Can you improve CPU performance with Intel library?

I mean this https://software.intel.com/en-us/mkl ? I am VERY suspicious.

It depends on what calculations you are doing.

If you want to speed up big matrix multiplications, FFTs or other numerical code (and you don't want to push it to the GPU), MKL can help you. But an alpha-beta chess engine does none of that. NN engines do big matrix multiplications and convoltions, but a GPU is typically a better bet for that anyway.

It's a bit like asking whether having an lawn mower is useful. It depends; if you want to cut the grass, it's great, but if what you needed was a place to cook dinner, perhaps not so much…

Maybe VSL can help if you need a lot of random number ... but fft, blas and lapack won't be use for a a/b search (except for texel tuning).

Maybe I can speedup Lc0 from 10 nps to 15 nps . Not worth the effort as there were warnings about overheating and big RAM usage.
