Summit at ORNL remains No. 2 in world

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.

Japanese supercomputer displaces ORNL’s Summit as world’s most powerful

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.

DOE still has top two supercomputers, including Summit at ORNL

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).

DOE: New $600 million supercomputer at ORNL will be world’s most powerful

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.
