[mpich-discuss] Problem Running MPI on cluster

[Kenneth Raffenetti]

Does your mpi_hello_world binary exist in the same directory on all the 
machines you are trying to run on? Can you try running this:

/usr/lib64/mpich/bin/mpirun -n 4 -f host_file hostname

If it outputs the names of the hosts in your hostfile, we can be 
confident that your mpirun and ssh setup is functioning correctly.
