IBM system uses 98,000 nodes, 1.5 million cores
A supercomputer in the United States tops the list of the world's top 500 for the first time since November 2009. Sequoia, an IBM Blue Gene/Q system installed by the Lawrence Livermore National Laboratory for the Department of Energy, clocked in at 16.32 sustained petaflops during tests, 50 percent more powerful than the second place “K Computer” in Japan.
Takes top spot from Chinese supercomputer
A computer developed by Fujitsu and the RIKEN Advanced Institute for Computational Science has claimed the title of the world's most powerful supercomputer on the Top500 list. The Fujitsu K Computer is a series of 672 computer racks with a total of 68,544 CPUs. The K Computer handles 8.162 petaflop/s (quadrillion floating point operations per second) as measured by the LINPACK benchmark. Researchers expect the final configuration of the K Computer to exceed 10 petaflop/s. The supercomputer it bumped from the top spot, the Tianhe-1A supercomputer at the National Supercomputing Center in Tianjin, China, performs 2.6 petaflop/s.
