I talked with Martin yesterday and he would be happy to have the requirement in the standard that the Fortran wrappers MUST call the MPI C interface. This would much simplify things for the tools community. (I had earlier thought he would object to this solution.)

No! This is NOT a good idea to mandate. Open MPI currently has a bunch of Fortran functions that do NOT call the corresponding MPI_<foo> C function. Instead, they call some other back-end, internal function. I believe the NEC Fortran MPI API may do similar things. -- Jeff Squyres [email protected] For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
