For the first time since 2012, the United States has the most powerful supercomputer in the world, and it’s again located at Oak Ridge National Laboratory.

The new supercomputer, called Summit, is capable of 200 petaflops, or 200,000 trillion calculations per second. Equipment delivery for Summit was completed in March, and officials celebrated the launch of the supercomputer in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8.

The last time the United States had the top supercomputer was in November 2012. That machine, which is still in use, is named Titan, and it’s also at ORNL. It’s now number seven on the semiannual TOP500 list, which was released Monday.

China had held the top spot since June 2013, and the country had held the top two spots since June 2016. That ended with Monday’s TOP500 announcement. Previously at number one and number two, the top two Chinese supercomputers have fallen to number two and number four.

ORNL, a U.S. Department of Energy laboratory, now has two of the top seven systems on the list. They are Summit at number one and Titan at number seven. The United States now has six of the top 10 machines, according to the TOP500 list. [Read more…]

Oak Ridge National Laboratory again has the world’s most powerful supercomputer. It’s also the world’s smartest supercomputer, a machine that can learn—and run software that will write software.

The supercomputer, called Summit, is capable of 200 petaflops, or 200,000 trillion calculations per second. During a Friday afternoon ceremony, U.S. Energy Secretary Rick Perry said Summit can save 30 years worth of desktop data in one hour. It is millions times faster than a really good high-end desktop, said Ginni Rometty, IBM chair, president, and chief executive officer.

A water-cooled IBM system, Summit is presumed to have bumped China from the top spot, at least among open-science systems or supercomputers that aren’t classified. It has successfully run the world’s first exascale scientific calculation.

“We know we’re in competition, and it matters who gets there first,” Perry told several hundred people at the Friday afternoon ceremony at ORNL, a U.S. Department of Energy laboratory. “We reached a pinnacle today.”

Researchers at ORNL could find the cure for Alzheimer’s disease or cancer, Perry said. Winning the global supercomputing race could have benefits for all of humanity, said Jensen Huang, NVIDIA founder, president, and CEO. [Read more…]

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…]

U.S. Department of Justice

KNOXVILLE—On Thursday, Szuhsiung Ho, also known as Allen Ho, 66, a naturalized U.S. citizen, was sentenced by Chief U.S. District Judge Thomas A. Varlan to serve 24 months in prison and one year of supervised release. Upon his release, he will be supervised by U.S. Probation for one year. He was also ordered to pay a fine of $20,000.

Ho pleaded guilty in January 2017 to conspiracy to unlawfully engage or participate in the production or development of special nuclear material outside the United States, without the required authorization from the U.S. Department of Energy, in violation of the Atomic Energy Act, a press release said.

An April 2016 indictment charged Ho; China General Nuclear Power Company (CGNPC), the largest nuclear power company in China; and Energy Technology International (ETI), a Delaware corporation, with these offenses. At the time of his indictment, Ho was a nuclear engineer, employed as a consultant by CGNPC, and he was also the owner of ETI. CGNPC specialized in the development and manufacture of nuclear reactors and was controlled by China’s State-Owned Assets Supervision and Administration Commission, the press release said.

China still has the two fastest supercomputers in the world, and Titan at Oak Ridge National Laboratory remains number three.

The semi-annual TOP500 List of the world’s top supercomputers was released last Monday, November 14, at a conference in Salt Lake City.

Titan, a Cray XK7 system installed at ORNL, a U.S. Department of Energy laboratory, has achieved 17.59 petaflops, or quadrillions of calculations per second.

The most powerful supercomputer, a relatively new Chinese supercomputer named Sunway TaihuLight, is capable of 93 petaflops. It is built entirely using processors designed and made in China. In June, it displaced Tianhe-2, an Intel-based Chinese supercomputer that had claimed the number one spot on the six previous TOP500 lists.

Tianhe-2, the number two system, achieved a speed of 33.86 petaflops, or more than 33,000 trillion calculations per second, in a test known as the LINPACK benchmark. That ranking program uses a series of linear equations to test computer systems around the world. [Read more…]

China maintained its number one ranking in the latest edition of the TOP500 list of the world’s top supercomputers, but with a new system built entirely using processors designed and made in China.

China now has the top two supercomputers on the semiannual TOP500 list, and Titan at Oak Ridge National Laboratory has dropped from number two to number three.

The new Chinese supercomputer, Sunway TaihuLight, is capable of 93 petaflops, or quadrillions of calculations per second, a press release said.

It displaced Tianhe-2, an Intel-based Chinese supercomputer that had claimed the number one spot on the past six TOP500 lists. Tianhe-2 achieved a speed of 33.86 petaflops, or more than 33,000 trillion calculations per second, in a test known as the LINPACK benchmark.

Titan, a Cray XK7 system installed at ORNL, a U.S. Department of Energy laboratory, achieved 17.59 petaflops.

Titan was the top system for a short time. It was number one in November 2012, but it was bumped to number two behind Tianhe-2 in June 2013. This is the first time it has been number three.

The latest list marks the first time since the start of the TOP500 that the United States is not home to the largest number of systems. With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the U.S. is second with 165. China also leads the performance category, thanks to the number one and number two systems, the press release said. [Read more…]

A Chinese supercomputer kept its No. 1 spot, and Titan at Oak Ridge National Laboratory stayed at No. 2 in the latest semiannual ranking of the world’s most powerful supercomputers.

The Chinese supercomputer, Tianhe-2, was developed by China’s National University of Defense Technology, and it’s been in the top spot three times in a row on the Top500 List. Tianhe-2 bumped Titan from the top spot in June 2013.

The Chinese supercomputer performed at 33.86 petaflops—that’s 33.86 quadrillion calculations per second—on a test known as the Linpack benchmark, the press release said. Titan performed at 17.59 petaflops.

There was little change among the ranking of the world’s Top 10 supercomputers in the latest edition of the closely watched list, a press release said. The only new entry was at number 10—a 3.14-petaflop Cray XC30 installed at an undisclosed U.S. government site.

The Top500 list was announced Monday morning. The list is compiled by Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee in Knoxville, and Martin Meuer of Prometeus, Germany. [Read more…]
