Participant : Brice Goglin.

Netloc Locality (NetLoc ) is a library that extends hwloc to network topology information by assembling hwloc knowledge of server internals within graphs of inter-node fabrics such as Ethernet or Infiniband.
-
NetLoc targets the same challenges as hwloc but focuses on a wider spectrum by enabling cluster-wide solutions such process placement [21] .
-
NetLoc is developed in collaboration with University of Wisconsin in LaCrosse and Cisco, within the Open MPI project.

NetLoc is composed of 15 000 lines of C. It was recently merged in the hwloc repository was better integration.
