This question already has an answer here:

I'm running a programme, and below are some graphics from the resources monitor from windows 8, while running my programme in version 9 of mathematica. Sorry for the foreign writings in the pics, but my windows is in Portuguese.

enter image description here enter image description here enter image description here

My question is why the low CPU usage by mathematica? Is there a way to change that limit, and should I change it?

Any help would be appreciated.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ How many kernels are your licensed for? Is your code explicitly requesting parallel sub-kernels? Im not massively familiar with the Linux task manager program but it looks to me as if your 32% CPU usage is coming from just 1 or 2 of the cores running at full capacity. Try explicity starting some parallel kernels. $\endgroup$ – Gordon Coale Feb 27 '15 at 9:14
