There is a few things that can be called "clusters". What *I* call a
cluster is a thing like Beowulf systems
(http://cesdis.gsfc.nasa.gov/linux/beowulf/). Those things pool
computing power to complete large and complex calculations. Beowulf is
the name of a system based on Linux. One of the newest large Beowulf
cluster around, Avalon (http://cnls.lanl.gov/avalon/), made with 68 DEC
Alpha's, capable of 19.3 GigaFLOPS!

Another form of clustering is one of redundancy. You have for example 10
web servers serving the same URLs with load-balancing between them, for
additional client capacity and better reliability (as a few defective
nodes will only lessen performance).

Microsoft has something called Wolfpack, that I don't even know what it
does exactly.
