This document does *not* fix the scalability and other well-known issues with MPIR -- it just consolidates and standardizes the slightly-different versions of MPIR that were floating around out there.
However, based on what we have in the trunk today, Open MPI doesn't follow that document. As Ralph pinpointed it, the current version work with several tools (tv, stat, padb) as is, so that means the tools do not really follow that document either. What a mess
All the time we spent in the MPI Forum talking about the MPIR interface, and look at the result !
