Limited number of matlab stat toolbox licences?

HPC Technical

Many of my batches crashed yesterday with the following message:

License checkout failed.
License Manager Error -4
Maximum number of users for Statistics_Toolbox reached.
Try again later.

Troubleshoot this issue by visiting:
https://www.mathworks.com/support/lme/R2022a/4

Diagnostic Information:
Feature: Statistics_Toolbox
License path:

/home/users/c/clairis/.matlab/R2022a_licenses:/opt/ebsofts/MATLAB/2022a/licenses/license.dat:/opt/ebsofts/MATLAB/2022a/licenses/network.lic
Licensing error: -4,132."

I guess this comes from the fact that matlab/unige only provides with a limited number of pcs which an use the toolbox in parallel, but I was wondering if there isn’t a way to bypass that issue as this clearly limits the interest of using the cluster?

Dear Nicolas,

Regarding Matlab this is needed to reserve licence in the sbatch command. All is documented here :

But if you need to launch multiple instance of you script you mush compile matlab

After that you are not limited with the number of licence.

Best regards,
