Top 5 Supercomputers from TOP 500 list all sporting petaflops in abundance

The TOP 500 project has released a list of500 supercomputers, but this time, all 500 systems deliver a petaflop or moreon the High Performance Linpack (HPL) benchmark, with the entry level to thelist now at 1.022 petaflops.

The benchmark the project decided on was Linpack, which means that systemsare ranked only by their ability to solve a set of linear equations, A x = b,using a dense random matrix A.

The top of the list remains largely unchanged, according to TOP500, but hasseen the addition of two new entries in the top 10, one of which was anexisting system that was upgraded with additional capacity.

Here is the top 5!

Summit and Sierra

Two IBM-built supercomputers, Summit and Sierra, installed at the Departmentof Energy?s Oak Ridge National Laboratory in Tennessee and Lawrence LivermoreNational Laboratory in California, respectively, retain the first two positionson the list.

Both derive their computational power from Power 9 CPUs and NVIDIA V100GPUs. The Summit system slightly improved its HPL result from six months ago,delivering 148.6 petaflops, while the number two Sierra system remainsunchanged at 94.6 petaflops.

The Sunway TaihuLight

The Sunway TaihuLight, a system developed by China?s National ResearchCentre of Parallel Computer Engineering & Technology (NRCPC) and installedat the National SupercomputingCentre in Wuxi, China, holds the number three position with 93.0petaflops. It?s powered by more than 10 million SW26010 processor cores.


At number four is the Tianhe-2A (Milky Way-2A) supercomputer, developed byChina?s National University of Defense Technology (NUDT) and deployed at theNational Supercomputer Centre in Guangzhou, China.

It used a combination of Intel Xeon and Matrix-2000 processors to achieve anHPL result of 61.4 petaflops.


Frontera, the only new supercomputer in the top 10, attained its number fiveranking by delivering 23.5 petaflops on HPL.

The Dell C6420 system, powered by Intel Xeon Platinum 8280 processors, isinstalled at the Texas Advanced Computing Centre of the University of Texas.

Others on the list included, Piz Daint, Trinity, a Cray XC40 system operatedby Los Alamos National Laboratory and Sandia National Laboratories improves itsperformance to 20.2 petaflops, and the AI Bridging Cloud Infrastructure (ABCI)which is installed in Japan at the National Institute of Advanced IndustrialScience and Technology (AIST).

China claims the most TOP500 systems, with 219, followed by the UnitedStates, with 116. Japan is in third place with 29 systems, followed by France,with 19, the United Kingdom, with 18, and Germany with 14.
