[Beowulf] Good demo applications for small, slow cluster

[Ellis H. Wilson III]

Jim,

Not sure if this "demo application" reaches beyond your intent, or if it 
really falls into the demo category, but Graph500 has a solid benchmark 
(by the same name) for graph-related problems, and there is an MPI 
version of it available in the source.  You can scale the size of the 
problem with parameters to meet your time and resource constraints. 
Fairly well documented, and well used so I think it should work on most 
platforms.

Best,

ellis
