El Capitan has once again asserted its dominance as the world’s fastest supercomputer, retaining its top position on the latest TOP500 list of the most powerful supercomputers. Following closely in the rankings are Frontier and Aurora, which maintain their second and third spots, respectively.
El Capitan, located at the Lawrence Livermore National Laboratory, has further solidified its lead with a performance measured at 1.809 exaflops per second, an increase from its previous score of 1.742 exaflops from June. This significant performance boost is attributed to the expansion of its processing capabilities, now boasting a staggering total of 11.34 million cores powered by AMD’s fourth-generation EPYC processors.
Frontier, hosted at the Oak Ridge National Laboratory, achieved a score of 1.353 exaflops, identical to its June performance, while Aurora at the Argonne Leadership Computing Facility scored 1.012 exaflops, letting both of them retain their rankings.
The fourth position was claimed by JUPITER at the EuroHPC/Jülich Supercomputing Centre in Germany, which recently achieved an exaflop performance for its fully deployed system. This supercomputer utilizes Nvidia’s Grace Hopper chips and boasts a total of approximately 4.8 million cores.
Here’s a summary of the top four supercomputers:
