The '''TOP500''' project ranks and details the 500 most powerful non-[[Distributed computing|distributed computer]] systems in the world. The project was started in 1993 and publishes an updated list of the [[Supercomputer|supercomputer]]s twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second is presented at the ACM/IEEE Supercomputing Conference in November. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL benchmarks,<ref>{{cite web |url=https://www.netlib.org/benchmark/hpl/ |title=HPL – A Portable Implementation of the High-Performance Linpack Benchmark for Distributed-Memory Computers <!--Version 2.2--> |work=ICL – UTK Computer Science Department |author1=A.

In the early 1990s, a new definition of ''supercomputer'' was needed to produce meaningful statistics. After experimenting with metrics based on processor count in 1992, the idea arose at the [[Organization:University of Mannheim|University of Mannheim]] to use a detailed listing of installed systems as the basis. In early 1993, [[Biography:Jack Dongarra|Jack Dongarra]] was persuaded to join the project with his [[Software:LINPACK benchmarks|LINPACK benchmarks]]. A first test version was produced in May 1993, partly based on data available on the Internet, including the following sources:<ref name="hpcwire">{{cite web |url=https://www.hpcwire.com/archives/10219.html |title=An Interview with Jack Dongarra by Alan Beck, editor in chief HPCwire<!-- Bot generated title --> |archive-url=https://web.archive.org/web/20070928004531/https://www.hpcwire.com/archives/10219.html |archive-date=28 September 2007 |df=dmy-all }}</ref><ref name="netlib">{{cite web |url=http://www.netlib.org/benchmark/top500/reports/report93/section2_16_4.html |title=Statistics on Manufacturers and Continents |access-date=10 March 2007 |archive-date=18 September 2007 |archive-url=https://web.archive.org/web/20070918072815/http://www.netlib.org/benchmark/top500/reports/report93/section2_16_4.html |url-status=live }}</ref>

Since 1993, performance of the {{Numero|1}} ranked position has grown steadily in accordance with [[Moore's law]], doubling roughly every 14 months.

{{As of|2022|08}}, all supercomputers on TOP500 were [[64-bit computing|64-bit]], mostly based on CPUs using the [[X86-64|x86-64]] [[Instruction set architecture|instruction set architecture]]. Of these, 384 are [[Company:Intel|Intel]] EMT64-based and 101 are [[Company:Advanced Micro Devices|AMD]] AMD64-based, with the latter including the top 8 supercomputers. The remaining 15 supercomputers are all based on RISC architectures, including six based on [[AArch64|ARM64]] and seven based on the [[Power ISA]] used by [[Engineering:IBM Power microprocessors|IBM Power microprocessors]].

In recent years heterogeneous computing, mostly using [[Company:Nvidia|Nvidia]]'s [[Graphics processing unit|graphics processing unit]]s (GPUs) or Intel's x86-based [[Engineering:Xeon Phi|Xeon Phi]] as [[Coprocessor|coprocessor]]s, has dominated the TOP500 because of better [[Performance per watt|performance per watt]] ratios and higher absolute performance, while AMD GPUs have taken the top&nbsp;1 and displaced Nvidia in top&nbsp;10 part of the list. The recent exceptions include the aforementioned [[Fugaku (supercomputer)|Fugaku]], [[Sunway TaihuLight]], and K computer. Tianhe-2A is also an interesting exception, as US sanctions prevented use of Xeon Phi; instead, it was upgraded to use the Chinese-designed Matrix-2000<ref>{{Cite web|url= https://en.wikichip.org/wiki/nudt/matrix-2000|title=Matrix-2000 - NUDT |website= WikiChip|access-date=2019-10-06|archive-date= 19 July 2019|archive-url=https://web.archive.org/web/20190719113526/https://en.wikichip.org/wiki/nudt/matrix-2000 |url-status=live}}</ref> accelerators.

A prominent example is the NCSA's [[Blue Waters]] which publicly announced the decision not to participate in the list<ref>{{citation | url = https://www.hpcwire.com/2012/11/16/blue_waters_opts_out_of_top500/ | title = Blue Waters Opts Out of TOP500 | type = article | date = 16 November 2012 | access-date = 30 June 2016 | archive-date = 13 December 2019 | archive-url = https://web.archive.org/web/20191213184408/https://www.hpcwire.com/2012/11/16/blue_waters_opts_out_of_top500/ | url-status = live }}</ref> because they do not feel it accurately indicates the ability of any system to do useful work.<ref>{{citation|author=Kramer, William |title = Top500 versus Sustained Performance{{snd}} Or the Ten Problems with the TOP500 List{{snd}} And What to Do About Them. 21st International Conference On Parallel Architectures And Compilation Techniques (PACT12), 19–23 September 2012, Minneapolis, MN, US}}</ref> Other organizations decide not to list systems for security and/or commercial competitiveness reasons. One such example is the National Supercomputing Center at Qingdao's OceanLight supercomputer, completed in March 2021, which was submitted for, and won, the Gordon Bell Prize. The computer is an exaflop computer, but was not submitted to the TOP500 list; the first exaflop machine submitted to the TOP500 list was Frontier. Analysts suspected that the reason the NSCQ did not submit what would otherwise have been the world's first exascale supercomputer was to avoid inflaming political sentiments and fears within the United States, in the context of the United States – China trade war.<ref>{{cite web | url=https://www.hpcwire.com/2021/11/24/three-chinese-exascale-systems-detailed-at-sc21-two-operational-and-one-delayed/ | title=Three Chinese Exascale Systems Detailed at SC21: Two Operational and One Delayed | date=24 November 2021 | access-date=7 September 2022 | archive-date=2 September 2022 | archive-url=https://web.archive.org/web/20220902060609/https://www.hpcwire.com/2021/11/24/three-chinese-exascale-systems-detailed-at-sc21-two-operational-and-one-delayed/ | url-status=live }}</ref> Additional purpose-built machines that are not capable or do not run the benchmark were not included, such as [[RIKEN MDGRAPE-3]] and [[MDGRAPE-4]]. A Google [[Engineering:Tensor Processing Unit|Tensor Processing Unit]] v4 pod is capable of 1.1 exaflops of peak performance,<ref>{{citation | url = https://cloud.google.com/blog/products/ai-machine-learning/google-wins-mlperf-benchmarks-with-tpu-v4 | title = Google demonstrates leading performance in latest MLPerf Benchmarks | type = article | date = 30 June 2021 | access-date = 10 July 2021 | archive-date = 10 July 2021 | archive-url = https://web.archive.org/web/20210710001251/https://cloud.google.com/blog/products/ai-machine-learning/google-wins-mlperf-benchmarks-with-tpu-v4 | url-status = live }}</ref> however these units are highly specialized to run [[Machine learning|machine learning]] workloads and the TOP500 measures a specific benchmark algorithm using a specific numeric precision.

=== Computers and architectures that have dropped off the list ===
[[IBM Roadrunner]]<ref>{{cite web|url=https://www.top500.org/system/176027|title=Roadrunner{{snd}} BladeCenter QS22/LS21 Cluster, PowerXCell 8i 3.2&nbsp;GHz / Opteron DC 1.8&nbsp;GHz, Voltaire Infiniband|access-date=4 January 2015|archive-date=2 January 2015|archive-url=https://web.archive.org/web/20150102224423/http://www.top500.org/system/176027|url-status=live}}</ref> is no longer on the list (nor is any other using the [[Engineering:Cell (microprocessor)|Cell]] coprocessor, or PowerXCell).

Although [[Engineering:Itanium|Itanium]]-based systems reached second rank in 2004,<ref>{{cite web|url=https://top500.org/system/173300|title=Thunder – Intel Itanium2 Tiger4 1.4 GHz – Quadrics|access-date=4 January 2015|archive-date=2 January 2015|archive-url=https://web.archive.org/web/20150102205559/http://www.top500.org/system/173300|url-status=live}}</ref><ref>{{cite web|url=https://top500.org/system/175560|title=Columbia – SGI Altix 1.5/1.6/1.66&nbsp;GHz, Voltaire Infiniband|access-date=4 January 2015|archive-date=3 January 2015|archive-url=https://web.archive.org/web/20150103041455/http://www.top500.org/system/175560|url-status=live}}</ref> none now remain.

Similarly (non-[[SIMD]]-style) [[Vector processor|vector processor]]s (NEC-based such as the Earth simulator that was fastest in 2002<ref>{{cite web|url=https://top500.org/site/49318|title=Japan Agency for Marine -Earth Science and Technology|access-date=4 January 2015|archive-date=2 January 2015|archive-url=https://web.archive.org/web/20150102205541/http://www.top500.org/site/49318|url-status=live}}</ref>) have also fallen off the list. Also the Sun Starfire computers that occupied many spots in the past now no longer appear.

The last non-Linux computers on the list{{snd}} the two [[Software:IBM AIX|AIX]] ones{{snd}} running on [[Engineering:POWER7|POWER7]]<!--can't see any POWER8 for AIX or non-AIX..--> (in July 2017 ranked 494th and 495th<ref>{{cite web|url=https://www.top500.org/system/178330|title=IBM Flex System p460, POWER7 8C 3.550 GHz, Infiniband QDR|publisher=TOP500 Supercomputer Sites|access-date=6 September 2017|archive-date=3 October 2017|archive-url=https://web.archive.org/web/20171003111249/https://www.top500.org/system/178330|url-status=live}}</ref> originally 86th and 85th), dropped off the list in November 2017.
