The supercomputer being built at Oak Ridge National Laboratory could change the race for supercomputing supremacy between the United States and China, U.S. Representative Chuck Fleischmann said during a budget hearing on Thursday.

The congressman said Summit, a 200-petaflop supercomputer at ORNL, will be commissioned this summer, and it will be the fastest supercomputer in the world, with twice the power of the top Chinese system. The Chinese machine is a 93-petaflop system known as Sunway TaihuLight.

During Thursday’s budget hearing, which featured Energy Secretary Rick Perry, Fleischmann said the United States and China are in a race for supercomputing supremacy. The race is critical to advances in science and technology that will drive economic growth, said Fleischmann, a Republican whose district includes Oak Ridge.

Citing a February 9 edition of Science magazine, Fleischmann said the U.S. dominated supercomputer rankings for decades but is now far behind. The combined power of the top two machines in China easily outpaces all 21 supercomputers operated by the U.S. Department of Energy, the country’s top funder of supercomputers, the congressman said.

But that could change with the commissioning of Summit this summer, Fleischmann said. [Read more…]

China has passed the United States in the total number of top ranked supercomputers, and Titan at Oak Ridge National Laboratory has dropped from fourth to fifth on the TOP500 list of the world’s fastest supercomputers.

The TOP500 list is released twice a year, once in June and once in November. It is based on a benchmark test known as Linpack.

Titan at ORNL dropped from third to fourth in June, bumped from the number three spot by the upgraded Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre. Titan is capable of 17.59 petaflops. A petaflop is one quadrillion calculations per second. That’s 1,000 trillion calculations per second. Piz Daint is capable of 19.59 petaflops.

That power is useful in scientific research. At ORNL, Titan is used for research in areas such as materials science, nuclear energy, combustion, and climate science. ORNL is a U.S. Department of Energy laboratory.

Titan slipped one more spot in this month’s list, from fourth to fifth. It was displaced by the upgraded Gyoukou supercomputer. That is a ZettaScaler-2.2 system capable of 19.14 petaflops and deployed at Japan’s Agency for Marine-Earth Science and Technology, the home of the Earth Simulator. [Read more…]

Oak Ridge National Laboratory on Wednesday said it is building the world’s smartest supercomputer.

The new supercomputer is called Summit. It will be located in a new data center next to Titan, which is now the fourth most powerful supercomputer in the world.

Summit will be 5-10 times faster than Titan, ORNL said. It will move data five to 10 times faster, store eight times more data, and perform many more calculations simultaneously than Titan, the lab said in information provided by spokesperson Morgan McCorkle.

Summit will be the world’s smartest supercomputer because of its enormous memory and data handling capabilities as well as its unique machine learning processor design, McCorkle said.

“The first of Summit’s cabinets arrived Monday, and our team is in the process of uncrating and putting them in place,” McCorkle said in response to questions from Oak Ridge Today. [Read more…]

Once the world’s most powerful supercomputer, Titan at Oak Ridge National Laboratory dropped to number four on a list of the world’s most powerful supercomputers released Monday.

Titan, a Cray XK7 system, was bumped from the number three spot by the upgraded Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre.

China continues to have the world’s two most powerful supercomputers.

The TOP50 List of the world’s most powerful supercomputers is based on a benchmark test known as Linpack. The list is released twice each year, once in June and again in November. The 49th edition of the TOP500 List was released Monday in conjunction with the opening session of the ISC High Performance conference, which is taking place this week in Frankfurt, Germany.

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…]
