The semi-annual HPC "500 list" time and its attendant fall iron horse racing season are upon us. Thanks to the hard work of the list keepers, we currently enjoy three major ones to review, compare and contrast: TOP500, Green500 and Graph 500. Each focuses on a distinct aspect of HPC – number crunching, energy efficiency, and data crunching, respectively – and together they allow us to construct our own type of Triple Crown. Since new race results were recently announced, let's take a look at the current standings.
The slides from the TOP500 BoF Session at SC12 in Salt Lake City, Utah are now available. Special for this year was the presentation by Horst Simon of all systems that made it to the top of the list in the last 20 years and a special presentation by Hans Meuer about sites entering the list for the first time.
The TOP500 BoF session was held on November 13, 2012.
MANNHEIM, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—Advanced reports that Oak Ridge National Laboratory was fielding the world’s fastest supercomputer were proven correct when the 40th edition of the twice-yearly TOP500 List of the world’s top supercomputers was released today (Nov. 12, 2012). Titan, a Cray XK7 system installed at Oak Ridge, achieved 17.59 Petaflop/s (quadrillions of calculations per second) on the Linpack benchmark. Titan has 560,640 processors, including 261,632 NVIDIA K20x accelerator cores.
Do you remember the machine that took the first No. 1 position when the list debuted way back in 1993? Or how many consecutive lists were topped by the Earth Simulator? And when did Roadrunner make it into first place?
