On the 67th edition of the TOP500, LineShine debuts as the new No. 1 system, ending El Capitan's run atop the list and becoming the fifth Exascale system overall. It is the first China-based system to lead the TOP500 since Sunway TaihuLight in 2017.
LineShine is installed at the National Supercomputing Centre in Shenzhen (NSCS), China, and was built by the Shenzhen Cloud Computing Center. It submitted a debut measurement of 2.198 Exaflop/s on the HPL benchmark, more than 20% ahead of the No. 2 system, using 13,789,440 cores. The system is based on the custom "LingKun" platform with 304-core LX2 processors running at 1.55 GHz, the proprietary LingQi interconnect, and Kylin OS. LineShine also takes over the No. 1 spot on the HPCG ranking with 22.00 Petaflop/s. On the HPL-MxP benchmark, which measures mixed-precision performance, LineShine debuts in fourth at 7.92 Exaflop/s with a more modest 3.6x speedup, consistent with its CPU-only design.
El Capitan, Frontier, Aurora, and JUPITER Booster all remain Exascale-class systems and now occupy No. 2 through No. 5, all still installed at the same sites as last edition.
The El Capitan system at the Lawrence Livermore National Laboratory, California, USA, moves to No. 2 on the TOP500. The HPE Cray EX255a system holds at 1.809 Exaflop/s on the HPL benchmark. LLNL's 17.41 Petaflop/s on HPCG now places the system No. 2 on that ranking as well, behind LineShine.
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 60.94 Gigaflops/watt.
The Frontier system at the Oak Ridge National Laboratory, Tennessee, USA, is the No. 3 system on the TOP500, holding at 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, holds the No. 4 spot on the TOP500 with 1.012 Exaflop/s on the HPL.
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 communicating through Cray's Slingshot-11 interconnect.
The JUPITER Booster system at the EuroHPC / Jülich Supercomputing Centre in Germany moves to No. 5, still measured at exactly 1.000 Exaflop/s and remaining 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 Eviden's BullSequana XH3000 direct liquid-cooled architecture, utilizing Grace Hopper Superchips.
Rmax and Rpeak values are in PFlop/s. For more details about other fields, check the TOP500 description.
Rpeak values are calculated using the advertised clock rate of the CPU. For the efficiency of the systems you should take into account the Turbo CPU clock rate where it applies.
