Thanks Marcin, that's interesting! Actually I have the same CPU in a
laptop, so I could cross-check how the Windows package influences the
whole thing. (I'm assuming you were on Linux with that test?)
So as I suspected, it's not so easy in general. BTW, if you're really on
Linux, do you know what your openblas version is?
thanks
