The TOP500 list of the world's most powerful supercomputers was released at the International Supercomputing Conference this week. And IBM hogged the top slots. The chipmaker claimed first place. And second. And third.
IBM's "Roadrunner" supercomputer won the title of the world's most powerful supercomputer. The Roadrunner, which is installed at the U.S. Department of Energy's Los Alamos National Laboratory, achieved a peak performance of 1.026 petaFLOPS, running past IBM's BlueGene L and P systems to claim first place.
Roadrunner is a hybrid processor that combines Cell Broadband Engine with AMD's Opteron dual-core processors, making it one of the most energy-efficient on the list.
The former holder of the title, Blue Gene/L at DOE's Argonne National Laboratory, came in second this year with a performance of 478.2 teraFLOPS. IBM also grabbed third place with the Team Blue Gene/P system at the Department of Energy's Argonne National Lab in Chicago.
Also at the top of list were Sun's SunBlade x6420 "Ranger" system at the University of Texas, and the Cray Xt4 "Jaguar" system at Oak Ridge National Lab in Tennessee.
While IBM claimed the top slots, Intel continued to dominate the list, with Intel processors now found in 75 percent of the TOP500 supercomputers, up from 70.8 percent of the 30th list released last year.
