Green500 Rankings: Top Ten Supercomputers See Shake-Up

The landscape of supercomputing has seen a significant shift as Europe now boasts the top three most power-efficient supercomputers in the world. This marks a notable achievement for the region, showcasing its commitment to energy efficiency and technological advancement.

Leading the pack is the JEDI (JUPITER Exascale Development Instrument) system, developed by EuroHPC/FZJ in Germany. While ranking 190th on the TOP500 list, JEDI secured the top spot on the GREEN500 with an impressive energy efficiency rating of 72.73 GFlops/Watt and an HPL score of 4.5 PFlop/s. Powered by a BullSequana XH3000 machine with a Grace Hopper Superchip 72C, JEDI houses a total of 19,584 cores.

Securing the second position is the Isambard-AI supercomputer from the University of Bristol in the UK. With an energy efficiency rating of 68.83 GFlops/Watt and an HPL score of 7.42 PFLop/s, Isambard-AI has proven its prowess in the realm of supercomputing.

Claiming the third spot is the Helios system developed by Cyfronet in Poland. Boasting an energy efficiency score of 66.95 GFlops/Watt and an impressive HPL score of 19.14 PFlop/s, Helios has solidified its position as a key player in the global supercomputing arena.

Noteworthy mentions include the Frontier system, which achieved an exascale HPL score of 1.206 EFlop/s and an energy efficiency score of 56.97 GFlops/Watt, earning it the 11th spot on the GREEN500 list and the top spot on the TOP500, further highlighting its exceptional performance.
