For first time since 2012, US has top supercomputer in world

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…]

Once the world’s most powerful supercomputer, Titan at Oak Ridge National Laboratory dropped to number four on a list of the world’s most powerful supercomputers released Monday.

Titan, a Cray XK7 system, was bumped from the number three spot by the upgraded Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre.

China continues to have the world’s two most powerful supercomputers.

The TOP50 List of the world’s most powerful supercomputers is based on a benchmark test known as Linpack. The list is released twice each year, once in June and again in November. The 49th edition of the TOP500 List was released Monday in conjunction with the opening session of the ISC High Performance conference, which is taking place this week in Frankfurt, Germany.
