The latest, 53rd, edition of Top500 marks the first time all 500 systems on the list are capable of at least 1 petaflop, or one quadrillion floating point operations per second. The slowest system on the list, the Internet Company N D2 system built by Lenovo for China’s Network Company, clocked in at 1.022 petaflops, making Top500 a “petaflop club for supercomputers,” according to Top500.org.
Ranking at the top of the list hasn’t changed much since the last edition, with Summit and Sierra, IBM systems at the Department of Energy’s Oak Ridge National Laboratory in Tennessee and Lawrence Livermore National Laboratory in California, respectively, still in the first and second positions.
In fact, Summit, the world’s fastest supercomputer, improved its performance results from six months ago, going from 143.5 petaflops to 148.6 petaflops. Sierra’s performance benchmark hasn’t changed, remaining at 94.6 petaflops.
Both systems run Power 9 CPUs in combination with Nvidia V100 GPUs.
The Sunway TaihuLight at the National Supercomputing Center in Wuxi, China, remained in the third position with 93.0 petaflops, while Tianhe-2A, also known as Milky Way-2A, held on to the fourth place. The former is powered by Chinese Sunway chips and the latter by Intel Xeon processors.
The fifth supercomputer on the list is 23.5-petaflops Frontera, the only new system in the top 10. It’s an Intel-powered Dell system installed at the University of Texas’s Texas Advanced Computing Center.
Here are the details of the world’s 10 fastest supercomputers, according to the June 2019 Top500 list (full list here). All data courtesy of Top500.org:
