[gmx-users] Running QM/MM in parallel (ORCA/GMX)

Hey there,

after working through the helpful tutorials about QM/MM I now ran into a problem when it comes to run ORCA/GROMACS in parallel and I could not find anything about this in the mailing list or on the gromacs page. I can run GROMACS or ORCA in parallel and QM/MM on a single core, but not in parallel using OpenMPI. My machine complains about openmpi as soon as I try to run QM/MM, but it doesn't complain when running a MD simulation in parallel.

As a first step, could someone provide an example of how to do a parallel QM/MM run or share some experience?
