Many thanks for the input. When I look for mpirun:
brant.abbott@rust:~$ 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 If I use mpirun.openmpi everything works as normal. I suppose mpirun is executing the MPICH version. I'm not entirely sure why when logged in a root it behaves differently, but good enough for me to just use the alternative command.
