World's Fastest Computer

IBM's Sequoia has officially become the world's fastest supercomputer. It is the first time the United States has taken the top spot since 2009, when it was overtaken by China. The IBM Sequoia BlueGene/Q supercomputer, installed at the Department of Energy's Lawrence Livermore National Laboratory, runs 16.32 petaflops, using 1.6 million compute cores in 96 racks, each roughly the size of a large refrigerator. Perhaps more significantly, the Sequoia supercomputer is water cooled.
