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 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.

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…]
