Subject: [OMPI users] How is hwloc used by OpenMPI
From: Blosch, Edwin L (edwin.l.blosch_at_[hidden])

I see hwloc is a subproject hosted under OpenMPI but, in reading the documentation, I was unable to figure out if hwloc is a module within OpenMPI, or if some of the code base is borrowed into OpenMPI, or something else. Is hwloc used by OpenMPI internally? Is it a layer above libnuma? Or is it just a project that is useful to OpenMPI in support of targeting various new platforms?
