Hi,
I want to avoid separate MPI distributions since we compile many
MPI software packages. Having more than one MPI distribution
(at least) doubles the amount of work.
For now I came up with the following solution:
1. compile openmpi using gfortran as the Fortran compiler
and install it in /usr/local/openmpi
2. move the Fortran module to the directory
/usr/local/openmpi/include/gfortran. In that directory
create softlinks to the files in /usr/local/openmpi/include.
3. compile openmpi using ifort and install the Fortran module in
/usr/local/openmpi/include.
4. in /usr/local/openmpi/bin create softlinks mpif90.ifort
and mpif90.gfortran pointing to opal_wrapper. Remove the
mpif90 softlink.
5. Move /usr/local/openmpi/share/openmpi/mpif90-wrapper-data.txt
to /usr/local/openmpi/share/openmpi/mpif90.ifort-wrapper-data.txt.
Copy the file to
/usr/local/openmpi/share/openmpi/mpif90.gfortran-wrapper-data.txt
and change the line includedir=${includedir} to
includedir=${includedir}/gfortran
6. Create a wrapper script /usr/local/openmpi/bin/mpif90:
#!/bin/bash
OMPI_WRAPPER_FC=`basename $OMPI_FC 2> /dev/null`
if [ "$OMPI_WRAPPER_FC" = 'gfortran' ]; then
exec $0.gfortran "$@"
else
exec $0.ifort "$@"
fi
The reason we use gfortran in step 1 is that otherwise you get those
irritating error messages from the Intel libraries, cf.
