Hi Matt,
the easiest way is to set openmpi as default for the whole system.
With
update-alternatives --get-selections |grep mpi
I have this:
mdrun_mpi auto /usr/bin/mdrun_mpi.openmpi
mpi auto /usr/lib/openmpi/include
mpirun auto /usr/bin/mpirun.openmpi
You can copy&paste this output to a file selections.list and then run:
cat selections.list | sudo update-alternatives --set-selections
regards,
Nuno
