Thanks a lot for working on this. I can't comment on the code but at
least the above core_siblings values should fix the original problem
observed with hwloc. I don't have a E5 v3 to test but installing the
hwloc package and running lstopo should confirm that it now sees a
single socket per group of 2 NUMA nodes as expected.
