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 

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):


Let me know if you have any questions or comments
ahead of the presentation!
