Re: Perft function too slow because of vcruntime140.dll

clang has never been fast for Sapeli on my Linux boxes. On my ryzen 1700x, running fedora 31, Sapeli 1.76 is faster when compiled with clang. With gcc 9.2.1 and build-profile from your Makefile: $ make build-profile gcc -Wall -pedantic -Wextra -Wshadow -Ofast -march=native -DNDEBUG -fprofile-genera...

Re: Perft function too slow because of vcruntime140.dll

clang has never been fast for Sapeli on my Linux boxes. Something is slowing down "clang -> LLVM -> asm -> elf" at least for Sapeli. gcc has 7x faster perft compared to clang. clang + Ofast + strip ./sapeli -bench ... = nodes 26975836 mnps 0.899 time 30.001 ./sapeli -perft 6 = nodes 124132537 mnps 2...

Re: What is the strongest python engine?

Stockfish in every language basically ? https://github.com/Dani4kor/stockfishpy That's a wrapper, not an engine. I don't think you can count it in the running for "strongest python engine". That's true, it's a wrapper. :oops: There doesn't seems to be a Stockfish python port as I wrongly assumed. N...
