The windows VNNI binary does not work. about stockfish HOT 10 CLOSED

I don't see any mention of VNNI support for that processor.

Not sure if below page is correct that mentioned Raptor lake support it.

Actually , from the page , it seems support the VNNI:

from stockfish.

Then you might have a genuine issue. You have AVX-VNNI support according to what I read quickly, but I don't believe you have full AVX-512 support. It might be the case that Stockfish assumes that VNNI is a superset of AVX-512.

If you are someone who knows how to run Linux virtual machines quickly, you can cat /proc/cpuinfo and probably put this issue to rest quite quickly.

The binary tested is vnni512 it requires support for : CXXFLAGS += -mavx512f -mavx512bw -mavx512vnni -mavx512dq -mavx512vl -mprefer-vector-width=512 it could be the op needs to pick avxvnni CXXFLAGS += -mavxvnni

anyway, I see we don't build that as part of the assets provided in the release, so that might have to be added for the future. Providing binaries for every variation of processors is a bit tedious there are many flavors (a 2019 image https://twitter.com/InstLatX64/status/1114141314441011200 )

Thanks, that make sense 13600KF does not support full avx512-vnni.
Currently the best usable one for my cpu is bmi2.

I think we might need to put out some more information regarding these binaries, there was a similar confusion here #5110

from stockfish.

In principle running the scripts/get_native_properties.sh we can get which binary should be used. Pasquale had a version that also worked on windows for the downloader.

I'll close this since it is directly to the users cpu and not to binary (stockfish) itself.
We might need to help the user more in the future to select the right binary.
