David, thanks for answering.
strange. i've installed one version of gromacs on the front end machinne but when it tries to run mprun_mpi it says that cannot find it (obvously because is searching on a node that is not the frontend machinne).
Where can i find a step by step example of working with gromacs-mpi???
I'm the administrator of the cluster and know nothing about molecules :(
Thanks
Francisco

That's probably the most common combination.
You just need one version of gromacs
./configure --enable-mpi
