comment in ompi_comm_invalid() in source:/trunk/ompi/communicator/communicator.h. Short version: - ompi_comm_invalid() returns TRUE for MPI_COMM_NULL - therefore MPI_COMM_C2F needs to explicitly check for MPI_COMM_NULL (because it uses ompi_comm_invalid()) - make ~20 MPI functions only call ompi_comm_invalid() instead of calling ompi_comm_invalid() *and* checking for MPI_COMM_NULL (~40 MPI functions already only called ompi_comm_invalid() -- we should be consistent) - similar issue for ompi_win_invalid(), so I added a cross-referencing comment in win.h and fixed MPI_WIN_SET_NAME to only call ompi_win_invalid() (and not check for MPI_WIN_NULL) This commit was SVN r9970.
