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.
