Parallel computations on UQLab?

I looked up similar Q&A regarding parallelization of UQLab and found out that UQLab does not support such a thing. However, all 8 of my pc’s cores are utilized when running a simple script that calculates PCE coefficients. The model used is also not parallelized. Could it be a MATLAB thing that has nothing to do with UQLab?

Dear ChrisP,

Matlab’s linear algebra functions are multithreaded. See:

If that causes you problems you can change it:


Best regards,

Thank you very much, the maxNumCompThreads utility is exactly what i was looking for
