Running MATLAB Software Interactively on the Eagle System

Learn how to run MATLAB software interactively on the Eagle system.

To run MATLAB on Eagle there are two ways to proceed: you can choose to start an interactive job and use a basic MATLAB terminal (no GUI), or you can use the GUI with a FastX session on a DAV node. For information on how to connect to Eagle, see System Connection. 

Running MATLAB via an Interactive Job

After connecting to Eagle, the next step is to start an interactive job. For example, the following command gets # nodes for interactive use for an hour:

$ srun -N # --time 01:00:00 --account=<handle> --pty $SHELL

When your job starts, you will have a shell on a compute node.

Notes:

  • To submit an interactive job you must include the --account=<handle>flag and include a valid project allocation handle. For more information, see User Accounts.
  • For more information on interactive jobs, see Running Interactive Jobs.

From the shell on the compute node, the next steps are to load the MATLAB module to set up your user environment, which includes setting the location of the license server,

$ module load matlab

and starting a simple MATLAB terminal (no GUI),

$ matlab -nodisplay

Running MATLAB via a FastX Session on a DAV Node

For instructions on starting a FastX session on a DAV node, see the FastX page. Once you have started a FastX session and have access to a terminal, load the MATLAB module to set up your user environment, which includes setting the location of the license server,

$ module load matlab

and start the MATLAB GUI,

$ matlab &

With FastX, this will enable you to use the GUI as if MATLAB was running directly on your laptop. The ampersand "&" lets MATLAB run as a background job so the terminal is freed up for other uses.
