Minic version 3

[Werner]

Yes, normal result should be 10-10

Shall I repeat with the normal skylake compile 1-2 h ?

I think you can go with the skylake build. I removed the avx512 from the repo and try to work on it later. Won't be fixed for 3.16.

Thanks a lot

ok I had the opporunity to try AVX512 build on a Intel(R) Xeon(R) Silver 4116 CPU @ 2.10GHz compatible with AVX512 instruction set used for NNUE evaluation.

Minic-avx2 is at 530knps while Minicavx512 is around 300knps. For information, in Minic I was using pretty much the same code as the one in openblas for the dot product.

I then tried Seer-avx2 that was at 570knps while Seer-avx512 was a 390knps

It seems using avx512 is maybe decreasing the frequency of the cpu too much and lead to counter-performance in the end.

I have thus removed the avx512 instruction from the repo for the moment, and removed avx512 build of Minic3.16.
Please do not use it if you have already downloaded it.

This will be investigating later again.

Yes, this compile works much better: (40 moves in 2 min)

3.16 says "TCEC Only". Should we use 3.14?

That speed diff alone will never explain a 0:20 vs. Clover though...

@Werner are those games available somewhere for checking?

[Werner]

Yes Guenther,
I sent you an email - hope the adress is working.

I get diffent evals when using AVX2 compile. e.g. move 24 Qe3 -0.94/21 instead of + 0.35/21

actual result with avx2 Minic 3.16 x64 1CPU - Clover 2.4 x64 1CPU : 26,0/46 14-8-24 57% +49

3.16 says "TCEC Only". Should we use 3.14?

3.16 can be used. I will fix the release note.

[Guenther]

Yes Guenther,
I sent you an email - hope the adress is working.

I just downloaded the attachment of your email, thanks!
At A first quick glance it looks like the eval for Minic in those games looks quite instable?

BTW I also noticed after downloading a compilation for my hardware that it seems nnue is disabled
in the uci options by default - did you enable it in the test with Clover?
