AVX 512 will be the future
Are there any libraries that allow me to write different versions of the same function (AVX-512, AVX2, SSE, etc) and then automatically choose the best one that the system supports at runtime? Or maybe even better, the compiler generates multiple versions for me.<p>In other words, one binary that takes advantage of new instructions but still runs on older hardware. It doesn't really have to be older either, plenty of brand new CPUs doesn't support AVX-512.
