[gmx-users] error on opening gmx_mpi

[p buscemi]

Getting closer...
( thinking a bit about the initial command structure does help....)

Now using the command:
gmx_mpi mdrun -deffnm PVP20k.nvt -nb gpu -ntomp 16 -npme 4
:-) GROMACS - gmx mdrun, 2018.4 (-:

gets past the v5 issue but a new nastygram is sent...
"The -dd or -npme option request a parallel simulation, but gmx mdrun was not
started through mpirun/mpiexec or only one rank was requested through
mpirun/mpiexec"

Inclusion of mpirun was attempted but I've not hit the proper format.
