US, Lenovo retains lead for energy efficient supercomputer
The Henri system at the Flatiron Institute in New York, USA, has kept its crown as the most power efficient supercomputer in the world.
The top 10 spots of the GREEN500 supercomputer energy efficiency listing are occupied by 8 different countries: United States (3 times), France, Australia, Sweden, Spain, Finland, Germany, and South Korea.
The Henri system at number one achieved an energy efficiency rating of 65.40 GFlops/Watt while producing an HPL score of 2.88 PFlop/s and is built by Lenovo with Intel Xeon Platinum and NVIDIA H100. The ThinkSystem SR670 has 8,288 total cores, and while it is still number one in the latest Green 500 listings, it ranks No. 293 on the TOP500 list.
The Frontier Test & Development (TDS) system at ORNL in Tennessee, USA, claims the No. 2 spot with an energy efficiency rating of 62.68 GFlops/Watt and an HPL score of 19.2 PFlop/s. The TDS is basically just one rack identical to the actual Frontier system and utilizes 120,832 total cores.
The No. 3 spot was taken by the Adastra system, which is housed at GENCI-CINES in France. The system achieved an energy efficiency rating of 58.02 GFlops/Watt and a performance of 46.1 PFlop/s. Adastra has 319,072 total cores. The system is built by HP Enterprise and is being upgraded with AMD’s Instinct MI300A Accelerated Processing Unit (APU).

Just like on the last list, the Frontier system at No. 1 on the TOP500 ranks at no 8 for energy efficiency at 52.59 GFlops/Watts. This was the first machine to achieve exascale and shows that power does not need to be sacrificed to achieve an impressive energy efficiency rating.
