  • highway

    Performance-portable, length-agnostic SIMD with runtime dispatch

    Also, are you familiar with https://github.com/google/highway? That gives you portable intrinsics so you can write your code only once (but still specialize per arch if it's helpful). Disclosure: I am the main author of this library.
