How do I force matlab to run on a certain processor other than the first one?

Aloha Folks, sometimes I have Matlab running doing some crunch work and its taking over resources from other programs, making it sometimes hard to do any sort of work.

I am wondering if there is a way to assign a worker other than the primary to be used for matlab. This is not a parallel question, though I am aware that I may need parallel/distributive toolboxes. Perhaps I would also need to put a lit on memory usage? I am using Linux, so perhaps a combination with PBS or similar might be an option?

I am very thankful for anyone who could help me with this,

Thank you!
