The No. 1 spot on the GREEN500 was again earned by the Henri system at the Flatiron Institute in New York City, United States, with an energy efficiency of 65.40 Gflops/Watt. What’s more, improvements to the system allowed it to achieve an impressive jump on the TOP500 list from the No. 405 spot to No. 255 with a current HPL score of 2.88 Pflop/s – an increase over last list’s score of 2.038 Pflop/s. Henri has 8,288 and is a Lenovo ThinkSystem SR670 with Intel Xeon Platinum and Nvidia H100.
The No. 2 spot was achieved by the Frontier Test & Development System (TDS) at ORNL in the United States with an energy efficiency rating of 62.20 Gflops/Watt. The Frontier TDS system is simply a single rack identical to the actual Frontier system and has an HPL score of 19.2 Pflop/s.
The No. 3 spot was taken by the Adastra system. A HPE Cray EX235a system with AMD EPYC and AMD Instinct MI250X.
Additionally, the actual Frontier system deserves an honorable mention in terms of its energy efficiency. Despite its No.1 spot on the TOP500 list with an HPL score of 1.194 Eflop/s, this machine was still able to achieve a No. 6 spot on the GREEN500 with an energy efficiency rating of 52.59 Gflops/Watt.
The HPL performance of each of these systems proves that immense power does not have to come at the cost of inefficient energy usage.
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.
