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.

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.

  • $\begingroup$ 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
