Re: octave in multiprocessor cpu

[Carlo Sartori]

Hi tom.
Thank for your fast answer!

I looking for a way to lot the CPU usage in all my core, now when I
start a octave program i seen in htop only one cpu running at 100% and
the other 7 are at 0%. Normally I don't use big matrices but long
cycle "for". I take a look about the libraries you have write in your
answer, but if it is only for matrices operation it isn't what I need.
I try to use google but i don't fount a simple way for make what I want.
Sorry for my bad English.
Carlo
