Neither #12 nor #21 talks about adminstrative restriction... So we'd need this ? 1) hwloc_topology_from_cpu/membind(pid) (or cpuset as argument) => restrict topology to given cpu/membind 2) hwloc_topology_get_from_pid(pid) reads both cpu/membind and administrative restrictions from another process instead of current process Brice
