At 200 petaflops, the U.S. once again owns the world's fastest supercomputer

Share

Yesterday (June 8), the US Department of Energy's Oak Ridge National Laboratory announced the top speeds of its Summit supercomputing machine, which almost laps the previous record-holder, China's Sunway TaihuLight. Summit is made up of more than 9,000 22-core IBM Power9 processors and over 27,000 NVIDIA Tesla V100 GPUs.

Official, Linpack benchmarks have not yet been disclosed for Summit, but its 200-plus petaflop peak, touted by ORNL, "will surely be enough to outrun the 93-petaflop Linpack mark of the current TOP500 champ, China's Sunway TaihuLight", Top500.org says.

The Massachusetts Institute of Technology's Technology Review reported the computer is 60 percent faster than the supercomputer that was previously the world's most powerful.

Summit is a scientific supercomputer to be used in researches in the field of energy, new materials, artificial intelligence, astrophysics, biomedicine, etc., paving the way for new discoveries that until now were impossible.

The supercomputer has more than 10 petabytes of memory, the lab said. It's twice as fast as the record now held by China's Sunway TaihuLight, which is listed at 93.01 petaflops on last November's authoritative TOP500 list.

"It can do, in fractions of a second, what it would take millions of computers to do otherwise", says John Kelly, a senior vice president with IBM, which built the machine.

"Summit's unprecedented power will enable scientists to tackle some of the most complex challenges facing our nation and the world today", added Congressman Fleischmann.

A water-cooled IBM system, Summit is presumed to have bumped China from the top spot, at least among open-science systems or supercomputers that aren't classified. To put that in human terms, approximately 6.3 billion people would all have to make a calculation at the same time to match what Summit can do in just one second.

Supercomputers have myriad uses, many of which are essential to national security and the general welfare of the public.

U.S. launches world's most powerful Summit supercomputer! "Summit is a magnificent scientific instrument that will attract the world's great scientists.Summit is a milestone in a global race". ORNL researchers have also figured out how to harness the power and intelligence of Summit's state-of-art architecture to successfully run the world's first exascale scientific calculation, or exaops, as DOE's fleet of proposed exascale computing systems come online in the next five years. Researchers will use Summit's power to probe other disease markers, such as for Alzheimer's, heart disease and addiction.
