"Everyone who follows super-computers knows that they run on Linux. Just one look at the latest Top 500 SuperComputer list confirms that. Today 91.8% of all super-computers run Linux. Alas, if you look at the latest list, you'll also see that the U.S. now trails China in the super-computers. IBM's new CMOS Integrated Silicon Nanophotonics chips, though, should soon put the U.S. back in the lead.

"Today the fastest of the fast computers is the Tianhe-1A Running full-out, it hits a peak performance of 2.57 petaflop/s (quadrillions of calculations per second).and cruises along at 563.1 teraflops. To do this, it uses 14,336 Intel Xeon CPUs and 7,168 NVIDIA Tesla GPUs and Linux.

"That's impressive. The Tianhe-1A easily races past the Cray XT5 "Jaguar" system at the U.S. Department of Energy's (DOE) Oak Ridge Leadership Computing Facility in Tennessee. That Cray XTS super-computer is now ranked in second place at 1.75 petaflop/s."
