What they ended up with is the 'I-Cluster,' a Mandrake Linux-powered [Mandrake, baby ;) ] cluster of 225 PCs that has benchmarked its way into the list of the top 500 most powerful computers in the world. Go over there to check out the full article. It's a good read. Should I worry that practically anyone can now build a supercomputer? Speaking of which, anyone wanna loan me $210,000?" Clusters may be old hat nowadays, but the interesting thing about this one is the degreee of customization that HP and France's National Institute for Research in Computer Science did to each machine to make this cluster -- namely, none.

Well, it seems like super clusters are becoming very easy to build hardware-wise. If you throw enough commodity at a problem, it becomes easier. I would think the biggest problem with supercomputers is no longer the hardware itself, but networking, and the programming to take advantage of the hardware. These computers still only really work for something that distributes easily. The biggest factors are now the ability to distribute, and schedule work for each node. The more nodes you engage, the more you hope your problem is CPU bound, so it will scale more.

Data transfer and message passing are such a big issue I belive the most important developments are in the networking topologies and hardware for these environments.

That said, I still want one in my basement :-)
