The most energy-efficient system on the Green500 list is once again the Shoubu system B, a ZettaScaler-2.2 supercomputer installed at the Advanced Center for Computing and Communication, RIKEN, Japan. It was remeasured and achieved 17.6 gigaflops/watt during its 1.06 petaflops Linpack performance run. It occupies position 376 on the TOP500 list.
In second position on the Green500 is the DGX SaturnV Volta system, an NVIDIA system installed at NVIDIA, USA. It achieved 15.1 gigaflops/watt and is in position 375 on the TOP500 list.
At number three is the Summit system at the Oak Ridge National Laboratory (ORNL) in Tennessee. It achieved 14.7 gigaflops/watt and is listed at number one in the TOP500.
Another supercomputer from Japan, AI Bridging Cloud Infrastructure (ABCI) captured the number four spot on the Green500. The system installed at the National Institute of Advanced Industrial Science and Technology (AIST) delivered a power efficiency of 14.4 gigaflops/watt. TSUBAME 3.0, captured the number five spot on the Green500. The Tokyo Tech-based system delivered a power efficiency of 13.7 gigaflops/watt.
Sierra, the AIST AI Cloud, the MareNostrum P9 CTE, Sugon’s Advanced Computing System (PreE) and Taiwania 2 captured the number six through ten positions on the Green500, respectively. The PreE system is powered by the Dhyana CPU, a Hygon-licensed implementation of AMD’s EPYC processor.
