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
Thank you, Brice!
I'm testing it on a Lenovo P1 laptop with an i7-12800H CPU with 6P +
8E. --cpukinds option solves the problem for me:-)
hwloc-calc --cpukind 1 all
BTW, Intel's patches to improve Linux scheduling on hybrid architectures
were significantly improved this year and released

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
