Hi, HWLOC 2.0.x support was brought up during the call. FYI, I am currently using (and still testing) hwloc 2.0.1 as an external library with master and I did not face any major problem; I only had to fix minor things, mainly for putting the HWLOC topology in a shared memory segment. Let me know if you want me to help with the effort of supporting HWLOC 2.0.x.
