The Summit supercomputer at Oak Ridge National Laboratory remains the fastest supercomputer in the United States and the second most powerful in the world.

Summit, an IBM system, was the world’s most powerful supercomputer from June 2018 to November 2019, when the U.S. Department of Energy had the two fastest systems in the world.

DOE still has two of the three fastest supercomputers, Summit at ORNL and Sierra at Lawrence Livermore National Laboratory in Livermore, California. And it has three of the top five systems in the world. DOE has a new supercomputer, Perlmutter, ranked at number five. It’s at the National Energy Research Scientific Computing Center at the Lawrence Berkeley National Laboratory, in Berkeley, California. Perlmutter was the only new system in the top 10 in the semiannual TOP500 list released Monday.

Summit was bumped from the top spot on the TOP500 list by a Japanese supercomputer, Fugaku, in June 2020.

Fugaku, which is in Kobe, Japan, remained in the top spot on the TOP500 list released in November and again on the list released Monday. The TOP500 list uses a benchmark test to rank the world’s most powerful supercomputers.

A Japanese supercomputer has displaced the Summit supercomputer at Oak Ridge National Laboratory as the world’s most powerful and bumped other U.S. and Chinese machines down one spot on a semiannual list of the fastest systems.

Summit had been ranked the world’s most powerful supercomputer on the semiannual TOP500 list since June 2018. It was bumped to number two when the new TOP500 list was released Monday.

The new top system is installed in Kobe, Japan, and it is named Fugaku. In a high-performance test, it performed at 415.5 petaflops. A petaflop is a quadrillion floating-point operations per second.

Fugaku’s performance was 2.8 times better than Summit’s, according to TOP500. Summit delivered 148.8 petaflops on the high-performance test.

Tennessee reported 1,188 new COVID-19 cases on Friday, a new daily high, and the state passed 500 confirmed deaths on Saturday, according to the Tennessee Department of Health.

The new high in daily new cases occurred in the same week that the state reported what are now its third- and sixth-highest totals of new cases in one day: 885 on Sunday, June 14, and 726 on Monday, June 15.

Of the 1,188 new cases reported Friday, the state said 1,181 were new confirmed cases and seven were new probable cases.

The previous daily high was 1,156 on May 1. That was reported after a large number of new cases was diagnosed at Turner Trousdale Correctional Center, according to Nashville investigative reporter Phil Williams.

It’s not clear why there was a new high on Friday. There was a large number of new tests reported, 15,176. But the rate of positive results, 7.8 percent (comparing total new cases to total new tests), was in the range of the rate for the rest of the week, when the positive rate ranged between 4.9 percent and 8.8 percent.

The U.S. Department of Energy still has the two most powerful supercomputers in the world, including Summit at Oak Ridge National Laboratory, according to a semiannual list released Monday.

It’s the fourth time in the past two years that Summit, an IBM-built supercomputer, has been number one on the TOP500 list of of the world’s most powerful supercomputers.

The United States displaced China at the top of the list last year, in June. Two years ago, in November 2017, China had the top two systems in the world.

Summit debuted at number one in June 2018. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. Summit retained the top spot in November 2018 and again in June 2019.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, climbed to number two from number three in November 2018. It remained at number two on the June list and again on the list released Monday, meaning it’s been number two on three versions of the list in the past two years.

Summit and Sierra are both IBM-built supercomputers that use Power9 central processing units (CPUs) and NVIDIA Tesla V100 graphics processing units (GPUs).

The Summit supercomputer at Oak Ridge National Laboratory remains the world’s most powerful, according to a ranking list released Monday.

It’s the third time that Summit, a IBM-built supercomputer, has been number one on the semiannual TOP500 list of of the world’s most powerful supercomputers. Summit debuted at number one in June 2018. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. Summit retained the top spot in November.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, remained at number two on the list released Monday, after climbing there from number three in November. The United States continues to have the top two systems in the world, a position that China held a year and a half ago.

Officials celebrated the launch of Summit in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8, 2018. The supercomputer is capable of 200 petaflops, or 200,000 trillion calculations per second. That makes it about eight times more powerful than Titan, its predecessor, which was once the world’s fastest.

Summit delivered a record 148.6 petaflops on a benchmark test called High Performance Linpack, or HPL, a TOP500 press release said Monday. That was a slight improvement from six months ago, when Summit scored 143.5 petaflops. Summit debuted at 122.3 petaflops in June 2018.

Almost 700 kilograms of highly enriched uranium has been moved from the United Kingdom to the United States, and the material is being securely stored at the Y-12 National Security Complex in Oak Ridge for now, federal officials said.

The National Nuclear Security Administration said this month that the highly enriched uranium, or HEU, will be down-blended later into low enriched uranium for use as nuclear reactor fuel.

“The material was returned to Y-12 for secure storage awaiting future disposition,” the NNSA said in a statement provided Friday by Steven Wyatt of the NNSA Production Office in Oak Ridge.

Wyatt said Y-12 supported the removal effort, which was announced by the NNSA on May 3, through technical oversight and guidance of the processing and packaging of material.

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 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…]

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…]
