Supercomputer with 68,000+ CPUs is world's fastest
According to TOP500.Org, the Fujitsu-built “K computer” in Kobe, Japan, is currently the world’s fastest supercomputer. Able to complete more than 8 quadrillion calculations per second (petaflop/s), the K computer uses 672 computer racks and 68,544 SPARC64 VIIIfx CPUs–with eight cores each.
Although only the K computer is only half finished, it was able to achieve a LINPACK benchmark performance of 8.162 petaflops. When completed in 2012, the K computer will have over 800 racks, and be designed to reach 10 petaflops.
Also, Linux rules!
While Linux still has trouble getting a grip on the desktop, everywhere else Linux rules. No where is that clearer than it is in the fastest of the fast: the supercomputers.
In the latest Top 500 Supercomputer list list, which was released on June 20th, Linux accounts for 91.00 % of the top supercomputers. Linux is followed by Unix with 4.6%; and Windows with 1.2%. When it comes to super-fast computers like supercomputers or IBM Jeopardy winning Watson, Linux rules.
