The Fastest Supercomputers in the World

Summit (SuperComputer)

Summit or OLCF-4 is a supercomputer developed by IBM for use at Oak Ridge National Laboratory, which as of November 2019 is the fastest supercomputer in the world, capable of 200 petaFLOPS. [5] [6]  Its current LINPACK benchmark is clocked at 148.6 petaFLOPS. [7]  As of November 2019, the supercomputer is also the 5th most energy efficient in the world with a measured power efficiency of 14.668 gigaFLOPS / watt. [8]  Summit is the first supercomputer to reach exaflop (a quintillion operations per second) speed, achieving 1.88 exaflops during a genomic analysis and is expected to reach 3.3 exaflops using mixed precision calculations.

Sunway TaihuLight

The Sunway TaihuLight Chinese: Shénwēi · tàihú zhī guāng) could be a Chinese supercomputer which, as of November 2018, the TOP500 list, [1] with a LINPACK benchmark rating of 93 petaflops.  [2] The name is as divine power, the sunshine of Taihu Lake.  [3] This is often nearly 3 times as fast because the previous Tianhe-2, which ran at 34 petaflops.  As of June 2017, it’s ranked because the 16th most energy-efficient supercomputer within the Green500, [4] with an efficiency of 6.051 GFlops / watt.  It had been designed by the National Center of Parallel Computer Engineering & Technology (NRCPC) and is found at the National Supercomputing Center in Wuxi within the city of Wuxi, in Jiangsu Province, China.

AI Bridging Cloud Infrastructure (ABCI)

AI Bridging Cloud Infrastructure (ABCI) could be a planned supercomputer being built at the University of Tokyo to be used in AI, machine learning, and deep learning. [4] [5]  it’s being built by Japan’s National Institute of Advanced Industrial Science and Technology.  ABCI is anticipated to be completed in half-moon 2018 with a planned performance of 130 petaFLOPS.  Power consumption is targeting 3 megawatts, and a planned power usage effectiveness of 1.1.  If performance meets expectations, ABCI would be the second most powerful supercomputer built, surpassing this leader Sunway TaihuLight’s 93 petaflops. [6]  But still behind the Summit (supercomputer).
