IBM tops Japanese supercomputer

IBM's BlueGene/Q system, installed at the Department of Energy’s Lawrence Livermore National Laboratory, tops the list of world's fastest supercomputers released today. The previous record was held by Fujitsu’s “K Computer” since early 2011, which clocks in at 10.51 Pflop/s on benchmark tests using 705,024 SPARC64 cores. The latest IBM computer achieves 16.32 petaflop/s on same benchmark using 1,572,864 cores. Seventy-five percent of the chips in the top supercomputers on the list were manufactured by Intel.
