Hi, May be we add a couple of calls to pass data back and forth between the client and MPI? Either assertions proposed by Dick Treumann, or more extensible (MPI_Info based?) approach proposed by Jeff Squyres? That's admittedly connected to subsets, but this is only an addition, no backward incompatible change. MPI 2.2? Best regards.

Please send any items you may have for 2.2 to mpi-22_at_[hidden] and/or upload them to the wiki (and let us know). I had made a note of the following items from the last meeting that were deferred to 2.2: * support for long long in maxloc, minloc * fix meaning of first two sentences in intercommunicator barrier * Ex 5.8 uses old style MPI_UB * Many functions say "integer" instead of "nonnegative integer" * const in C++ bindings * IN, OUT, and INOUT handle types broken * MPI_CHAR, MPI::CHAR should be signed char or char? * Need 64-bit sizes for count in messages * Sizes of MPI_Aint and MPI_Offset should not be different * New predefined types MPI_AINT and MPI_OFFSET * New predefined types corresponding to new types in C99, Fortran 2003, and C++ some year _______________________________________________ mpi-22 mailing list mpi-22_at_[hidden] http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi-22 --------------------------------------------------------------------- Intel GmbH Dornacher Strasse 1 85622 Feldkirchen/Muenchen Germany Sitz der Gesellschaft: Feldkirchen bei Muenchen Geschaeftsfuehrer: Douglas Lusk, Peter Gleissner, Hannes Schwaderer Registergericht: Muenchen HRB 47456 Ust.-IdNr.
