Google on the web for mpi example programs.  There are usually some in
an "examples" directory in most mpi installations as well.

There are occasional columns on MPI (with example programs) by e.g.
Forrest Hoffman in Linux Magazine; some of these make their way into
their online archives (I've found them there in the past).  Ditto Jeff
Squyres with his excellent "MPI Mechanic" column in Cluster World
Magazine, although I think CWM still lacks a web archive of old
articles.  Still, Jeff could probably send you some example code from
old articles along with the column text if you asked nicely.  Naturally,
you should probably go ahead and subscribe to either or both of these
mags to get a more regular dose of education and advice and source
code...;-)
