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…]

Former director Alvin Weinberg once called it the greatest technical achievement at Oak Ridge National Laboratory. It was inspired by the campaign to build a nuclear-powered aircraft in the 1950s, and it was the first reactor to ever operate using uranium-233.

Now parts of the Molten Salt Reactor Experiment that are too radioactively “hot” for humans could be entombed in concrete.

For now, the idea is only under study, and there is no guarantee that any part of the Molten Salt Reactor Experiment, a nuclear historic landmark that has been dormant for decades, will be entombed.

But it’s one of the proposals being evaluated by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. The goal is to finish the evaluation by the end of the year.

Jay Mullis, manager of the Oak Ridge Office of Environmental Management, presented the proposal to the Oak Ridge City Council and Site Specific Advisory Board in two separate meetings earlier this month. The entombment proposal is one of five items being evaluated as part of a 45-day review started by DOE’s Environmental Management, or EM, program in June. [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…]

There has been strong interest in a voluntary separation program that could reduce the workforce at Oak Ridge National Laboratory by up to 350 positions, but the lab still has to review applications and finalize who qualifies, a spokesperson said Wednesday, the deadline to apply.

The laboratory is still in the middle of reviewing the applications and determining who qualifies, said Morgan McCorkle, ORNL communications media manager.

The workforce could be reduced by up to 350 positions through both voluntary and involuntary separations.

“We still expect to use both mechanisms,” McCorkle said.

The 350-position reduction would decrease the workforce of 4,800 employees by about 7.3 percent. The workforce reduction, which is expected to be completed by the end of this year, was announced by ORNL Director Thomas Zacharia in an August 8 email to employees. [Read more…]

Data collection systems at Oak Ridge National Laboratory are being used to help emergency responders and recovery crews with two deadly hurricanes, Harvey and Irma.

The data collection systems are LandScan USA and EAGLE-I. Information from the systems is being used by the Federal Emergency Management Agency and U.S. Department of Homeland Security, among other agencies. The two systems give information on electric customer outages and population counts, and they are being used in daily briefings, according to ORNL staff members.

The first system, LandScan USA, shows population counts with a resolution of about 90 meters. The system can show color-coded maps with population counts ranging for high to low, and it includes daytime and nighttime populations.

Flood maps can be overlaid on the population count maps to help determine the best places for rescuers to respond, said Amy Rose, ORNL team lead in Population Distribution and Dynamics. Rose displayed that map and overlay during an interview in the EVEREST visualization laboratory at ORNL on Tuesday.

Houston, which experienced heavy flooding, didn’t evacuate before Hurricane Harvey, a category 4 storm that came ashore just northeast of Corpus Christi, Texas, on Friday night, August 25. [Read more…]

New mapping methods developed by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory can help urban planners minimize the environmental impacts of cities’ water and energy demands on surrounding stream ecologies, a press release said.

In an analysis published in Proceedings of the National Academy of Sciences, an ORNL-led team used high-resolution geospatial modeling to quantify the effects of land, energy, and water infrastructures on the nation’s rivers and streams.

Using streamflow data from the U.S. Geological Survey, the researchers mapped changes to natural hydrology to assess how infrastructure development and competition over water resources affects the environment at a national scale. Their data-driven approach sheds light on the extent to which water resources and aquatic species are affected by urban infrastructures and could help cities curb their burden on regional ecosystems, the press release said.

The results indicate that urban land transformation and electricity production together affect 7 percent of U.S. streams, which influence habitats for more than 60 percent of all North American freshwater fish, mussel, and crayfish species, the release said. [Read more…]

The workforce reduction of up to 350 positions at Oak Ridge National Laboratory is expected to decrease personnel costs by about $34 million each year, and the lab expects most of those who apply for voluntary separations from the lab to be of retirement age, a spokesperson said Wednesday.

The workforce reduction, which is expected to be completed by the end of this year, was announced by new ORNL Director Thomas Zacharia in a Tuesday morning email to employees.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said in that email.

The lab hopes to reduce its workforce of 4,800 employees by about 7.3 percent (350 positions) using voluntary separations. Involuntary separations will be used if necessary.

On Wednesday, ORNL spokesperson Morgan McCorkle said the lab plans to reduce about 250 overhead positions and 100 research and development jobs. Overhead jobs are those not directly related to research. The research and development staff who will be eligible for voluntary separations are those who charge more than half of their time to overhead accounts or whose program budgets were reduced in fiscal year 2017, McCorkle said.

A specific breakdown of the affected jobs is not yet available. [Read more…]

Oak Ridge National Laboratory will reduce its workforce by up to 350 positions by the end of the calendar year, ORNL Director Thomas Zacharia said in a Tuesday morning email to employees.

The workforce restructuring plan has been proposed by UT-Battelle and approved by the U.S. Department of Energy, Zacharia said. ORNL is DOE’s largest multiprogram science and energy laboratory.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said. “To allow us to provide for our research missions and to allocate resources most productively, the Department of Energy has approved a Workforce Restructuring Plan proposed by UT-Battelle that will reduce ORNL’s workforce by up to 350 positions by the end of the calendar year.”

Zacharia said the reductions will be made primarily among staff who charge to “indirect accounts,” along with some research staff affected by fiscal year 2017 funding who could not be placed elsewhere in the lab.

“By reducing these positions, ORNL will be able to maintain competitive chargeout rates while freeing resources for discretionary investments that will modernize lab infrastructure and maintain core research capabilities in the mission areas assigned to ORNL,” Zacharia said. [Read more…]

The U.S. Navy teamed up with Oak Ridge National Laboratory to print the military’s first 3D-printed submersible hull in just four weeks. The parts were printed in just days, rather than weeks, and production costs were cut by 90 percent.

The hull was printed at ORNL’s Manufacturing Demonstration Facility in Hardin Valley through a partnership with the Navy’s Disruptive Technology Lab, according to a story published July 20 by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy. ORNL is a DOE laboratory.

“ORNL and the Navy saw this is as an opportunity to bring together their resources and expertise in a partnership with the potential to revolutionize manufacturing in the defense sector,” the DOE story said. “Not only can the Navy find new ways to reduce traditional costs associated with manufacturing, but the lessons learned from this project will help ORNL further explore 3D printing applications in the boating industry, aerospace, buildings, and anything that requires a large, resilient structure. Partnerships like these help drive economic growth and reinforce our national security.”

The team working on the 3D-printed submersible hull needed to create a 30-foot proof-of-concept hull out of carbon fiber composite material, DOE said. The prototype vessel is called the Optionally Manned Technology Demonstrator, and it could be used to deploy logistics capabilities and sensors. Future vessels will need to be manufactured faster and incorporate new designs to support Navy missions, DOE 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…]
