Running MATLAB Software Interactively
Learn how to run MATLAB software interactively on NREL HPC systems.
To run MATLAB interactively 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 NREL HPC systems, see System
Running MATLAB via an Interactive Job
After connecting to the login node, the next step is to start an interactive job. For example, the following command gets a user-selected number of nodes for interactive use, taking as input tasks per node, job duration, and account.
$ salloc --nodes=<number of nodes> --ntasks-per-node=<tasks per node> --account=<your account here> --time=<desired time>
When your job starts, you will have a shell on a compute node.
- To submit an interactive job you must include the
and include a valid project allocation handle. For more information, see
- For more information on interactive jobs, see Running Interactive
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
and starting a simple MATLAB terminal (no GUI),
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
and start the MATLAB GUI,
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.
