mdrun doesn't take '-N 2' but I'm not sure this is the problem. Otherwise, looks fine to me. > I got an error message "Segmentation fault" from my script output, but > no error message in both log files.

Your MPI setup might require you use a command like "mpirun -N 2 mdrun_mpi ..." to make it work - the segfault might be a gromacs-MPI interaction problem. If you can run an MPI process from the command line you may get more helpful feedback.
