Sorry,
I forgot to tell you these code block is inside a parallel OpenMP region.
This is the complete code:
#pragma omp parallel num_threads(6)
{
int tid = omp_get_thread_num();
hwloc_obj_t core = hwloc_get_obj_by_type(topology, HWLOC_OBJ_CORE, tid);
hwloc_cpuset_t set =

Hi Samuel,
yhanks for yout quick reply!
But i have a litte doubt. in a non SMT machine, Is it better use this:
hwloc_obj_t core = hwloc_get_obj_by_type(topology, HWLOC_OBJ_CORE, tid);
hwloc_cpuset_t set = hwloc_bitmap_dup(core->cpuset);
hwloc_bitmap_singlify(set);
hwloc_set_cpubind(topology,

That's because they are on different sockets. These are physical IDs
(not logical IDs), and are thus not garanteed
Dear hwloc users,
I have some questions about thread core affinity managed by hwloc.
1) A simple hwloc-hello.c program in the manual on my machine give me the
follow results:
*** Objects at level 0
Index 0: Machine#0(47GB)
*** Objects at level 1
Index 0: NUMANode#0(24GB)
