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…]

Arthur “Buddy” Bland, program director of the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory, has received the Secretary’s Appreciation Award for his nearly four decades of achievements in providing high-performance computing resources for science, a press release said.

Bland was cited by U.S. Energy Secretary Rick Perry for his work “in recognition of nearly 40 years of leadership in delivering high-performance computing resources to address the nation’s science and engineering challenges across a wide array of disciplines and for critical contributions to the success of the Oak Ridge Leadership Computing Facility and sustained U.S. leadership in high-performance computing and computational science.”

Bland led the project to deliver the Summit supercomputer, launched June 8 at ORNL as “the world’s most powerful and smartest supercomputer” with a peak performance capability of 200 petaflops, or 200,000 trillion calculations per second. Summit was listed number one in the TOP500 list released on Monday. [Read more…]

Record funding in federal budget could help Oak Ridge, senator says

The federal budget expected to be complete by mid-December should have record funding, and the money could help Oak Ridge in areas ranging from mercury and Cold War cleanup to scientific research and the proposed Uranium Processing Facility, U.S. Senator Lamar Alexander said Friday.

The Oak Ridge area now receives about $3 billion per year in federal funding, and the level will be increased although he doesn’t have a number yet, said Alexander, a Tennessee Republican.

Alexander held a brief press conference at the Oak Ridge Municipal Building on Friday.

He said the U.S. Department of Energy’s Office of Science, which provided $1.4 billion to Oak Ridge National Laboratory this year, will have a record level of funding. [Read more…]

Alexander: Bill raises Office of Science funding to highest-ever, includes UPF, supercomputing, cleanup funding

A bill approved by a U.S. Senate subcommittee on Tuesday would give $5.144 billion to the federal agency that oversees work at Oak Ridge National Laboratory. It’s the highest level of funding ever for the U.S. Department of Energy’s Office of Science, which oversees 10 national labs, including ORNL, federal officials said.

The bill would also provide $430 million for the proposed Uranium Processing Facility at the Y-12 National Security Complex, which will “continue to keep this project on time and on budget,” according to a press release from the office of U.S. Senator Lamar Alexander, a Tennessee Republican.

Alexander’s office also said the legislation would provide funding for:

  • a new mercury treatment plant in Oak Ridge,
  • cleanup of nuclear facilities that are no longer in service,
  • nuclear infrastructure at Oak Ridge National Laboratory, and
  • advanced computing, which supports the new Summit supercomputer at Oak Ridge National Laboratory.

The bill was unanimously approved on a voice vote by the Appropriations Subcommittee on Energy and Water Development on Tuesday afternoon. Alexander is chair of that subcommittee, and he said the approval shows that there is bipartisan support for energy research, waterways, and national security. [Read more…]
