Hi Ashraf,

Are you using MPICH-2?
If you are going to use Intel MPI Library you need to set environment variable variables first.
Run:
'. /full/path/to/intel/mpi/installation/bin64/mpivars.sh'

Kill all existing mpd.py processes left from previous run.
And try one more time to run mpirun.

PS: you need to have passwordless access to all nodes.

Regards!
Dmitry
