Creating Raspberry Pi clusters is a popular hacker activity. Bitscope has been commercializing these clusters for a bit now and last year they created a cluster of 750 Pis for Los Alamos National Labs. You might wonder what an institution know for supercomputers wants with a cluster of Raspberry Pis. Turns out it is tough to justify taking a real high-speed cluster down just to test software. Now developers can run small test programs with a large number of CPU cores without requiring time on the big iron.

[...] The system is modular with each module holding 144 active nodes, 6 spares, and a single cluster manager. This all fits in a 6U rack enclosure. Bitscope points out that you could field 1,000 nodes in 42U and the power draw — including network fabric and cooling — would be about 6 kilowatts. That sounds like a lot, but for a 1,000 node device, that's pretty economical. The cost isn't bad, either, running about $150,000 for 1,000 nodes. Sure, that's a lot too but not compared to the alternatives.

Huh. That's actually not a bad idea for sounding so silly at face value.
