El Capitan retains No. 1 supercomputer ranking
The El Capitan system at Lawrence Livermore National Laboratory in California maintained its title as the world’s fastest supercomputer, according to the latest TOP500 list released today. U.S.-based systems also won the second and third spots with long-time list leader Frontier at No. 2 and the Aurora system at No. 3.
The El Capitan System debuted in the top spot in November 2024 and continues to lead the pack. The HPE Cray EX255a system, which was measured with 1.742 EFlop/s on the HPL benchmark, has 11,039,616 cores and is based on AMD fourth-generation EPYC processors with 24 cores at 1.8 Ghz and AMD Instinct MI300A accelerators. Using the HPE Slingshot interconnect for data transfer, the El Capitan system achieves an energy efficiency of 60.3 Gigaflops/watt, making it the third system exceeding the Exaflop mark on the HPL benchmark.
In this 65TH edition of the TOP500, the Frontier System at the Oak Ridge National Laboratory, Tennessee, has been remeasured with an HPL score of 1.353 EFlop/s. Based on the HPE Cray EX235z architectures and equipped with AMD third-generation EPYC 64C 2GHz processors, the Frontier systems has 8,699,904 total cores and also relies on HPE Slingshot interconnect for data transfer.
