Hi, it looks like you installed Open MPI 2.0.1 at the same location than previous Open MPI 1.10, but you did not uninstall v1.10. the faulty modules have very been likely removed from 2.0.1, hence the error. you can simply remove the openmpi plugins directory and reinstall openmpi
rm -rf /usr/local/lib/openmpi make install Cheers, Gilles On Fri, Jan 6, 2017 at 6:30 PM, Solal Amouyal <solal.amou...@gmail.com> wrote: > FYI: It's my first time posting here and I'm quit a beginner in MPI. > > I recently updated my gfortran (from 4.7 to 6.1.0) and OpenMPI (from 1.10 to > 2.0.1) compilers.
