Ars technica has a brief look at the world's fastest x86-based supercomputer and Europe's fastest supercomputer‚ÄĒnot to mention the 4th most powerful in the world. The SuperMUC, which runs SUSE Linux, is located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. "A statement issued by SUSE says that the supercomputer has a unique cooling system inspired by human blood circulation that significantly reduces energy consumption. The supercomputer is reportedly designed so that some of the energy can be recaptured and used to heat buildings at the LRZ campus. The statement also says that the SuperMUC has 155,000 processor cores capable of delivering a total of 3 petaflops of processing power. A report on Slashdot indicates that the computer has 324 terabytes of memory."
