Hi all, As probably many of you know, the MPI-3 WG on tools has been (and is) working on an extension to MPI that allows tools (as well as adaptive runtime systems or applications) access to MPI internals. We have named this interface MPIT. The WG has converged on a draft for MPIT that we plan to introduce into the MPI forum process for inclusion into MPI-3. Following the new rules for MPI-3 standardization, I will be presenting this draft at the next MPI forum meeting on Tuesday afternoon. To help this discussion, the current version is attached to this email. As part of this proposal, we also propose to create an overarching chapter on tools, which includes both the existing (unmodified) PMPI interface and the new MPIT specification. This is reflected in the attached draft document. I will upload it to the Tools WG Wiki as well as the MPI SVN at the following URL (once the I can get back onto the servers, which seem to be down at the moment): https://svn.mpi-forum.org/svn/mpi-forum-docs/trunk/working-groups/mpi-3/tool... Let me know if you have any questions or comments ahead of the presentation! Thanks, Martin ________________________________________________________________________ Martin Schulz, [email protected], http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA
