Yeah thts the fun of it, you create your kernel/function so that the simd level is a template parameter, and then you can use simple branching like:
if(supports<avx512>){
myAlgo<avx512>();
}
else{
myAlgo<avx>();
}
Ive also used it for benchmarking to see if my code scales to different simd widths well and its a huge help
- dyaroshev 2y agoFYI: You don't want to do this. `supports<avx512>` is an expensive check. You really want to put this check in a static.
- spacechild1 2y agoI guess this was just pseudo-code. Of course you don't want to do a runtime feature check over and over again.
