== Achtergrond ==
=== Tianhe-1 ===
[[Tianhe]]-1 werd ontwikkeld door het [[National University of Defense Technology|Chinese National University of Defense Technology (NUDT)]] in [[Changsha]], [[Hunan]]. Hij werd voor het eerst aan het publiek getoond op {{Nowrap|29 oktober}} 2009, en werd onmiddellijk gerangschikt als nummer 5 op de lijst van snelste supercomputers van de [[Supercomputing Conference]] in 2009 (SC09) gehouden in [[Portland, Oregon|Portland]], [[Oregon]]. Tianhe haalde 563 [[FLOPS|teraflops]] in zijn eerste test en een piek van 1,2 petaflops. Het systeem had bij het opstarten dus een efficiëntie van 46%.<ref name="BBC">{{cite news |url=http://news.bbc.co.uk/2/hi/technology/8362825.stm |title=China joins supercomputer elite |date=16 november 2009 |publisher=BBC |accessdate=16 november 2009}}</ref><ref name="PC World">{{cite news |url=http://www.pcworld.com/businesscenter/article/182225/two_rival_supercomputers_duke_it_out_for_top_spot.html |title=Two Rival Supercomputers Duke It out for Top Spot |date=15 november 2009 |publisher=PC World |accessdate=16 november 2009 |archiefdatum=19 november 2009 |archiefurl=https://web.archive.org/web/20091119054551/http://www.pcworld.com/businesscenter/article/182225/two_rival_supercomputers_duke_it_out_for_top_spot.html |dodeurl=ja }}</ref> Oorspronkelijk bestond Tianhe-1 uit 4.096 Intel [[Xeon]] E5540-processoren en 1.024 Intel Xeon E5450-processoren, met 5.120 [[Advanced Micro Devices|AMD]]-[[Graphics processing unit|GPU]]'s.<ref name="AMD PR">{{cite news |url=http://www.amd.com/us/press-releases/Pages/powerful-supercomp-2009nov16.aspx |title=Most Powerful Supercomputer in the World Powered by the Six-Core AMD Opteron Processor |date=16 november 2009}}</ref><ref>{{cite web |url=http://www.top500.org/blog/2009/11/13/tianhe_1_chinas_first_petaflop_s_scale_supercomputer |title=Tianhe-1, China's first Petaflop/s scale supercomputer |date=13 november 2009 |author= |work=Top 500 blog |bezochtdatum=31 oktober 2010 |archiefdatum=1 december 2010 |archiefurl=https://web.archive.org/web/20101201085711/http://top500.org/blog/2009/11/13/tianhe_1_chinas_first_petaflop_s_scale_supercomputer |dodeurl=ja }}</ref>
