Dear all, I am running matlab on a linux server which has 64 free CPUs but when I run matlab it uses only 4 CPUs. How can I make matlab to use at leat 12 CPUs?

I am surprised you are managing to use 4 CPUs but then my only experience is with desktop PCs not servers. To use more more you will probably need the Parallel Computing Toolbox.

You need to provide more information on how you're running MATLAB on the server.
  1. Are you running through a scheduler (e.g. PBS)? If so, include a copy of the job script.
  2. Are you using cgroups?
