The 63rd edition of the TOP500 reveals that Frontier has once again claimed the top spot, despite no longer being the only exascale machine on the list. Additionally, a new system has found its way into the Top 10.

The Frontier system at Oak Ridge National Laboratory in Tennessee, USA remains the most powerful system on the list with an HPL score of 1.206 EFlop/s. The system has a total of 8,699,904 combined CPU and GPU cores, an HPE Cray EX architecture that combines 3rd Gen AMD EPYC CPUs optimized for HPC and AI with AMD Instinct MI250X accelerators, and it relies on Cray’s Slingshot 11 network for data transfer. On top of that, this machine has an impressive power efficiency rating of 52.93 GFlops/Watt – putting Frontier at the No. 13 spot on the GREEN500.

Also like the last list, the Aurora system at the Argonne Leadership Computing Facility in Illinois, USA, has claimed the No. 2 spot on the TOP500. Despite currently being commissioned and not fully complete, Aurora is now the second machine to officially break the exascale barrier with an HPL score of 1.012 EFlop/s – an improvement over the 585.34 PFlop/s score from the last list. This system is based on HPE Cray EX- Intel Exascale Computer Blade and uses Intel Xeon CPU Max series processors, Intel Data Center GPU Max Series accelerators, and a Slingshot-11 interconnect.

The Eagle system installed on the Microsoft Azure Cloud in the USA reclaimed the No. 3 spot that it achieved after its debut appearance on the previous list, and it remains the highest-ranking cloud system on the TOP500. This Microsoft NDv5 system has an HPL score of 561.2 PFlop/s and is based on Intel Xeon Platinum 8480C processors and NVIDIA H100 accelerators.

Fugaku also retained its No. 4 spot from the previous list, despite holding the No.1 spot from June 2020 until November 2021. Based in Kobe, Japan, Fugaku has an HPL score of 442 PFlop/s and it remains the highest-ranked system outside the USA.
The LUMI system at EuroHPC/CSC in Finland also remained in its spot at No. 5 with an HPL score of 380 PFlop/s. This machine is the largest system in Europe.

The only new system to find its way onto the Top 10 is the Alps machine at No. 6 from the Swiss National Supercomputing Centre (CSCS) in Switzerland. This system achieved an HPL score of 270 PFlop/s.

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.
