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…]

The Oak Ridge Breakfast Rotary Club welcomed Thomas Zacharia, director of the Oak Ridge National Laboratory to its August 9 breakfast meeting. Zacharia became director of ORNL on July 1, 2017, after a long and successful career with ORNL beginning in 1987 as a postdoctoral researcher and culminating in his recent appointment as director.

His professional career at ORNL spans many fields with a special focus in materials research and computational sciences. In his comments to the club, he outlined his long-term expectations for ORNL and its critical role in supporting U.S. Department of Energy missions to advance science and technology in such areas as high-performance computing, advanced materials, nuclear power, and national security.

In addition, Thomas stated he expects ORNL will continue to expand its role in transferring ORNL technologies to industry in the local area and across the nation. ORNL scientific discoveries are expected to continue to help make our economy more competitive in world markets. [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…]

Once the world’s most powerful supercomputer, Titan at Oak Ridge National Laboratory dropped to number four on a list of the world’s most powerful supercomputers released Monday.

Titan, a Cray XK7 system, was bumped from the number three spot by the upgraded Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre.

China continues to have the world’s two most powerful supercomputers.

The TOP50 List of the world’s most powerful supercomputers is based on a benchmark test known as Linpack. The list is released twice each year, once in June and again in November. The 49th edition of the TOP500 List was released Monday in conjunction with the opening session of the ISC High Performance conference, which is taking place this week in Frankfurt, Germany.

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…]

New 200-petaflop supercomputer to succeed Titan at ORNL

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 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…]

Oak Ridge National Laboratory will have the world’s fastest next-generation supercomputer, U.S. Senator Lamar Alexander announced at a Friday morning press conference with U.S. Energy Secretary Ernest Moniz.

Alexander, a Tennessee Republican, said the new computer will provide five times the performance of Titan, the current system, and support advanced scientific and materials research to improve economic and national security.

The “next-generation hybrid supercomputer” will be called Summit, and it will be delivered in 2017, the senator said.

“Once again the world’s fastest computer will be in the United States, and once again it will be at Oak Ridge,” Alexander said. “Supercomputing has helped Tennessee become a center for advanced manufacturing with the arrival of new companies, including several in the auto industry, creating thousands of good-paying jobs. Tennessee can continue to thrive and create many more good jobs with the use of this new supercomputer.” [Read more…]
