  Performance-portable, length-agnostic SIMD with runtime dispatch

  

As to compilers, the -mprefer-vector-width flag indeed prevents AVX-512 from being generated by default. This is because autovectorization often results in only sporadic use of SIMD instructions, which can be counterproductive. I believe intrinsics (or preferably a library built on top such as our github.com/google/highway) are the most reliable and effective way to use SIMD.
