My system has 48 CPU cores. Is StarTools able to use all of them?

StarTools uses all your CPU's cores to speed up processing in situations where it makes sense. As of 1.7, however, StarTools will offload suitable, heavy arithmetic to your GPU as well.

Please note that using multiple cores for tasks that are memory bus constrained, can actually have an adverse effect on performance, so you may find that not all algorithms and modules use all cores all of the time.
