Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]

Starting in December, Oak Ridge National Laboratory and Y-12 National Security Complex will both manage their own security forces to protect their sites.

Y-12 has been managing its own protective force for about six years, ever since a former contractor, B&W Y-12, terminated a contract with WSI Oak Ridge after a security breach at the 811-acre plant. The current Y-12 contractor, Consolidated Nuclear Security LLC, confirmed this month that it has been responsible for security and security police officers since it began managing and operating the plant in July 2014.

On Friday, UT-Battelle, which manages and operates ORNL for the U.S. Department of Energy, said it is assuming responsibility for providing protective force services at the laboratory starting December 30. That’s when a new security contractor will take over at some federal sites in Oak Ridge.

ORNL Media Relations Manager Morgan McCorkle said about 90 employees who have been providing security services at ORNL under a contract with National Strategic Protective Services LLC will transition from NSPS to UT-Battelle. [Read more…]

The 200-petaflop Summit supercomputer at Oak Ridge National Laboratory stayed at number one on the semiannual TOP500 list of the world’s most powerful supercomputers released Monday.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, climbed to number two from number three. That means the United States now has the top two systems in the world, a position that China held a year ago.

Summit, a water-cooled IBM-built supercomputer, debuted at number one on the TOP500 list in June. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. The earlier top system, Titan, a Cray machine, is also located at ONRL. ORNL and LLNL are both U.S. Department of Energy laboratories.

Officials celebrated the launch of Summit in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8. The supercomputer is capable of 200 petaflops, or 200,000 trillion calculations per second. That makes it about about eight times more powerful than Titan, its predecessor.

Besides being the most powerful, Summit has been described as the world’s smartest supercomputer, a machine that can learn. As big as two tennis courts, Summit has 4,608 compute servers. Each has two 22-core IBM Power9 central processing units (CPUs) and six NVIDIA Tesla V100 graphics processing unit (GPU) accelerators. That’s more than 9,000 conventional processors and nearly 28,000 graphics processors, or about 37,000 total. [Read more…]

For the U.S. military, accurate weather prediction is vital to both the planning and execution of worldwide missions. To extend its weather modeling capabilities, the U.S. Air Force has joined the computing experts at the U.S. Department of Energy’s Oak Ridge National Laboratory in a strategic collaboration that includes procurement and operation of a new high-performance weather modeling computer system. Key members of the Air Force and ORNL teams, including computing and global security team members, gathered on July 10 to kick off this project and tour the facilities supporting the new system, according to a story posted by ORNL.

The Air Force 557th Weather Wing provides the Air Force and Army with global- and regional-level numerical weather model forecasts. With the increasing scale of the requirements for the new system, the Air Force and ORNL identified an opportunity to take advantage of the capabilities of ORNL’s National Center for Computational Sciences—including expertise in high-performance computing facilities and infrastructure, systems administration, computing procurement and acquisition, and system operations, the story said.

“We learned about the Air Force’s needs, and it was immediately clear that ORNL could help them solve their problems,” said Jim Rogers, NCCS director of computing and facilities. “We can integrate the Air Force weather team’s needs into our facilities in a cost-effective way, leveraging our capabilities to deliver exceedingly high availability to support their mission.” [Read more…]

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 final drums of old transuranic waste stored at Oak Ridge National Laboratory have been prepared for disposal.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management reported Tuesday that it had recently completed installing vents and sample ports in the final drums of the legacy transuranic waste stored at ORNL. The decade-long effort ensures that the drums do not contain any hazardous gases that could cause rapid combustion.

The ventilated unit where the drums were vented is closed and explosion-proof, DOE said. It is capable of withstanding a combustion event while keeping workers and ORNL, the nation’s largest multi-program national laboratory, safe, DOE said.

“Venting and sampling these drums is an essential part of the waste disposal process,” ORNL Portfolio Federal Project Director Bill McMillan said. “Now that we can ensure the safety of each drum, they are ready for transport to the Transuranic Waste Processing Center for processing and subsequent shipment to a permanent disposal facility away from Oak Ridge.” [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…]

For the first time in 30 years, spent nuclear fuel from the High Flux Isotope Reactor at Oak Ridge National Laboratory has been dissolved at the Savannah River Site in South Carolina.

The work is important because it is expected to allow the reactor, known as HFIR, to continue its mission, according to the U.S. Department of Energy Office of Environmental Management.

HFIR, which uses highly enriched uranium, is one of the world’s most powerful nuclear research reactor facilities. It’s the highest flux reactor-based source of neutrons for research in the United States. Flux refers to the rate of flow of fluids, particles, or energy. In HFIR’s case, the flux is measured in neutrons per square centimeter per second. HFIR is used for neutron scattering and isotope production, among other missions.

ORNL will reach its maximum capacity for storing HFIR fuel in fiscal year 2020, the DOE Office of Environmental Management, or EM, said in an “EM Update” electronic newsletter on Tuesday. [Read more…]
