TOP500 : Ranking of Supercomputers according to the LINPACK benchmark

The TOP500 project ranks and details the 500 (non-distributed) most powerful known 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 one 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, a portable implementation of the High-Performance LINPACK benchmark written in Fortran for distributed-memory computers.
