“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.”
