The World's Fastest Supercomputers Hit Higher Speeds Than Ever With Linux

'In the latest Top 500 supercomputer ratings, the average speed of
these Linux-powered racers is now an astonishing 1.14 petaflops. The
fastest of the fast machines haven't changed since the June 2019 Top
500 supercomputer list. Leading the way is Oak Ridge National
Laboratory's Summit system, which holds top honors with an HPL result
of 148.6 petaflops. This is an IBM-built supercomputer using Power9
CPUs and NVIDIA Tesla V100 GPUs. In a rather distant second place is
another IBM machine: Lawrence Livermore National Laboratory's Sierra
system. It uses the same chips, but it "only" hit a speed of 94.6
petaflops.

Close behind at No. 3 is the Sunway TaihuLight supercomputer, with an
HPL mark of 93.0 petaflops. TaihuLight was developed by China's
National Research Center of Parallel Computer Engineering and
Technology (NRCPC) and is installed at the National Supercomputing
Center in Wuxi. It is powered exclusively by Sunway's SW26010
processors. Sunway's followed by the Tianhe-2A (Milky Way-2A). This is
a system developed by China's National University of Defense
Technology (NUDT). It's deployed at the National Supercomputer Center
in China. Powered by Intel Xeon CPUs and Matrix-2000 accelerators, it
has a top speed of 61.4 petaflops. Coming at No. 5, the Dell-built,
Frontera, a Dell C6420 system is powered by Intel Xeon Platinum
processors. It speeds along at 23.5 petaflops. It lives at the Texas
Advanced Computing Center of the University of Texas. The most
powerful new supercomputer on the list is Rensselaer Polytechnic
Institute Center for Computational Innovations (CCI)'s AiMOS. It made
the list in the 25th position with 8.0 petaflops. The IBM-built
system, like Summit and Sierra, is powered by Power9 CPUs and NVIDIA
V100 GPUs.

In closing, ZDNet's Steven J. Vaughan-Nichols writes: "Regardless of
the hardware, all 500 of the world's fastest supercomputers have one
thing in common: They all run Linux."'
