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 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,[1] a portable implementation of the high-performance LINPACK benchmark written in Fortran for distributed-memory computers.

The most recent edition of TOP500 was published in November 2024 as the 64th edition of TOP500, while the next edition of TOP500 will be published in June 2025 as the 65th edition of TOP500. Since November 2024, the United States' El Capitan is the most powerful supercomputer on TOP500, reaching 1742 petaFlops (1.742 exaFlops) on the LINPACK benchmarks.[2] As of 2018, the United States has by far the highest share of total computing power on the list (nearly 50%).[3] As of 2023, the United States has the highest number of systems with 161 supercomputers, and China is in second place with 104.

The 59th edition of TOP500, published in June 2022, was the first edition of TOP500 to feature only 64-bit supercomputers; as of June 2022, 32-bit supercomputers are no longer listed.[citation needed] The TOP500 list is compiled by Jack Dongarra of the University of Tennessee, Knoxville, Erich Strohmaier and Horst Simon of the National Energy Research Scientific Computing Center (NERSC) and Lawrence Berkeley National Laboratory (LBNL), and, until his death in 2014, Hans Meuer of the University of Mannheim, Germany.[citation needed] The TOP500 project also includes lists such as Green500 (measuring energy efficiency) and HPCG (measuring I/O bandwidth).[citation needed]
