ZDNET: "How to build your own supercomputer: Take a few off-the-shelf, stripped-down PCs, add some network
switches, a maze of Ethernet cabling and some homegrown Linux software, and you'll be well on your way.
Hewlett-Packard, together with a national laboratory in France, tried this recipe out. To the great surprise of many
scientists, it worked. What they ended up with is the "I-Cluster," a Mandrake Linux-powered cluster of 225 simplified
PCs from HP that has benchmarked its way into the list of the top 500 most powerful computers in the world."
