I am seeing the following errors when using NAG Fortran (v5 or v6): Error: /sandbox/hargrove/OMPI/openmpi-2.0.0rc3-linux-x86_64-nagfor-5/openmpi-2.0.0rc3/ompi/mpi/fortran/use-mpi-tkr/mpi_comm_spawn_multiple_f90.f90: Argument 3 to MPI_COMM_SPAWN_MULTIPLE has data type DOUBLE PRECISION in reference from MPI_COMM_SPAWN_MULTIPLEN and CHARACTER in reference from MPI_COMM_SPAWN_MULTIPLEA Error: /sandbox/hargrove/OMPI/openmpi-2.0.0rc3-linux-x86_64-nagfor-5/openmpi-2.0.0rc3/ompi/mpi/fortran/use-mpi-tkr/mpi_testall_f90.f90: Argument 4 to MPI_TESTALL has data type DOUBLE PRECISION in reference from MPI_TESTALLI and INTEGER in reference from MPI_TESTALLS
I am 99% certain this means the FC=-mismatch fix is missing. To be precise, v2.x is missing https://github.com/open-mpi/ompi/commit/1ce5393f -Paul -- Paul H.
