The HPC Triple Crown [HPCWIRE]

Dec. 1, 2012, 2:45 a.m.

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.

Oak Ridge Claims No. 1 Position on Latest TOP500 List with Titan

Nov. 12, 2012, 8:32 a.m.

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.

Erich Strohmaier Writes Article on how the TOP500 List Gives Insight into HPC Industry

Sept. 26, 2012, 6:04 p.m.

Erich Strohmaier, a founding editor of the TOP500 list and leader of Future Technologies Group at Lawrence Berkeley National Laboratory, has written a cover story for Scientific Computing magazine on how the twice-yearly TOP500 list of the world’s top supercomputers provides a good look at the state of HPC technology.

About a Golden October and Autumn Leaves

Sept. 26, 2012, 4:58 a.m.

It's an old tradition: Where Intel shows off its products and roadmaps, AMD is not far off. At the IDF, Intel could boast the new Haswell processor – but its launch is still nine months away. AMD intends to crank it up right away.

About Old Chestnuts and New Challenges

Intel invests heavily in Europe, AMD faces mounting problems, the entire industry pins its hope on Windows 8 and Apple promises the workstation community something really big – for later.
