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…]

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…]

An appropriations bill approved by a Senate subcommittee on Tuesday rejects the Trump administration’s proposal to cut $919 million in funding from the U.S. Department of Energy’s Office of Science in the fiscal year that starts October 1.

Instead of cutting, the Senate bill would actually increase funding for the Office of Science, boosting it to $5.55 billion in fiscal year 2018. That would be again a record funding level in a regular appropriations bill, according to U.S. Senator Lamar Alexander, a Tennessee Republican who often advocates for the federal sites in Oak Ridge and chairs the Senate subcommittee.

Like the Senate this week, the House Appropriations Committee last week also rejected President Donald Trump’s request to cut DOE’s Office of Science.

Unlike the Senate bill, though, the House bill would keep funding flat at $5.39 billion, the same as in the current fiscal year. That level of funding was also a record in a regular appropriations bill, Alexander said in May.

The Office of Science is the nation’s largest supporter of research in the physical sciences.

The president’s budget request, submitted to Congress on May 23, would cut Office of Science funding by about 17 percent, dropping it to $4.47 billion.

Keeping Office of Science funding flat, or even increasing it, could be important to several of the federal sites in Oak Ridge. Oak Ridge National Laboratory is an Office of Science lab, and the Office of Scientific and Technical Information, or OSTI, is an Office of Science unit. [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…]

Climate and energy scientists at Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise.

“For the first time, we were able to apply data at a high enough resolution to be relevant,” said ORNL’s Melissa Allen, co-author of “Impacts of Climate Change on Sub-regional Electricity Demand and Distribution in the Southern United States,” published in Nature Energy.

Allen and her team developed new algorithms that combine ORNL’s unique infrastructure and population datasets with high-resolution climate simulations run on the lab’s Titan supercomputer. The integrated approach identifies substations at the neighborhood level and determines their ability to handle additional demand based on predicted changes in climate and population.

The new, high-resolution capability can explore the interconnections in complex systems such as critical infrastructure and weather and determine potential pathways to adapt to future global change, a press release said. [Read more…]

Oak Ridge National Laboratory and its Titan supercomputer are helping the U.S. Department of Energy fight cancer through a national initiative called Cancer Moonshot.

U.S. Energy Secretary Ernest Moniz wrote about the use of DOE supercomputers to fight cancer in an article posted on Medium.com on Friday.

“Cancer is a worldwide public health problem, and the second-leading cause of death in the United States,” Moniz said. “Although cancer mortality has declined in recent years, there is no one who hasn’t been touched by cancer personally. So when President Obama announced that Vice President Biden would lead the Cancer Moonshot during his State of the Union address and asked for all hands on deck, I was eager to join the Cancer Moonshot Task Force and lend the support of the Department of Energy and our 17 national laboratories.”

As part of the initiative, the U.S. Department of Energy is launching three pilot projects in partnership with the National Cancer Institute, ORNL spokesperson Morgan McCorkle said. The projects will bring together nearly 100 cancer researchers, care providers, computer scientists, and engineers to apply the nation’s most advanced supercomputing capabilities to analyze data from preclinical models in cancer, cancer surveillance data, and molecular interaction data for RAS genes, McCorkle said. (About one third of all human cancers, including a high percentage of pancreatic, lung, and colorectal cancers, are driven by mutations in RAS genes, according to the National Cancer Institute.)

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.

China maintained its number one ranking in the latest edition of the TOP500 list of the world’s top supercomputers, but with a new system built entirely using processors designed and made in China.

China now has the top two supercomputers on the semiannual TOP500 list, and Titan at Oak Ridge National Laboratory has dropped from number two to number three.

The new Chinese supercomputer, Sunway TaihuLight, is capable of 93 petaflops, or quadrillions of calculations per second, a press release said.

It displaced Tianhe-2, an Intel-based Chinese supercomputer that had claimed the number one spot on the past six TOP500 lists. Tianhe-2 achieved a speed of 33.86 petaflops, or more than 33,000 trillion calculations per second, in a test known as the LINPACK benchmark.

Titan, a Cray XK7 system installed at ORNL, a U.S. Department of Energy laboratory, achieved 17.59 petaflops.

Titan was the top system for a short time. It was number one in November 2012, but it was bumped to number two behind Tianhe-2 in June 2013. This is the first time it has been number three.

The latest list marks the first time since the start of the TOP500 that the United States is not home to the largest number of systems. With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the U.S. is second with 165. China also leads the performance category, thanks to the number one and number two systems, the press release said. [Read more…]
