@vertexclique I was actually wondering whether AVX-512 is really faster than compiling the kernel with "simd" and the right rustflags , i.e. `RUSTFLAGS='-C target-cpu=native'`? I don't have a `AVX-512`-enabled cpu to try this out, but I would have the same intuition as @jhorstmann that packed simd should generate similar `AVX-512` instructions? Would be nice maybe to revisit this once to see whether we need to maintain 2 different implementations, especially when it's going to be in `std` / stable. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
