Energy efficiency on the list continues to rise, as reflected in the latest Green500 results. The top four positions are all occupied by newly installed systems in Japan, with the upgraded Piz Daint supercomputer capturing the number five spot. All of these use NVIDIA’s latest P100 GPUs. In fact, the top 13 systems on the latest Green500 are all equipped with the P100 hardware.
The most energy-efficient system on the Green500 list is the new TSUBAME 3.0, a modified HPE ICE XA system installed at the Tokyo Institute of Technology. It achieved 14.110 gigaflops/watt during its 1.998-petaflop Linpack performance run. It is ranked number 61 on the TOP500 list.
The number two Green500 entry is the kukai system at the Yahoo Japan Corporation. Built by Exascaler, this system achieves 14.045 gigaflops/watt, just 0.3 percent behind TSUBAME 3.0. It occupies position 466 on the current TOP500 list.
The number three system on the Green500 list is the AIST AI Cloud system at the National Institute of Advanced Industrial Science and Technology, Japan. This system from NEC achieves 12.68 gigaflops/watt and is ranked number 148 on the TOP500.
The number four Green500 system is the RAIDEN GPU system, manufactured by Fujitsu. It is installed at RIKEN’s Center for Advanced Intelligence Project. It attained 10.6 gigaflops/watt and is in position 306 on the TOP500 list.
Piz Daint, the fifth-ranked supercomputer on the Green500, conducted a power-optimized run of the Linpack benchmark, achieving 10.4 gigaflops/watt. At number three on the TOP500, it represents the most energy-efficient supercomputer in the top 50 of that list.
