No, prime is best used with nothing else interrupting it, not even switches to other instances of itself. One mprime per CPU. It is a very tightly written assembly program which "cooks" the CPU pretty nicely in torture mode (start with -t). Remember this is hardware test only, it does nothing about OS hickups.
