Summary

Load and run

  • You can use the module system to load a specific version of Matlab

    module load matlab

  • You can start the Matlab GUI

    matlab &

    • or On-demand on LUNARC

  • You can run Matlab on the terminal

    matlab -nodisplay [-singleCompThread -nosplash -nodesktop]

Slurm job scheduler and Matlab in terminal

  • You can configure the cluster

    configCluster.sh <project-id if on UPPMAX or LUNARC>

  • You can can add job settings needed to run jobs from Matlab

    c.AdditionalProperties.<properties like AccountName/WallTime>

  • You can work in the Matlab terminal interface

    • It works almost the same as with GUI.

  • You can submit jobs from inside the Matlab terminal interface

    job = batch('myScript');

  • You can write and submit a Matlab batch script

    • Create a batchscript.sh

    !/bin/bash
#SBATCH -A my_account
#SBATCH -t 00:10:00
module load <matlab version>
matlab -nojvm -nodisplay -r "monte_carlo_pi(100000)"

    sbatch batchscript.sh``

  • You can use GPUs with Matlab

    c.AdditionalProperties.GpusPerNode = 1;

Matlab GUI and Slurm

  • You can submit jobs from inside the Matlab GUI

    c=parcluster('name-of-your-cluster');
%extra slurm settings
j = c.batch(@myfunction,'nr. outputs',{'list of input args'},'pool','nr. workers');
j.wait;                               % wait for the results
j.fetchOutputs{:};                % fetch the results

    • Note that batch also accepts script names in place of function names, but these must be given in single quotes, with no @ or .m.

  • You can work with Matlab in parallel

    parfor
spmd
parfeval

  • You can check that you are in an interactive session

    • After running interactive.. on UPPMAX or LUNARC you will see that the linux prompt shows another hostname

Add-Ons

  • You can view add-ons and toolboxes

    • It is all more or less graphical

  • You can install add-ons

    • Search in add-ons explorer and install.

    • Ends up in local folder and is in the path so it should be reached wherever you are in the file tree.

Session-UPPMAX: Matlab client on the desktop

  • You can use the Matlab client on the desktop

    • download and decompress UPPMAX configure file.

    • run configCluster on local MATLAB and set user name

    • Steps to run

      • set parcluster settings, like you do otherwise.

Session: Matlab in Jupyter

  • You can start run Matlab in Jupyter

    • You need to configure and install some python packages the first time

    • After that starting jupyter will find the Matlab kernel
