Matlab and Matlab Runtime modules

Matlab and Matlab Runtime Environment modules are currently provided for tests.

Requirements

Using Matlab module requires to have a personal access to a Matlab License server.

An automatic access opening to Matlab license server according to your GGA is planned. But for this testing period, you have to use a workaround:

• Have an access to your Matlab license server from your laptop/workstation, usually in your laboratory network, or with a VPN access.
• Connecting to you reserved node with ssh ports redirection, as explain below.

No Matlab License server is needed to use Matlab Runtime on nodes.

Using Matlab on a node

• Connect from your workstation to your previously reserved node with a ssh port redirection.

typically, for port 27000 only:

 (workstation):~$ ssh -R 27000:<token.licenceserver.tld>:27000 <node>.<site>.g5k

For example, with a Université de Lorraine account:

 (workstation):~$ ssh -R 27000:flexlm1.univ-lorraine.fr:27000 -R 27001:flexlm1.univ-lorraine.fr:27001 <node>.<site>.g5k

• Add the dedicated path to the current lmod MODULEPATH:

 (node):~$ export MODULEPATH=/grid5000/spack/modules-others/modules:$MODULEPATH

• Set up the link to your Matlab License server through tour ssh connection, typically:

 (node):~$ export LM_LICENSE_FILE=27000@127.0.0.1

• Load the Matlab module named matlab (with version accordingly to your provided licence), for example:

 (node):~$ module load matlab/R2022a

• Start Matlab without graphical environment:

 (node):~$ matlab -nodisplay -nodesktop -nosplash

Using Matlab Runtime on a node

Matlab Runtime is used to launch an application previously compiled with Matlab.

• Connect to your reserved node
• Add the dedicated path to the current lmod MODULEPATH:

 (node):~$ export MODULEPATH=/grid5000/spack/modules-others/modules:$MODULEPATH

• Load the Matlab Runtime module named matlab-runtime (with version accordingly to Matlab used to compile the application), for example:

 (node):~$ module load matlab-runtime/R2022a

• Launch your application. Here is for example a magicsquares application (using the corresponding deployedMCRroot):

 (node):~$ ./magicsquarestandaloneApplication/run_magicsquare.sh /grid5000/spack/modules-others/matlab-runtime/R2022a 5
