Network Locality

Participant : Brice Goglin.

  • Netloc Locality (hwloc ) 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.

  • hwloc targets the same challenges as hwloc but focuses on a wider spectrum by enabling cluster-wide solutions such process placement.

  • hwloc 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.
