-For users from MPG we offer the flat rate [[https://www.soli.mpdl.mpg.de/en/software/matlab/|License from MPG ]], which covers all toolboxes including MATLAB Parallel Server (formerly Distributed computing). However, you need to apply for the access to the license.

Make sure to familiarize yourself with the ''srun'' command and its parameters and set a higher time limit by specifying the switch ''-t'', see [[en:services:application_services:high_performance_computing:running_jobs_slurm|here]].
