Source: https://github.com/Yoshie2000/PlentyChess

package contains BMI2, AVX2, SSE4 and SSSE3 binaries. BMI2 and AVX2 come with 2 variants (Intel and AMD) for those hungry of speed on their system. :)

enjoy!

It's terrible in SSE41 and SSE3, maybe it performs better in AVX2 and BM12, good luck!

Flavio,

i gather from previous post that your system supports up to AVX (not AVX2). in the spirit of equity, i compiled an AVX binary for you to try. see the same link. let me know if it works so i can ensure to add such kind of compile in future updates.

hope this helps. enjoy!

Good morning Chris,
I have to congratulate you and express my gratitude, after all you solved the Plenty Chess problem for me, it really works very well in AVX (not AVX2), now I just need to test it in Play Chess.

Don't forget to compile in AVX in future versions as well.
Thank you very much, have a good week!

Fantastic, the kns that were previously at a maximum of 50 are now at 1,100. It took a while, but you found the solution. Congratulations again.
Note: Don't forget future compilations in AVX.

i'm glad the AVX binary works in your system. i'll make sure to add AVX in future updates. :)
i also hope PlentyChess author (and other chess engine authors) will support AVX in their future releases. AVX systems are still fantastic these days.

You share an AVX binary, so where are your code changes needed to compile this binary? Haven't found anything in your zip.
This is not how open source software works.

SSSE3 was recompiled. please test if working on your system.
