IBM’S Summit and Sierra supercomputers retained the #1 and #2 positions as the world’s fastest computers running the High Performance Linpack (HPL) benchmark, positions they each held since November 2018, reported TOP500.

Summit and Sierra each utilize IBM P9 processors and NVIDIA V100 GPUs and deliver 148.6 HPL petaflops and 94.6 HPL petaflops, respectively. IBM has reported Summits theoretical performance limit is about 200 HPL petaflops.

Summit is deployed at the Oak Ridge National Laboratory and Sierra at California’s Lawrence Livermore Laboratory.

In third place is the Chinese Sunway TaibuLight supercomputer that delivers 93.0 HPL petaflops and uses an astonishing 10 million SW26010 cores. It is installed at the National Computing Center in Wuxi, China.

Tianhe-2A (Milky Way-2A) is the world’s 4th fastest and delivers 61.4 HPL petaflops using Intel Xeon and Matrix-2000 processors. It is installed at China’s National Computer Center in Guanzhou, China.

The fifth fastest and the only new entry into the supercomputer top 10 is the University of Texas’ Frontera system. It is powered by Dell C6420 systems utilizing Intel Xeon Platinum 8280 processors and delivers 23.5 HPL petaflops.

Rounding out the top 10 are:

#6. Piz Daint. Cray XC50 at 20.3 HPL petaflops. Xeon CPUs, NVIDIA P100 GPUs. Switzerland.

#7. Trinity. Cray XC40 at 20.2 HPL petaflops. Xeon and Xeon Phi CPUs. USA

#8. AI Bridge Cloud Infrastructure at 19.9 HPL petaflops. Xeon Gold and NVIDIA Tesla V100 GPUs. Japan.

#9. SuperMU-NG at 19.5 HPL petaflops. Lenovo built using Platinum Xeon CPUs. Germany.

#10. Lassen at 18.2 HPL petaflops. IBM Power 9 and NVIDIA V100 GPUs. USA

China has the greatest number of systems on the TOP500 list with 219, followed by the US with 116, Japan 29, France 19, UK 18 and Germany 14.

However, US has a greater number of systems near the top in performance and thus leads with an overall compute capacity of 38.4% of the lists aggregate compute capability. China ranks second with 29.9% of the lists aggregate compute capability.

Chinese vendors dominate the list with Lenovo claiming 1st place with 173 systems, Inspur 2nd with 71 and Sugon third with 63.  HPE claims 4th place with 40 systems followed by Cray with 39 and European based Bull has 21 systems in the TOP500 list.

IBM’s Roadrunner became the world’s first computer to achieve the 1.0 HPL petaflop milestone in 2008, but now all 500 systems on the TOP500 list achieve an HPL result of at least 1.022 HPL petaflops.
