The TOP500 project ranks and details the 500 most powerful (non-distributed) computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second is presented in November at the ACM/IEEE Supercomputing Conference. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL,〔(【引用サイトリンク】title=HPL - A Portable Implementation of the High-PerformanceLinpack Benchmark for Distributed-Memory Computers )〕 a portable implementation of the high-performance LINPACK benchmark written in Fortran for distributed-memory computers. The TOP500 list is compiled by Jack Dongarra of the University of Tennessee, Knoxville, Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory (and, from 1993 until his death in 2014, Hans Meuer of the University of Mannheim, Germany.) == History == 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 was born at the University of Mannheim to use a detailed listing of installed systems as the basis. In early 1993, Jack Dongarra was persuaded to join the project with his LINPACK benchmark. A first test version was produced in May 1993, partially based on data available on the Internet, including the following sources:〔 〕〔 (Statistics on Manufacturers and Continents )〕 * "List of the World's Most Powerful Computing Sites" maintained by Gunter Ahrendt〔(【引用サイトリンク】title=The TOP25 Supercomputer Sites )〕 * David Kahaner, the director of the Asian Technology Information Program (ATIP),〔(【引用サイトリンク】title=Where does Asia stand? This rising supercomputing power is reaching for real-world HPC leadership. )〕 in 1992 had published a report titled ''"Kahaner Report on Supercomputer in Japan"''〔 which had an immense amount of data. The information from those sources was used for the first two lists. Since June 1993, the TOP500 is produced bi-annually based on site and vendor submissions only. Since 1993, performance of the #1 ranked position has steadily grown in agreement with Moore's law, doubling roughly every 14 months. , the fastest system, the ''Tianhe-2'' with a Rpeak〔''Rpeak'' – This is the theoretical peak performance of the system. Measured in PFLOPS.〕 of 54.9024 PFLOPS, is over 419,102 times faster than the fastest system in November 1993, the Connection Machine CM-5/1024 (1024 cores) with Rpeak of 131.0 GFLOPS.〔(【引用サイトリンク】title=Sublist Generator )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TOP500」の詳細全文を読む スポンサード リンク
