Re: [hwloc-users] Support for Intel's hybrid architecture - can I restrict hwloc-distrib to P cores only?

Good question. Maybe not an answer referring to hwloc. When managing a large NUMA machine, SGI UV, I ran the OS processes in a boot cpuset which was restricted to (AFAIR) the first 8 Cpus. On Intel architecures with E and P cores could we think of running OS on E cores only and having the batch

Hi Brice, I have a question about the hwloc's support for Intel's hybrid architectures, like in Alder Lake CPUs: https://en.wikipedia.org/wiki/Alder_Lake There are P (performance) and E (efficiency) cores. Is hwloc able to detect which core is which? Can I, for example, restrict hwloc-distrib to
