Hi: Sure there is the howto somewhere, though not found. With Debian Linux amd64 lenny I have a working installation of openmpi-1.2.6, intel compiled, mpif90 etc in /usr/local/bin. For program OCTOPUS I need gfortran-compiled openmpi. I did so with openmpi-1.3.3, mpif90 etc (as symlink to /opt/bin/opal_wrapper) in /opt/bin.
The compilation was carried out as follows: ./configure --prefix=/opt FC=/usr/bin/gfortran F77=/usr/bin/gfortran CC=/usr/bin/gcc CXX=/usr/bin/g++ --with-libnuma=/usr/lib As I am the only user, I use to place everything in my .bashrc. Specifically, #For openmpi-1.2.6 Intel compiler if [ "$LD_LIBRARY_PATH" ] ; then export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib" else export LD_LIBRARY_PATH="/usr/local/lib" fi #For openmpi-1.3.3 gnu (gfortran) compiled if [ "$LD_LIBRARY_PATH" ] ; then export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/lib" else export LD_LIBRARY_PATH="/opt/lib" fi Command $ompi_info always reports about the intel compiled. How can I have info about the gfortran compiled (and runtime) ?
