China’s Tianhe-2 Supercomputer Takes No. 1 Ranking on 41st TOP500 List

MANNHEIM, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.--Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, is the world’s new No. 1 system with a performance of 33.86 petaflop/s on the Linpack benchmark, according to the 41st edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers. The list was announced June 17 during the opening session of the 2013 International Supercomputing Conference in Leipzig, Germany.

With Roadrunner's Retirement, Petascale Enters Middle Age

Maybe I'm getting old, but the petascale era of supercomputing still feels new to me. On the other hand, the recent decommissioning of IBM's Roadrunner, the world's first petaflopper, suggests otherwise. Roadrunner booted up at the Department of Energy's Los Alamos National Laboratory five years ago in 2008. Its retirement last week marks the approximate mid-point between the first petaflop system and the first exaflop one -- assuming, of course, you're an exascale optimist.

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?
