matlab window should open in your Linux session. Success!
Running Matlab Batch Jobs on a Cluster
Matlab programs can be run on the
gizmo cluster using
sbatch. You can read more about using
sbatch in general on our Job Management page. This allows you to use additional resources that are not available on a desktop install. Note that the Matlab program and data need to be available to the
Rhino systems. This is typically accomplished by copying these files to your
When you have the data in place, start a session on a
ssh or NoMachine). Then create a batch script that will request resources on
gizmo and then run your Matlab program like the following:
#!/bin/bash # #SBATCH --qos=matlab #SBATCH --timelimit=3-0 # # These two lines need to be in your script to set up the Matlab environment . /app/lmod/lmod/init/profile module load matlab/2019a matlab -nodisplay -nosplash -nodesktop -r "run('myAnalysisJob.m $1 $2'); exit;"
The exact options above can be altered depending on your computational needs- contact Scientific Computing if you need assistance determining the needs of your script. However, the option
--qos=matlab is necessary for license management.
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.
