The "TOP500" Ranking of Supercomputers Begins

6/1993

In June 1993 Hans Meuer of the University of Mannheim,Germany, Jack Dongarra of the University of Tennessee, Knoxville, and Erich Strohmaier and Horst Simon of NERSC / Lawrence Berkeley National Laboratory began the compilation of the TOP500 project, ranking the 500 most powerful (non-distributedcomputer systems. The project  published an updated list of the supercomputers twice a year. The first of these updates always coincided with the International Supercomputing Conference in June, and the second one was presented in November at the ACM/IEEE Supercomputing Conference.

The project aimed 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.
