1IBM Roadrunner Dusts Cray Jaguar in World’s Fastest Supercomputer Race
The Top500 list of the world’s fastest supercomputers was released June 23 at the International Supercomputing Conference in Hamburg, Germany. Sitting atop the list–again–was IBM’s Roadrunner system, which runs at the Department of Energy’s Los Alamos National Laboratory. The IBM BladeCenter system took the top spot a year ago and has held on since. Also for the second year in a row, Cray’s XT5 Jaguar supercomputer, which runs at the DOE’s Oak Ridge National Laboratory, came in a close second. According to the Top500 organization, which compiles the list every June and November, two new entries into the top 10 come from Germany. Those two are the only systems in the top 10 not from the United States, which is still the top consumer of HPC (high-performance computing) systems in the world, with 291 of the top 500 systems running in this country. Along with IBM and Cray, Sun Microsystems and SGI also have systems listed in the top 10.
21. IBM Roadrunner
Based at the DOE’s Los Alamos National Laboratory, the BladeCenter cluster can process up to 1.105 petaflops per second (quadrillions of floating-point operations per second). The system in June 2008 became the first system ever to break the petaflop-per-second Linpack barrier, and is one of the most energy-efficient systems on the Top500, according to the list makers.
32. Cray XT5 Jaguar
43. Jugene – IBM Blue Gene/P
The IBM supercomputer is one of two German systems in the top 10. Installed at Forschungszentrum Juelich in Germany, the supercomputer has achieved 825.5 teraflops per second (trillions of floating-point operations per second) and has a theoretical peak performance of just above 1 petaflop per second, according to the Top500 list.
