IT Infrastructure: IBM, Fujitsu Top List of the World's 500 Fastest Supercomputers
Sequoia Put U.S. Back on Top
IBM's Blue Gene/Q supercomputer at the Lawrence Livermore National Laboratory hit a performance of 16.32 petaflops, putting the United States back on top of the Top 500 for the first time in almost three years. Sequoia, which is powered by more than 1.5 Power processing cores, also is the most energy-efficient system on the list.
The United States regained the No. 1 spot on the list of the top 500 fastest supercomputers, thanks to IBM's massive Sequoia Blue Gene/Q system installed at the Lawrence Livermore National Laboratory. The system hit a maximum performance of 16.32 petaflops, sprinting past last year's fastest system, Fujitsu's K Computer, which had a top performance of 10.51 petaflops. The designation was made June 18 with the unveiling of the latest Top500 list of the fastest supercomputers, which is released twice a year. The last time the United States was at the top of the list was in November 2009, and it is home to 253 of the 500 supercomputers. Intel saw the number of systems running its technology drop slightlyfrom 384 in November 2011 to 372 on this list. But it also touted wide adoption of its new Xeon E5-2600 processors, which were released in March and now account for 44 of the supercomputers on the list, including the fourth- and ninth-fastest ones. IBM remained the top vendor on the list, with 213 supercomputers. Hewlett-Packard was second with 138 systems, followed by Cray, Appro, SGI and Bull.
