JUNE 2018

The TOP500 celebrates its 25th anniversary with a major shakeup at the top of the list. For the first time since November 2012, the US claims the most powerful supercomputer in the world, leading a significant turnover in which four of the five top systems were either new or substantially upgraded.

Summit, an IBM-built supercomputer now running at the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL), captured the number one spot with a performance of 122.3 petaflops on High Performance Linpack (HPL), the benchmark used to rank the TOP500 list. Summit has 4,356 nodes, each one equipped with two 22-core Power9 CPUs, and six NVIDIA Tesla V100 GPUs. The nodes are linked together with a Mellanox dual-rail EDR InfiniBand network.

Sunway TaihuLight, a system developed by China’s National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi, drops to number two after leading the list for the past two years. Its HPL mark of 93 petaflops has remained unchanged since it came online in June 2016.

Sierra, a new system at the DOE’s Lawrence Livermore National Laboratory took the number three spot, delivering 71.6 petaflops on HPL. Built by IBM, Sierra’s architecture is quite similar to that of Summit, with each of its 4,320 nodes powered by two Power9 CPUs plus four NVIDIA Tesla V100 GPUs and using the same Mellanox EDR InfiniBand as the system interconnect.

Tianhe-2A, also known as Milky Way-2A, moved down two notches into the number four spot, despite receiving a major upgrade that replaced its five-year-old Xeon Phi accelerators with custom-built Matrix-2000 coprocessors. The new hardware increased the system’s HPL performance from 33.9 petaflops to 61.4 petaflops, while bumping up its power consumption by less than four percent. Tianhe-2A was developed by China’s National University of Defense Technology (NUDT) and is installed at the National Supercomputer Center in Guangzhou, China.

The new AI Bridging Cloud Infrastructure (ABCI) is the fifth-ranked system on the list, with an HPL mark of 19.9 petaflops. The Fujitsu-built supercomputer is powered by 20-core Xeon Gold processors along with NVIDIA Tesla V100 GPUs. It’s installed in Japan at the National Institute of Advanced Industrial Science and Technology (AIST).

Piz Daint (19.6 petaflops), Titan (17.6 petaflops), Sequoia (17.2 petaflops), Trinity (14.1 petaflops), and Cori (14.0 petaflops) move down to the number six through 10 spots, respectively.

中国蝉联第8届TOP500全球超算冠军

The 48th edition of the TOP500 list saw China and United States pacing each other for supercomputing supremacy. Both nations now claim 171 systems apiece in the latest rankings, accounting for two-thirds of the list. However, China has maintained its dominance at the top of the list with the same number 1 and 2 systems from six months ago: Sunway TaihuLight, at 93 petaflops, and Tianhe-2, at 34 petaflops. This latest edition of the TOP500 was announced Monday, November 14, at the SC16 conference in Salt Lake City, Utah.

After US and China, Germany claims the most systems with 32, followed by Japan with 27, France with 20, and the UK with 17. A year ago the US was the clear leader with 200 systems, while China had 108, Japan had 37, Germany had 33, and both France and the UK had 18.

In addition to matching each other in system count in the latest rankings, China and the US are running neck and neck in aggregate Linpack performance. The US holds the narrowest of leads, with 33.9 percent of the total; China is second with 33.3 percent. The total performance of all 500 computers on the list is now 672 petaflops, a 60 percent increase from a year ago.

The top of the list did receive a mild shakeup with two new systems in the top ten. The Cori supercomputer, a Cray XC40 system installed at Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC), slipped into the number 5 slot with a Linpack rating of 14.0 petaflops. Right behind it at number 6 is the new Oakforest-PACS supercomputer, a Fujitsu PRIMERGY CX1640 M1 cluster, which recorded a Linpack mark of 13.6 petaflops. Oakforest-PACS is up and running at Japan’s Joint Center for Advanced High Performance Computing (JCAHPC). Both machines owe their computing prowess to the Intel “Knights Landing” Xeon Phi 7250, a 68-core processor that delivers 3 peak teraflops of performance.

The addition of Cori and Oakforest-PACS pushed every system below them a couple of notches down, with the exception of Piz Daint, a Cray supercomputer installed at the Swiss National Supercomputing Centre (CSCS). It maintained its spot at number 8 as a result of a massive 3.5 petaflop upgrade, courtesy of newly installed NVIDIA P100 Tesla GPUs.
Piz Daint also has the honor of being the second most energy-efficient supercomputer in the TOP500, with a rating of 7.45 gigaflops/watt. It is topped by NVIDIA’s in-house DGX SATURNV system, the only other system on the list equipped with the new P100 GPUs. It is a 3.3-petaflop cluster of DGX-1 servers that delivers 9.46 gigaflops/watt. To offer some perspective here, the nominal goal for the first exascale systems is 50 gigaflops/watt.
