TOP500 Systems and Exascalar Efficiency, Part II (Datacenter Knowledge)
Intel’s Winston Saunders with Part II of his feature piece on how the most recent Top500 and Green500 machines stack up in terms of Exascalar, the “logarithmic distance” to 1018 flops in a 20 MegaWatt power envelope.
Exascalar Results from November 2012: Part 1 (Datacenter Knowledge)
With the recent publication of the Top500 and Green500 lists of the world’s most powerful and efficient supercomputers, Intel’s Winston Saunders pulls together another look at Exascalar.
About Bugs, Bidders and Batmen
The new year begins like the old year ends: Delays with Windows tablets, bugs in hardware and software and glimpses of new – naturally much better – chips, like Nvidia's Wayne.
About Possible Foundries and Impossible Processes
The start of December is when the International Electron Devices Meeting IEDM traditionally takes place. Next to the presentation of numerous new designs (with and without silicon), its agenda always includes an overview of the latest process technology.
The HPC Triple Crown [HPCWIRE]
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.
TOP500 Slides from SC12 are now available
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.
Oak Ridge Claims No. 1 Position on Latest TOP500 List with Titan
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.
TOP500 List to Mark 20th Anniversary at SC12 in Salt Lake City
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?
About Assumptions and Acquisitions
The PC market is in a tailspin and many companies have to announce very poor results – and yet, we also have some winners. AMD is definitely not among them, a mass layoff looms on the horizon. And, again, take-over rumors are circulating.
About Memristors and Other Cannibals
The back to school season starts with many new processors, although IBM's large server chips probably don't have much to do with the end of the holidays. And there are going to be a few delays – maybe with AMD's Steamroller and for sure with HP's memristor.
