DOE flips switch on Titan, world’s newest fastest supercomputer | Ars Technica: "The Department of Energy's Oak Ridge National Labs today powered up Titan, a new supercomputer with 299,008 CPU cores, 18,688 GPUs, and more than 700 terabytes of memory. Titan is capable of a peak speed of 27 quadrillion calculations per second (petaflops)—ten times the processing power of its predecessor at Oak Ridge—and will likely unseat DOE's Sequoia supercomputer (an IBM BlueGene/Q system at Lawrence Livermore National Laboratory) as the fastest in the world."
