The only MPI's I could find are: $ whereis mpirun mpirun: /usr/bin/mpirun.openmpi /usr/bin/mpirun /usr/bin/X11/mpirun.openmpi /usr/bin/X11/mpirun /usr/share/man/man1/mpirun.1.gz
$ whereis mpicxx mpicxx: /usr/bin/mpicxx /usr/bin/mpicxx.openmpi /usr/bin/X11/mpicxx /usr/bin/X11/mpicxx.openmpi /usr/share/man/man1/mpicxx.1.gz $ whereis mpicc mpicc: /usr/bin/mpicc /usr/bin/mpicc.openmpi /usr/bin/X11/mpicc /usr/bin/X11/mpicc.openmpi /usr/share/man/man1/mpicc.1.gz Not sure if this counts as multiple MPIs...'which mpicxx' turned up nothing until I did 'sudo apt-get install libopenmpi-dev', and I have installed nothing else since... -Harriet On Thu, Apr 7, 2016 at 5:57 PM, Cody Permann <codyperm...@gmail.com> wrote: > This generally means your compile environment and runtime environment > aren't the same.
