The World’s 10 Fastest Supercomputers – in Pictures

US has regained the top spot on Top500, a biannually updated list of the world’s fastest supercomputers • There hasn’t been an American system at the top of the list since 2012 • China’s Sunway TaihuLight topped the list for the two previous years • China’s Tiahne 2, or Milky Way-2, system was number-one for three years before that • With 202 systems on the list, China still leads as the country with more supercomputers on Top500 than any other

As expected, US has regained the top spot on the biannually updated list of the world’s fastest supercomputers, unseating China as the global supercomputing leader. One Chinese system topped the list for the last two years, and another topped it for the preceding three years.

The US Department of Energy’s Summit supercomputer by IBM (more on the new Summit system here) is number-one on the June 2018 edition of the Top500 list published Monday. Sunway TaihuLight, the former Top500 champion running at the National Supercomputing Center in Wuxi, China, slid into second place.

This is the first time US can claim the world’s most powerful supercomputer since 2012. Another Chinese system, Tianhe-2 (Milky Way-2), topped the list for three consecutive years before being unseated by the TaihuLight.

The latest edition of the list puts Tianhe-2 in the number-four spot, just behind Sierra, a new system installed at the DOE’s Lawrence Livermore National Laboratory, which is now the world’s third-fastest non-distributed computing system.

Another new system, called AI Bridging Cloud Infrastructure, came in fifth. Built by Fujitsu, it’s running at Japan’s National Institute of Advanced Industrial Science and Technology.

While US is once again at the top of Top500, China still has more systems on the list than any other country. There are 202 Chinese supercomputers on the list and 124 American ones.

US is number-two by system count, followed by Japan (36), UK (22), Germany (21), and France (18).

The US also won by total performance. American supercomputers contributed 38.2 percent of aggregate installed performance of all 500 systems on the list. China contributed 29.1 percent.

Now, let's take a closer look at 10 of the world’s fastest supercomputers as of June 2018 (all data courtesy of Top500.org):
