IBM 'Roadrunner' Holds World's Fastest Computer Crown

IBM's "Roadrunner" supercomputer at the Los Alamos National Laboratory held on to its title as the world's fastest computer, followed once again by Cray's "Jaguar". IBM's "Roadrunner" has held this title since June 2008!

The biannual Top500 list, released Tuesday at the 2009 International Supercomputing Conference, also saw two new systems enter the top 10. Both systems -- the IBM BlueGene/P called Jugene and the Juropa, which is built from Novascale and Sun Microsystems Sun Blade x6048 server -- were at Forschungszentrum Juelich in Germany. The Jugene achieved 825.5 teraflops and the Juropa 274.8 teraflops. A teraflop is a trillion floating point operations per second. But the IBM Roadrunner remained the king with 1.105 petaflops. The system became the first to break the petaflop barrier in June 2008. The Cray XT5 Jaguar system at the Oak Ridge National Laboratory was a close second at 1.059 petaflops. A petaflop is a quadrillion floating point operations per second. IBM's Jugene entered the top 10 as No. 3.
