If no output is produced, then there are plenty of potential problems - faulty
Gromacs installation, buggy MPI implementation (they are out there!), node
problems, etc. Whoever is in charge of the cluster (your system administrator)
may be able to probe system log files or run debug analysis to see what's wrong.
There's nothing more anyone here can likely provide.
