This man speaks wisely.

You waste valuable processor time passing data over the LAN if you build a
Beowulf.  The original Beowulf of 16 486DX4-100's built by NASA required two
10mbps networks to carry the data traffic.  If you build a cluster of
workstations, however, you can cut the network traffic down to a complete
minimum through clever programming.  My ray-tracing cluster uses the network
only when it begins a frame, and when each workstation finishes it's section
of the frame.  The network is completely unused while each workstation is
working flat out.

Agreed.  Excellent learning experience, though.
