The Verge: There's a new leader on top of the list of the world's 500 fastest supercomputers: an IBM system called "Sequoia" reached a sustained 16.32 sustained petaflops. That easily bested the previous champ, Fujitsu's K computer, which hit 10.51 petaflops.
IBM built the Sequoia for the National Nuclear Security Administration (NNSA). It sits across 96 racks and has 98,304 compute nodes, 1.6 million cores and 1.6 petabytes of RAM.
