Phoronix: Clear Linux Discovers Another AVX2/AVX512 Fix/Optimization To Yield Better Performance

For those running a system with AVX-512 support, Clear Linux builds as of this week should be yielding even better performance on top of their existing AVX2 and AVX-512 optimizations...

Is there a git repo of Clear Linux’ glibc somewhere?

It is here.

Well, I'm certain some people have been suggesting this already.
But why don't mainstream distros adopt per CPU versioning for their package managers, so certain packages can get similar improvements like Clear gets, even if that is on some specific packages?
You wouldn't even have to replace everything. AFAIK, things like the glibc could be compiled with such patches and -march switches and still be ABI compatible.

Mostly due to the increased QA/testing/maintenance burden.

Besides glibc is already pretty well optimized for various architectures with runtime switches. It is everything else that is problematic.

Because targeted binaries are a better solution and you'd still need at least two sets of stable repos with -march=icelake-client -mtune=westmere & -march=nzver2 -mtune=bdver2
