I use a relatively small, and easy to use program called NetPIPE 3.6 to test 
and graph (using gnuplot) bandwidth between nodes through MPI. Douglas 
Eadline wrote a nice tutorial on how to use NetPIPE in vol. 1 no. 1 of 
ClusterWorld Magazine (December 2003). Here is the link to the NetPIPE site.


Happy Testing,
