DoE supercomputer clocked as world's fastest2012-11-13 09:42 by DanielaTags: Titan, supercomputer
The U.S. Department of Energy Oak Ridge National Laboratory's newly installed Titan system, a Cray XK7, has been announced as the world's fastest supercomputer in the newly released 40th edition of the Top500 compilation of the world's fastest supercomputers. Titan is a Cray XK7 system that contains 18,688 nodes, each built from a 16-core AMD Opteron 6274 processor and an NVIDIA Tesla K20X GPU accelerator. It has 710 terabytes of memory. Its hybrid architecture, combining traditional CPUs with graphic processing units (GPUs) - is seen as a step toward exascale computing - generating 1,000 quadrillion calculations per second using 20 megawatts of electricity or less. Other systems in the Top 5 were Fujitsu's K computer at the RIKEN Advanced Institute for Computational Science in Kobe, Japan, which was No. 3; a BlueGene/Q system named Mira at Argonne National Laboratory near Chicago at No. 4; and a BlueGene/Q system named JUQUEEN at the Forschungszentrum Juelich in Germany, which placed fifth. However, scientists at Oak Ridge National Laboratory, said they are focused more on research than rankings. "We love being No. 1," said Bronson Messer, acting group leader for scientific computing at the National Center for Computational Science at ORNL. "It's great recognition. But what really matters is what science will do with the machine." Read more -here-
