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. 

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.

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 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.
