For a small two-node cluster you can get away with a 10Mbit link.
Building a Beowulf is a lot less of a pain than it at first seems... honest :-)
Just make sure you have fairly identical installations on both boxes, shove
on the beowulf extras, normally included in most distros nowadays, and add mpi
or... the other one :-) (well, it _has_ been over a year since I built mine<g>)

Simple, piece of cake (and I got away with building one for my final year

SMP aware isn't the problem, _cluster_ aware is more the thing you have to
check for (though this is a year out of date, they might be able to handle
SMP-enabled apps without too many problems now, dunno)
Try getting a simple rendering program to work first (tis one of the easier
tasks to do, IMHO) and then play to see what you can get away with :-)

Check www.beowulf-underground.org for everything Beowulf... one of the best
(again IMHO) sites going for clustering stuff. Other sites I found helpfull
not sure if the links all work, as I just copied them from my old bookmark
Have fun, and don't pull out too much hair! :-)
