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 U.S. Department of Energy announced a new supercomputing program on Monday that could be worth up to $1.8 billion and deploy two systems, with one at Oak Ridge National Laboratory, that would be 50 to 100 times more powerful than today’s computers.

The new systems are called exascale computers. DOE said the new supercomputers will solidify United States leadership in exascale computing.

The initiative was announced by U.S. Energy Secretary Rick Perry in Washington, D.C., on Monday. Perry announced a request for proposals, or RFP, for the development of at least two new exascale supercomputers to be deployed at DOE national laboratories sometime around 2021-2023.

“The new supercomputers funded through this RFP will be follow-on systems to the first U.S. exascale system authorized by Secretary Perry this past June, named Aurora, which is currently under development at Argonne National Laboratory and scheduled to come online in 2021,” a press release said. The RFP announced Monday envisions the possibility of upgrades to Aurora or even a follow-on system in 2022-2023, “depending on an assessment of needs and opportunities at that time.” [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…]

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…]

A new 200-petaflop supercomputer will succeed Titan at Oak Ridge National Laboratory, and it could be available to scientists and researchers in 2018, a spokesperson said this week.

The new IBM supercomputer, named Summit, could about double the computing power of what is now the world’s fastest machine, a Chinese system named Sunway TaihuLight, according to a seminannual list of the world’s top supercomputers released in June.

Sunway TaihuLight is capable of 93 petaflops, according to the list, the TOP500 list. A petaflop is one quadrillion calculations per second. That’s 1,000 trillion calculations per second.

Summit, which is expected to start operating at ORNL early in 2018, is one of three supercomputers that the U.S. Department of Energy expects to exceed 100 petaflops at three U.S. Department of Energy laboratories in 2018. The three planned systems are:

the 200-petaflop Summit at ORNL, which is expected to be available to users in early 2018;
a 150-petaflop machine known as Sierra at Lawrence Livermore National Laboratory near San Francisco in mid-2018; and
a 180-petaflop supercomputer called Aurora at Argonne National Laboratory in Chicago in late 2018.

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…]
