Interesting, it looks like "GOMP_CPU_AFFINITY" is from OpenMP: https://spec.org/cpu2017/flags/aocc4...022-12-08.html

It is from OpenMP - mainly because OpenMP is one of the frameworks that provides the means to adequately describe say, a 256 core CPU's cache, interconnect and memory layout. It's really not trivial to get maximum performance out of these things!

No it's a terrible idea. This requires the application to actually be aware of this shit and write to it. Unreal. It's not gonna happen.

Indeed. Just checked the mailing list and was surprised it hasn't been shot down yet.
