Not related, but didn't they used to provide a case of Leinies with each Cray system sold ? :-)

subject: RE: What is a Super Computer?

In actual fact, a supercomputer is not good at billing. The output to print is a linear process that doesn't parallelize very well. Supercomputers are good at forecasting the weather where the change in one location is based on prior conditions in neighboring locations. Easily modeled using the architecture Larry describes. The algorithm is highly mathematical and independent of external algorithms.

I have a theatre acquaintance who works for Cray here in Minneapolis. They claim they have the largest supercomputer. It's built of Intel graphic co-processors. Rumor is they burned down a rack late last year when heat dissipation methods failed. These things require their own electric sub-station, mainly to keep them cool enough to run. From a software development standpoint, the problem is how to run a debugger.
