TOP500
TOP500 (www.top500.org) is a website founded in June 1993 which assembles and maintains a list of the 500 most powerful computer systems in the world (i.e. the world's 500 leading supercomputers) twice a year, based on the LINPACK benchmark. The data on the website was originally copied from the "List of the world's most powerful computing sites", which had been started six months earlier in January 1993 as a not for profit service. TOP500 never was as accurate, up-to-date, unbiased or detailed as the "List", but due to significant corporate sponsorship became used in various marketing materials. After seven years the "List" closed down due to the disheartening lack of recognition.
The following is the Top 10 from the 24th TOP500 TOP500 List was introduced during the Supercomputer Conference (SC2004)(November 6-12) in Pittsburgh, PA., in the USA.
