API is still a bit unstable and may change. - Add a primitive "first use" component that simply has each process "touch" the pages that they want to use, thereby [hopefully] locking them locally to a specific processor - Add hooks in ompi_mpi_init to enable memory affinity when processor affinity is used. - Added hooks in ompi_mpi_finalize to shut down memory affinity when it was initialized during ompi_mpi_init. - Added right hooks in ompi_info to display maffinity components. This commit was SVN r7044.
