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.

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.

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.”

Oak Ridge National Laboratory is involved in early research and using the Summit supercomputer to better understand components of the new coronavirus, which was first reported in China but is now being reported in a growing number of countries across the world, including the United States.

The early research at ORNL uses computational modeling and data analysis techniques on Summit, the world’s most powerful supercomputer. Results are not published yet, ORNL said Friday afternoon.

Oak Ridge Today has requested more information about the lab’s research, including who the work is for and what parts of the virus are being researched, but that information wasn’t immediately available.

The Centers for Disease Control and Prevention said it is closely monitoring the outbreak of respiratory illnesses caused by the new coronavirus, and there are ongoing investigations to learn more.

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 Titan supercomputer at Oak Ridge National Laboratory debuted as the fastest computer in the world in 2012, and it remained in the top 10 for seven years, providing billions of core hours of total computing time to researchers from around the world. The system will be decommissioned on Aug. 1, 2019, and its data center space will be retrofitted for a new supercomputer, Frontier. (Photo by ORNL)

A supercomputer that was once the world’s fastest will be retired at Oak Ridge National Laboratory on August 1.

The supercomputer is a Cray XK7 machine called Titan. It is operated by the Oak Ridge Leadership Computing Facility. It’s a petaflop system capable of performing up to 27 quadrillion calculations per second.

Titan was the world’s fastest supercomputer in November 2012, but it was bumped to number two by Tianhe-2, a Chinese supercomputer in June 2013. Still, Titan continued to rank as one of the world’s top 10 fastest supercomputers from its debut at number one in 2012 until this June, when it dropped to number 12.

In June, ORNL said Titan, which has been operating for seven years, will be decommissioned on August 1 and disassembled for recycling. Titan will be removed to make room for a new, much more powerful supercomputer, Frontier. That will be an exascale system capable of 1.5 exaflops, or 1.5 quintillion calculations per second (a billion billion calculations per second). Frontier will be a $600 million Cray computer that is expected to be the world’s most powerful when it debuts in 2021.

The United States has the two fastest supercomputers in the world, and they are both at U.S. Department of Energy laboratories.

DOE and its National Nuclear Security Administration have two other supercomputers in the top 10.

“DOE’s national labs have some of the brightest minds in the world, which have made America a worldwide leader in high-performance computing hardware, software, and applications,” U.S. Secretary of Energy Rick Perry said in a press release Monday. â€œWe are well-positioned to maintain this leadership as we enter the era of exascale computing, which holds enormous promise for our country and will transform our leadership in science, our economy, and our nation’s security.”

As reported by Oak Ridge Today on Monday, the Summit supercomputer at Oak Ridge National Laboratory is still the fastest supercomputer in the world.

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.

U.S. Energy Secretary Rick Perry on Tuesday dismissed a news story that he plans to leave the U.S. Department of Energy, and he suggested the story was the product of a “rumor factory.”

Perry was asked about the Bloomberg News story during a brief question-and-answer session with reporters at Oak Ridge National Laboratory on Tuesday morning, after DOE and Cray announced that Frontier, an exascale supercomputer to be built at the lab, is expected to be the world’s most powerful when it debuts in 2021.

Perry said there have been previous reports that he planned to move to the Veterans Administration, Department of Homeland Security, and Department of Defense.

“I guess the rumor factory ran out of places for me to move inside the Cabinet,” Perry said.
