On Linux MATLAB R2019b spawns around 150 threads on starting. On our shared servers we limit the number of processess a user can run and thus matlab is crashing. Is there any way to limit the number of threads that MATLAB will spawn?

在 MATLAB Online 中打开

By default, MATLAB uses the multithreading capabilities of the computer on which it is running.

You can specify the startup option "-singleCompThread" to Limit MATLAB to a single computational thread. This can be done by starting MATLAB program from Linux system prompt using

matlab -singleCompThread

Check matlab (linux) for more startup options.

Alternatively, assign start-up options in the MATLAB .matlab7rc.sh Start-up File. Modifying the ".matlab7rc.sh" file defines start-up options every time you start MATLAB.
