Personally, though, I fear you are right with your assumption, but I am happy to be proven wrong.

Per MPI-3.1 p613 table 17.1, this means ***changing all the back-end symbols*** that are used for PMPI-style interception. A concrete example: - in mpif.h / the mpi module, MPI_SEND will become MPI_SEND_FTS - in the mpi_f08 module, MPI_SEND will become MPI_SEND_F08TS I.e., anywhere the application calls MPI_SEND, it will be transmogrified to either MPI_SEND_FTS or MPI_SEND_F08TS. And the choice buffer passed will be a descriptor (which may therefore be a subarray, not a contiguous buffer), not a naked pointer. Here's my questions: 1. Do any tools support Fortran descriptors as choice buffers? 2. Do any tools intercept the symbols as described in MPI-3.1 table 17.1? -- Jeff Squyres [email protected]<mailto:[email protected]> _______________________________________________ mpiwg-tools mailing list [email protected]<mailto:[email protected]> https://lists.mpi-forum.org/mailman/listinfo/mpiwg-tools -- Jeff Squyres [email protected]<mailto:[email protected]> _______________________________________________ mpiwg-tools mailing list [email protected]<mailto:[email protected]> https://lists.mpi-forum.org/mailman/listinfo/mpiwg-tools -- Jeff Squyres [email protected]<mailto:[email protected]>
