Termination while running a MPI

Termination while running a MPI

I am trying to run a mpi code on the intel compiler. The code works fine for one processor but when np>1 then I get the following error

p4_error: Child process exited while making connection to remote process on n01. I can rsh into n01 without a password. What might the problem be?

Thanks in advance.
