Thanks for the replies, folks! Checking I've understood the respective updates correctly: - x86_64 implies SSE2 capability - most i686 machines still in use are also SSE2 capable - Accelerate provides native BLAS/LAPACK APIs for Mac OS X - (ATLAS SSE2 or OpenBLAS) + manylinux should handle Linux - (ATLAS SSE2 or OpenBLAS) + mingwpy.github.io should handle Windows - Numba can optimise at runtime to use newer instructions when available The choice between an SSE2 build of ATLAS and OpenBLAS as the default BLAS/LAPACK implementation doesn't appear to have been made yet, but also shouldn't significantly impact the user experience of the resulting wheels. Does that sound right?
