Are you talking about logical ids (the one given by hwloc) or physical/OS

Are you talking about logical ids (the one given by hwloc) or
physical/OS ids (the one given by the OS and possibly in strange order)
? You should avoid using physical ids, but...
If logical, you can hwloc_get_obj_by_type() to get the corresponding
object, then use its ->cpuset.
If physical, you
Hi,
Im looking for a function that allows to bind the current thread to a

I found the function hwloc_set_thread_cpubind to bind a thread to a cpuset.
I also found the function hwloc_bitmap_singlify to keep only one index in
the cpuset.
But I didnt found any
