The bulk of the 86 eight-way machines will be installed at the Fritz Haber institute, which is doing research in materials science, including various nano-materials.
The p5 575 is probably the densest computing node in the computing, cramming four 1.9 GHz, dual-core Power5 processors into a 2U rack-mounted chassis. (While this is great, a rack full of p5 575s also consumes 83.2 kilowatts of juice.) The Max Planck Society already has a cluster of 32 big pSeries SMP servers that delivers just over 5 teraflops of computing power.
