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.

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.

Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

The Y-12 National Security Complex in Oak Ridge manufactured the uranium reactor core for a federal experiment that tested whether a nuclear energy source could provide power for space exploration.

“The full-power run showed that it may be feasible for NASA to use small fission reactors for deep space exploration and manned missions to the moon and Mars,” the National Nuclear Security Administration said in May.

The NNSA, which is part of the U.S. Department of Energy, worked with NASA (the National Aeronautics and Space Administration) on the project. It’s nicknamed KRUSTY, an acronym for Kilowatt Reactor Using Stirling Technology.

“In a joint venture with NASA last year, NNSA completed final design, fabrication, and full-power testing of a nuclear criticality experiment that can be used for a manned lunar or Mars space mission,” NNSA Administrator Lisa Gordon-Hagerty said in a post published on Twitter on Friday.

The uranium reactor core from Y-12 was delivered to the National Criticality Experiments Research Center at the Nevada National Security Site in the fall of 2017. [Read more…]

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…]
