Doug Gregor did 98% of the work on this proposal, but it will likely be Torsten or I presenting this proposal next week in Chicago (5-7pm Monday). The short version of the attached text is that we propose the following: - add some extensions to MPI to allow higher-level languages to build their own MPI bindings - if all that works out nicely, deprecate and eventually remove the official MPI C++ bindings Don't let the proposal name fool you -- the features that we're proposing are inspired by letting higher-level language build their own bindings, but some of the issues (e.g., new MPI_BLOB datatype) are fairly wide-reaching. We haven't yet put a "2.2" or "3.0" label on this proposal (which is why I have not entered it in the MPI-2.2 ticket system); I can see valid arguments for both sides. More feedback is required from the Forum first. -- Jeff Squyres Cisco Systems *
