Matlab GUI Example

back to the main Matlab page

GUI Session

Start a MATLAB GUI session by loading the GUI module:

module load gui

Launch Wrapper

Use the MATLAB launch wrapper to start your MATLAB GUI session:

launch_matlab_gui

If you would like to pass custom parameters to the job script, these parameters can be listed using the -h parameter:

[$USERNAME@gator3 ~]$ launch_matlab_gui -h

Usage:

        launch_xpra_gui_$application [options]
                                                                                                      
Options:                                                                                              

        -h - show this help message

        -e <executable> - program to run (REQUIRED)

        -m <memory> - memory, gb (default is 4gb)

        -p <procs> - processor cores, (default is a single core)

        -t <time> - SLURM time limit, hrs (default is 4hrs)

        -a <account> - SLURM account (default is your main account)

        -b - Use burst SLURM qos (default is main qos)

        -n - Do not wait until the job starts. I will run xpra_list_sessions later

        -j - Set up environment for a Java program

        -f <jobfile> - Job script to use for the gui session

        -l - List application presets

        -v - Verbose output to show the submission information


Defaults will be used for missing values

Advanced Launch

If you would like to access more advanced SLURM options such as dependency scheduling or incorporate MATLAB into larger launch scripts, you can use an advanced job script to start a MATLAB GUI session. Please note that this is for advanced use and does not automatically list your port connection information. This port connection info can be found by running the xpra_list_sessions command after your job has started.

Example

Note

this script is also available as '$HPC_GUI_JOB/launch_matlab.sh' after loading the gui environment module. Please feel free to change the parameters as needed for your work.
