Bronson Messer, director of science at the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory, will speak virtually to Friends of ORNL on Tuesday, Mar. 8, at 12 noon on “Computational Science at the Dawn of the Exascale Era.”
He will describe important scientific findings that resulted from modeling and simulations at the Summit supercomputer at ORNL, including work relevant to combating the COVID-19 disease.
He will also mention research projects planned for the Frontier supercomputer under construction at ORNL. This “exascale” machine will be capable of a quintillion (billion times a billion) calculations per second, which is 50 times faster than the most powerful supercomputers in use today and 1,000 times faster than the supercomputers that came online 14 years ago.
The talk is open to the public. To view the virtual lecture, click on the talk title on the homepage of the www.fornl.org website and click on the Zoom link near the top of the page describing the lecture. Here is Messer’s summary of what he will talk about.
“Regardless of our increasing reliance on and familiarity with computing power in our everyday lives, modern supercomputers are unique scientific instruments, more akin to the Large Hadron Collider or the James Webb Space Telescope than to our laptop computers and cellphones. Unlike those large devices, however, supercomputers are also among the most versatile of scientific instruments, as they push back frontiers in physics, biology, climate and many other fields.
“I will describe how the Summit supercomputer is used in modern scientific research and mention some recent discoveries, including work on the COVID-19 pandemic. I will also provide a glance ahead to the first science we hope will be accomplished with the under-construction Frontier machine, which is planned to be the nation’s first exascale supercomputer – that is, a machine capable of one quintillion floating-point operations per second.”
A computational astrophysicist, Messer is also a Distinguished Scientist and joint faculty associate professor in the Department of Physics and Astronomy at the University of Tennessee. Prior to joining ORNL, he was a research associate in the Department of Astronomy and Astrophysics at the University of Chicago, where he was deputy group leader for astrophysics in the ASC Center for Astrophysical Thermonuclear Flashes.
He is a member of the American Astronomical Society and recently served on the American Physical Society’s Committee on Informing the Public (2018-2020). In 2020, he was awarded the Department of Energy Secretary’s Honor Award for his part in enabling the COVID-19 High Performance Computing Consortium. Messer holds undergraduate and graduate degrees from the University of Tennessee, where he earned his Ph.D. in physics in 2000.
His primary research interests are related to the explosion mechanisms and phenomenology of supernovae, especially neutrino transport and signatures, dense matter physics and the details of turbulent nuclear combustion. He also has worked on the application of machine learning algorithms to the analysis of galaxy merger simulations and on performance modeling and prediction for high-performance computing architectures.

The Summit supercomputer at Oak Ridge National Laboratory remained the fastest system in the United States and the second-most powerful in the world in the biannual TOP500 list released Monday.

Fugaku in Kobe, Japan, remained No. 1, where it has been since June 2020. The 442-petaflop system has been at the top of the list four consecutive times.

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 the second and third most powerful supercomputers, Summit at number two and Sierra at Lawrence Livermore National Laboratory in California at number three.

Fugaku is installed at the Riken Center for Computational Science. It was co-developed by Riken and Fujitsu, and it has 7,630,848 cores. It is based on Fujitsu’s custom ARM A64FX processor, TOP500 said. Fugaku uses a Fujitsu interconnect known as Tofu D to transfer data between nodes.

TOP500 said Fugaku’s 442-petaflop performance on a benchmark test makes it three times as powerful as Summit, which has 2,414,592 cores. 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.

The Summit supercomputer at Oak Ridge National Laboratory has been used to identify drug compounds, including medications and natural compounds, that could help fight coronavirus, although more study is needed.

“The researchers used Summit, the world’s most powerful and smartest supercomputer, to identify 77 small-molecule drug compounds that might warrant further study in the fight against the SARS-CoV-2 coronavirus, which is responsible for the COVID-19 disease outbreak,” ORNL said in a response to questions Wednesday.

The researchers performed simulations on Summit of more than 8,000 compounds to screen for those that are most likely to bind to the main “spike” protein of the coronavirus, rendering it unable to infect host cells. They ranked compounds of interest that could have value in experimental studies of the virus. They published their results on “ChemRxiv.”

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 National Nuclear Security Administration has signed a $600 million contract with Cray Inc. to build the first exascale supercomputer for the NNSA at Lawrence Livermore National Laboratory in California.

It is one of three exascale systems to be built at U.S. Department of Energy or NNSA laboratories. The other two exascale machines will be at DOE laboratories: Aurora at Argonne National Laboratory near Chicago and Frontier at Oak Ridge National Laboratory.

ORNL currently has the most powerful supercomputer in the world, Summit, and LLNL has the second-fastest, Sierra. They are both petaflop systems. Summit is capable of 200 petaflops, or 200,000 trillion calculations per second.

All three of the new exascale supercomputers will be built by Cray using their Shasta architecture, Slingshot interconnect, and new system software platform, the NNSA said in a press release Tuesday.

An exascale computer will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 1018, calculations per second. That’s a billion billion calculations per second.

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.

The U.S. Department of Energy on Tuesday announced a contract with Cray Inc. to build the Frontier supercomputer at Oak Ridge National Laboratory. It is expected to be the world’s most powerful supercomputer when it debuts in 2021.

The contract with Cray is valued at more than $600 million for the system and technology development, a press release said.

Energy Secretary Rick Perry was at ORNL on Tuesday morning to make the announcement.

“This is a big deal,” Perry said. “Frontier’s record-breaking performance will ensure our country’s ability to lead the world in science that improves the lives and economic prosperity of all Americans and the entire world. Frontier will accelerate innovation in AI (artificial intelligence) by giving American researchers world-class data and computing resources to ensure the next great inventions are made in the United States.”

Besides the supercomputing announcement on Tuesday, Perry also delivered the keynote speech at InnovationXLab: Advanced Manufacturing Summit at ORNL.

Frontier is expected to perform at greater than 1.5 exaflops. It will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 1018, calculations per second, the press release said. That’s a billion billion calculations per second.

Oak Ridge Today has previously reported that Frontier would be built at ORNL. But the contract with Cray and its value and the specific performance estimate of more than 1.5 exaflops are all new announcements. The contract award includes technology development funding, a center of excellence, several early-delivery systems, the main Frontier system, and multi-year systems support. The Frontier system is expected to be delivered in 2021, and acceptance is expected in 2022.

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 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…]
