The system to claim the No. 1 spot for the GREEN500 is the Frontier Test & Development System (TDS) at ORNL in the US. With 120,832 total cores and an HPL benchmark of 19.2 PFlop/s, the Frontier TDS machine is basically just one rack identical to racks in the actual Frontier system. Therefore, it makes sense that it is outmatched by Frontier’s 8,730,112 cores and HPL benchmark of 1.102 Exaflop/s. However, Frontier TDS has some impressive efficiency capabilities. With a power efficiency of 62.8 gigaflops/watt, Frontier TDS is the clear leader of the GREEN500.

Continuing with this trend, and perhaps even redefining it, is the original Frontier system at ORNL in the US. This machine earned the highest spot on the TOP500 list and was still able to take the No. 2 spot on the GREEN500. This system is able to produce a whopping 1.102 Exaflop/s HPL benchmark score while keeping its power efficiency at 55.23 gigaflops/watt. Considering this machine was able to stay competitive on the GREEN500 while becoming the first exascale system shows how energy efficiency is becoming a top priority for HPC facilities.

The No. 3 spot was taken by the LUMI system, which is quite an accomplishment for the newcomer. Despite being the largest system in Europe, LUMI has an impressive power efficiency rating of 51.63 gigaflops/watt.

In fact, LUMI is part of a wider trend in HPC that is proving that power doesn’t have to be sacrificed in the name of efficiency. The No. 4 spot was held by Adastra, an HPE Cray EX system at GENCI-CINES that took the No. 10 spot on the TOP500. It’s also the second fastest in Europe and has an efficiency rating of 50.03 gigaflops/watt.

Last year’s winner of the GREEN500 has moved down to the No. 5 spot, as the MN-3 system from Preferred Networks in Japan received a power efficiency rating of 40.90 gigaflops/watt. This is an improvement over the system’s previous score of 39.38 gigaflops/watt.
