On the 66th edition of the TOP500 El Capitan remains No. 1 and JUPITER Booster becomes the fourth Exascale system.

The JUPITER Booster system at the EuroHPC / Jülich Supercomputing Centre in Germany at No. 4 submitted a new measurement of 1.000 Exflop/s on the HPL benchmark. It is the fourth Exascale system on the TOP500 and the first one outside of the USA.

El Capitan, Frontier, and Aurora are still leading the TOP500. All three are installed at DOE laboratories in the USA.

The El Capitan system at the Lawrence Livermore National Laboratory, California, USA remains the No. 1 system on the TOP500. The HPE Cray EX255a system was remeasured with 1.809 Exaflop/s on the HPL benchmark. LLNL also achieved 17.41 Petaflop/s on the HPCG benchmark which makes the system the No. 1 on this ranking as well.

El Capitan has 11,340,000 cores and is based on AMD 4th generation EPYC processors with 24 cores at 1.8 GHz and AMD Instinct MI300A accelerators. It uses the Cray Slingshot 11 network for data transfer and achieves an energy efficiency of 60.9 Gigaflops/watt.

The Frontier system at the Oak Ridge National Laboratory, Tennessee, USA is the No. 2 system on the TOP500. Frontier has been remeasured with an HPL score of 1.353 Exaflop/s.

Frontier is based on the HPE Cray EX235a architecture and is equipped with AMD 3rd generation EPYC 64C 2GHz processors. The system has 9,066,176 total cores and also relies on Cray’s Slingshot 11 network for data transfer.

The Aurora system at the Argonne Leadership Computing Facility, Illinois, USA keeps the No. 3 spot on the TOP500 with 1.012 Exaflop/s on the HPL benchmark.

Aurora is built by Intel based on the HPE Cray EX - Intel Exascale Compute Blade which uses Intel Xeon CPU Max Series processors and Intel Data Center GPU Max Series accelerators which communicate through Cray’s Slingshot-11 network interconnect.

The JUPITER Booster system at the EuroHPC / Jülich Supercomputing Centre in Germany at No. 4 is now fully installed and was measured at exactly 1.000 Exaflop/s making it the first European Exascale system.

JUPITER - JU Pioneer for Innovative and Transformative Exascale Research is located at the Forschungszentrum Jülich campus in Germany and is operated by the Jülich Supercomputing Centre. It is based on the Eviden’s BullSequana XH3000
