According to the MPICH Changes web page, "Fortran 2008 bindings are enabled by default and fully supported” starting in MPICH 3.2. Could someone please point me to documentation on using the bindings? My installation of MPICH 3.2 doesn’t find the mpi_f08 module described in MPI 3.1 standard. My draft copy of the standard states the following at the beginning of Section 17.1.2: "An MPI implementation providing a Fortran interface must provide a module named mpi_f08 that can be used in a Fortran program.” Below is an example of what I’m seeing. Damian $ cat use_mpi_f08.f90 program main use mpi_f08 implicit none end program $ mpifort use_mpi_f08.f90 use_mpi_f08.f90:2:6: use mpi_f08 1 Fatal Error: Can't open module file ‘mpi_f08.mod’ for reading at (1): No such file or directory compilation terminated. $ mpiexec --version HYDRA build details: Version: 3.2 Release Date: Wed Nov 11 22:06:48 CST 2015 CC: gcc CXX: g++ F77: gfortran F90: gfortran Configure options: '--disable-option-checking' '--prefix=/opt/mpich/3.2/gnu/7.2.0' 'CC=gcc' 'CXX=g++' 'FC=gfortran' '--cache-file=/dev/null' '--srcdir=/home/rouson/Desktop/Builds/opencoarrays/prerequisites/downloads/mpich-3.2/src/pm/hydra' 'CFLAGS= -O2' 'LDFLAGS=' 'LIBS=-lpthread ' 'CPPFLAGS= -I/home/rouson/Desktop/Builds/opencoarrays/prerequisites/builds/mpich-3.2/src/mpl/include -I/home/rouson/Desktop/Builds/opencoarrays/prerequisites/downloads/mpich-3.2/src/mpl/include -I/home/rouson/Desktop/Builds/opencoarrays/prerequisites/downloads/mpich-3.2/src/openpa/src -I/home/rouson/Desktop/Builds/opencoarrays/prerequisites/builds/mpich-3.2/src/openpa/src -D_REENTRANT -I/home/rouson/Desktop/Builds/opencoarrays/prerequisites/builds/mpich-3.2/src/mpi/romio/include' Process Manager: pmi Launchers available: ssh rsh fork slurm ll lsf sge manual persist Topology libraries available: hwloc Resource management kernels available: user slurm ll lsf sge pbs cobalt Checkpointing libraries available: blcr Demux engines available: poll select _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
