Editing Opteron (section)

==Supercomputers==

Opteron processors first appeared in the top 100 systems of the [[TOP500|fastest supercomputers in the world]] list in the early 2000s.  By the summer of 2006, 21 of the top 100 systems used Opteron processors, and in the November 2010 and June 2011 lists the Opteron reached its maximum representation of 33 of the top 100 systems.   The number of Opteron-based systems decreased fairly rapidly after this peak, falling to 3 of the top 100 systems by November 2016, and in November 2017 only one Opteron-based system remained.<ref>{{cite web|url=https://www.top500.org/list/2016/11/?page=1|publisher=[[TOP500]]|title=TOP500 List – November 2016|access-date=2017-02-21}}</ref><ref>{{cite web|url=https://www.top500.org/list/2017/11/|publisher=[[TOP500]]|title=TOP500 List – November 2017|access-date=2018-01-09|archive-date=April 5, 2020|archive-url=https://web.archive.org/web/20200405052427/https://www.top500.org/list/2017/11/|url-status=dead}}</ref>

Several supercomputers using only Opteron processors were ranked in the top 10 systems between 2003 and 2015, notably:

* Red Storm – [[Sandia National Laboratories]] – {{Numero|2}} system in November 2006.
* Jaguar – [[Oak Ridge National Laboratory]] – various configurations held top 10 positions between 2005 and 2011, including {{Numero|1}} in November 2009 and June 2010.
* Ranger – [[Texas Advanced Computing Center]] – {{Numero|4}} system in June 2008.
* Kraken – [[National Institute for Computational Sciences]] – {{Numero|3}} system in November 2009.
* Hopper – [[National Energy Research Scientific Computing Center]] – {{Numero|5}} system in November 2010.

Other top 10 systems using a combination of Opteron processors and [[compute accelerators]] have included:

* [[IBM Roadrunner]] – [[Los Alamos National Laboratory]] – {{Numero|1}} system in 2008.  Composed of Opteron processors with IBM [[Cell (microprocessor)|PowerXCell 8i]] co-processors.

The only system remaining on the list (as of November 2017), also using Opteron processors combined with compute accelerators:

* [[Titan (supercomputer)]] – [[Oak Ridge National Laboratory]] – {{Numero|1}} system in 2012, {{Numero|5}} as of November 2017.  Composed of Opteron processors with [[Nvidia]] [[Fermi (microarchitecture)]] GPU-based accelerators.
