Chinese supercomputer still No. 1, ORNL’s Titan No. 2

A Chinese supercomputer kept its top ranking, and Titan at Oak Ridge National Laboratory stayed at No. 2 in a Top 500 ranking of the world’s most powerful supercomputers released Monday morning.

The top two spots were unchanged from the semiannual rankings released five months ago in June, when Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, bumped Titan from the top spot. The ORNL supercomputer had been named No. 1 one year ago.

The rankings released Monday at the SC13 conference in Denver, Colo., said Tianhe-2 is capable of performing 33.86 petaflops. That’s 33.86 quadrillion calculations per second, on what is known as a Linpack benchmark test.

Titan is a Cray XK7 system that achieved 17.59 petaflops. Titan is one of the most energy-efficient systems on the list, consuming a total of 8.21 megawatts and delivering 2.143 gigaflops per watt, a press release said. [Read more…]

A Chinese supercomputer has bumped the Titan supercomputer at Oak Ridge National Laboratory from the No. 1 spot on a semiannual ranking of the world’s most powerful supercomputers.

The Tianhe-2, which was developed by China’s National University of Defense Technology, is capable of 33.86 petaflops, or more than 33,000 trillion calculations per second.

Now ranked No. 2, Titan was able to perform 17,000 trillion calculations per second, or 17.59 petaflops, according to the list published in November. [Read more…]
