it would seem a good idea to completely scrap the current implementation. It was written in 2012 and a lot of fancy shmancy stuff has been added to the supported mpi flavors since then.

Currently brainstorming if it is a good idea to have a general set_pinning() method in mpi.py that throws a NotImplmentedException. Every MPI flavors should extend this function with their correct cpu pinning options.
