Hi,
Thanks. The 2.1.1, which was presented last time, in my opinion does not
seem to solve the right problem. Instead of defining a way for
unambiguous addressing of the threads in MPI, which would eliminate the
MPI_Probe/Recv ambiguity and many other issues, it attempts to add yet
another concept (this time, a message id) in the current situation where
any thread can do what they please.
Best regards.
Alexander

Subject: [Mpi-22] Higher-level languages proposal
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.
