As for MPI, you can install different implementations.

Compiling and installing Mpich2 was very straightforward. The test again as for PVM should be spawning of /bin/hostname. The install guide is a great help in setting up MPICH2.

On the master (node0) you type:

mpd &
mpdtrace -l

And you should get back the node name (say node0) and port number (say 51227). Then you connect each node to by typing:

mpd -h node0 -p 51227

After this, you can spawn processes with mpiexec:

mpiexec -n 10 /bin/hostname.
