[Beowulf] Adding Latency to a Cluster Environment

given the difficulty of accurately adding a small amount of latency
to a message passing interface, how about this: hack the driver to 
artificially pre/append a constant number of bytes to each message.  
they will appear to take longer to process, giving high-resolution added
delays.  course, this will also saturate earlier, but that's only the upper
knee of the curve: you can still learn what you want...

regards, mark hahn.
