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…]

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…]

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have received nine R&D 100 Awards in recognition of their significant advancements in science and technology, a press release said. The honorees were recognized in November at the 55th annual R&D 100 Conference, sponsored by R&D Magazine.

The awards, known as the “Oscars of Invention,” honor innovative breakthroughs in materials science, biomedicine, consumer products, and more from academia, industry, and government-sponsored research agencies. This year’s nine honors bring ORNL’s total of R&D 100 awards to 210 since their inception in 1963, the press release said.

ORNL researchers were recognized for the following innovations:

ACMZ Cast Aluminum Alloys were developed by a team of researchers from ORNL with Fiat Chrysler Automobile U.S. and Nemak U.S.A.

ACMZ aluminum alloys are a new class of affordable, lightweight superalloys capable of withstanding temperatures of almost 100-degree Celsius more than current commercial alloys while providing exceptional thermomechanical performance and hot tear resistance.

Common commercial alloys soften rapidly at high temperatures, limiting their use in next-generation vehicles, while other alloys that can withstand elevated temperatures are cost prohibitive and difficult to cast. ACMZ alloys were developed using a suite of atomic-level characterization and computation tools, resulting in a strong, stable, and versatile material capable of withstanding the stressful conditions of next-generation high-efficiency combustion engines, the press release said.

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…]

DOE, NNSA computing project names new director, to be based at ORNL

Doug Kothe

A collaboration between the U.S. Department of Energy and the National Nuclear Security Administration has named a new director of the project to build computing systems that are at least 50 times faster than the nation’s most powerful supercomputers in use today—and the new director will be based at Oak Ridge National Laboratory.

The collaborative project is the Exascale Computing Project. It’s a collaboration between DOE’s Office of Science and the NNSA, which is a semi-autonomous agency within DOE.

The new director is Doug Kothe, a 32-year veteran of DOE’s national laboratory system who most recently served in ORNL’s Computing and Computational Sciences Directorate and as the applications development lead for the Exascale Computing Project, or ECP. For the preceding five years, he led the Consortium for Advanced Simulation of Light Water Reactors, DOE’s first Energy Innovation Hub, which uses supercomputers to improve nuclear reactor performance.

Kothe will be ECP director effective October 1. He will replace Paul Messina, who is stepping down after two years to return to Argonne National Laboratory, a press release said. [Read more…]

In a first-of-a-kind experiment, researchers used neutrons to investigate the performance of a new aluminum alloy in a gasoline-powered engine—while the engine was running.

A team from the U.S. Department of Energy’s Oak Ridge National Laboratory worked with industry partners to perform the test, which looked at whether a high-performance alloy that is promising for automotive applications held up under the heat and stress of an internal combustion engine.

Researchers used neutrons to probe a running engine at ORNL’s Spallation Neutron Source, giving them the opportunity to test an aluminum-cerium alloy under operating conditions.

The feat was a first for the Spallation Neutron Source, said Ke An, lead instrument scientist for the facility’s VULCAN instrument.

“This was the first time an internal combustion engine has been run on our diffractometer, and, as far as we know, on any other,” he said. [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…]

If excess funding is available, the federal cleanup program in Oak Ridge has a top priority: the Biology Complex at the Y-12 National Security Complex.

The budget request submitted to Congress by President Donald Trump on Tuesday, May 23, included $225 million for high-risk excess contaminated facilities at Y-12 and Lawrence Livermore National Laboratory in California.

It’s not clear how much of that money might be used in Oak Ridge, if the president’s budget request were approved. Officials said the allocations would be determined by U.S. Department of Energy headquarters.

But the Oak Ridge cleanup program, known as environmental management, has taken steps to ensure that some projects here, such as the planned demolition of Y-12’s Biology Complex, are “in a good position” if money becomes available.

On Friday, Jay Mullis, acting manager for the DOE Oak Ridge Office of Environmental Management, or EM, said the Biology Complex would be a primary priority if Y-12 gets some portion of the $225 million proposed by the Trump administration.

“Provided there is excess funding, that would be the building we would go after,” the Oak Ridge EM program said. [Read more…]

Cleanup funding could be up for the U.S. Department of Energy under the budget request from the Trump administration for fiscal year 2018, and there could be benefits for Oak Ridge, according to budget documents.

President Donald Trump submitted his budget request to Congress on Tuesday, May 23. In that request, the DOE Office of Environmental Management, or EM, asked for $6.5 billion, the largest request in a decade. That would be $290 million above fiscal year 2016.

The funding request for Oak Ridge includes $390 million, or $78 million below fiscal year 2016, to continue deactivation and demolition of remaining facilities at East Tennessee Technology Park, continue preparing Building 2026 to support the processing of the remaining U-233 material at Oak Ridge National Laboratory, and to support activities for the Mercury Treatment Facility at Y-12 National Security Complex.

It’s not clear whether that $390 million in the funding request includes part of the $225 million in funding requested for high-risk excess contaminated facilities at Y-12 and Lawrence Livermore National Laboratory in California. It’s also not clear whether the total funding for Oak Ridge cleanup programs would be up or down, compared to previous years. The DOE public affairs office in Washington, D.C., has not responded to about a dozen budget-related inquiries from Oak Ridge Today since May 23.

Among the highlights of the EM request for Oak Ridge, according to budget documents posted online by DOE and an EM press release: [Read more…]

Funding for the Y-12 National Security Complex in Oak Ridge would be up about 25 percent under the budget request submitted to Congress in May, according to the National Nuclear Security Administration.

The total funding for Y-12 would be $1.64 billion, the NNSA said. That’s an increase of 25.4 percent over fiscal year 2016.

The budget request for fiscal year 2018, which starts October 1, was submitted by President Donald Trump to Congress on Tuesday, May 23. The NNSA request of $13.9 billion would increase funding by 7.8 percent compared to fiscal year 2017, Administrator Frank G. Klotz said during a teleconference with reporters on May 23.

Trump’s budget request has not yet been approved by Congress, where there has been bipartisan opposition, particularly to the proposed cuts. In Oak Ridge, sites and programs that could be cut include Oak Ridge National Laboratory, which would have a funding reduction of $206 million over two years, and the U.S. Department of Energy’s Energy Efficiency and Renewable Energy, or EERE.

But Y-12, a National Nuclear Security Administration site, could benefit if the president’s budget request were approved by Congress. A House spending bill introduced last week for federal energy and water departments appears to include proposed spending levels for the NNSA, a semi-autonomous agency within DOE, that are similar to what the Trump administration has proposed.

Tennessee Governor Bill Haslam visited the U.S. Department of Energy’s Oak Ridge National Laboratory on Friday to congratulate the ORNL team involved in the discovery of the element tennessine, named in recognition of the vital contributions of the state of Tennessee to the international search for new superheavy elements.

UT-Battelle, the managing contractor of ORNL, is marking the discovery by providing more than 1,000 public middle schools and high schools in Tennessee with new charts of the periodic table. Tennessine—the official name for element 117—completes the seventh row of the table and the column of elements classified as halogens.

The charts will include the signatures of Haslam and ORNL Director Thom Mason.

“We had two very significant announcements in Tennessee this fall as it relates to science,” Haslam said. “In October, the Nation’s Report Card announced that Tennessee students are the fastest improving in the nation in science, and in November, Tennessee became only the second state to be recognized in the periodic table of elements. Having an element named in our honor is further evidence of the scientific excellence that exists at Oak Ridge National Laboratory, the University of Tennessee, Vanderbilt University, and other institutions throughout our state, and by UT-Battelle donating new periodic tables to every middle and high school in Tennessee, students can feel proud of our state’s important role in the scientific community and inspired to play a role in its future.” [Read more…]

Name of new element, tennessine, recognizes state’s contributions, including at ORNL

By Oak Ridge Today Staff Leave a Comment

The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the U.S. Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.

“The presence of tennessine on the Periodic Table is an affirmation of our state’s standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory’s scientists and technicians,” ORNL Director Thom Mason said in a press release.

The International Union of Pure and Applied Chemistry, or IUPAC, gave its final approval to the name “tennessine” following a year-long process that began December 30, 2015, when IUPAC and the International Union of Pure and Applied Physics announced verification of the existence of the superheavy element 117. That was more than five years after scientists first reported its discovery in April 2010.

IUPAC validates the existence of newly discovered elements and approves their official names.

ORNL had several roles in the discovery, the most prominent being production of the radioisotope berkelium-249 for the search. [Read more…]
