AI Bridging Cloud Infrastructure (ABCI) is a planned supercomputer being built at the University of Tokyo for use in artificial intelligence, machine learning, and deep learning.{{cite news|last1=Moody|first1=Glyn|title=Japan plans 130-petaflop China-beating number-crunching supercomputer|url=https://arstechnica.com/business/2016/11/supercomputer-japan-130-petaflop-china-beating-number-cruncher/|accessdate=25 November 2016|publisher=Ars Technica|date=25 November 2016}}{{cite news|last1=Sayer|first1=Peter|title=Japan aims for superefficient supercomputer by 2017|url=http://www.computerworld.com/article/3144925/cloud-computing/japan-aims-for-superefficient-supercomputer-by-2017.html|accessdate=25 November 2016|publisher=Computer World|date=25 November 2016}} It is being built by Japan's National Institute of Advanced Industrial Science and Technology. ABCI is expected to be completed in first quarter 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 the current leader Sunway TaihuLight's 93 petaflops.{{cite news|last1=Doran|first1=Temujin|last2=Scott|first2=Katy|title=Japan is building the fastest supercomputer ever made|url=http://www.cnn.com/2017/06/13/tech/supercomputer-japan/index.html|accessdate=7 November 2017|publisher=CNN|date=31 July 2017}} But still behind the Summit supercomputer.
History
In November 2014 it was announced that a 160 petaFLOPS system will be built for {{yen|19.5 billion}} ({{USD|172.4 million}} – {{USD|231.8 million}}), with construction to begin in 2017.{{cite news|last1=Jones|first1=Rhett|title=Japan Throws Down The Gauntlet With Plan For World's Fastest Supercomputer|url=http://www.gizmodo.com.au/2016/11/japan-throws-down-the-gauntlet-with-plan-for-worlds-fastest-supercomputer/|accessdate=25 November 2016|publisher=Gizmodo|date=26 November 2016}}
In October 2017 Fujitsu got the contract to build a 37 petaFLOPS system for {{USD|44.3 million}}.{{cite web | url=https://www.top500.org/news/fujitsu-to-build-japans-fastest-computer/ | last1=Feldman |first1=Michael | title=Fujitsu to Build Japan's Fastest Supercomputer | date=2017-10-11 | publisher=top500.org | archiveurl = https://web.archive.org/web/20171011062904/https://www.top500.org/news/fujitsu-to-build-japans-fastest-computer/ | archivedate = 2017-10-11 | accessdate=2017-11-07}}{{cite news | last1=Moss | first1=Sebastian | title=Fujitsu to build Japan's fastest supercomputer for AIST | url=https://www.datacenterdynamics.com/news/fujitsu-to-build-japans-fastest-supercomputer-for-aist/ | accessdate=17 August 2019 | publisher=Data Centre Dynamics | date=10 October 2017}}
Design
The design of the ABCI is to be focused on low precision floating point, big data, and artificial intelligence applications; rather than Linpack performance.{{cite news|last1=Brueckner|first1=Rich|title=Japan to Build 130 Petaflop ABCI Supercomputer|url=http://insidehpc.com/2016/11/abci-supercomputer/|accessdate=25 November 2016|publisher=InsideHPC|date=25 November 2016}}
Projects
The ABCI is planned to be available to Japanese corporations, small businesses, and researchers; reducing their dependence on foreign cloud computing providers such as Microsoft and Google.
