This edition of the GREEN500 saw a major shakeup, as all of the Top 3 machines are new to the list.
The No. 1 spot on the GREEN500 was claimed by JEDI - JUPITER Exascale Development Instrument, a new system from EuroHPC/FZJ in Germany. Taking the No. 190 spot on the TOP500, JEDI achieved an energy efficiency rating of 72.73 GFlops/Watt while producing an HPL score of 4.5 PFlop/s. JEDI is a BullSequana XH3000 machine with a Grace Hopper Superchip 72C. It has 19,584 total cores.
The Isambard-AI machine out of the University of Bristol in the U.K. claimed the No. 2 spot with an energy efficiency rating of 68.83 GFlops/Watt and an HPL score of 7.42 PFLop/s. Isambard-AI achieved the No. 129 spot on the TOP500 and has 34,272 total cores.
The No. 3 spot was claimed by the Helios system from Cyfronet out of Poland. The machine achieved an energy efficiency score of 66.95 GFlops/Watt and an HPL score of 19.14 PFlop/s.
Like the last list, the Frontier system deserves an honorable mention when discussing energy efficiency. Frontier achieved an exascale HPL score of 1.206 EFlop/s while also earning an energy efficiency score of 56.97 GFlops/Watt. This places the system at No. 11 on the GREEN500 in addition to its No. 1 spot on the TOP500.
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.
