November 2017

In the latest GREEN500 list, the top three positions are taken by newly installed systems in Japan, all of which are based on the ZettaScaler-2.2 architecture and the PEZY-SC2 accelerator. The SC2 is a second-generation 2048-core chip that provides a peak performance of 8.192 teraflops in single-precision.

The most efficient of these ZettaScaler supercomputers is the Shoubu system B installed at RIKEN’s Advanced Center for Computing and Communication. It achieved a power efficiency of 17.0 gigaflops/watt.

The number two Green500 system is the Suiren2 cluster at the High Energy Accelerator Research Organization/KEK, which managed to reach 16.8 gigaflops/watt.

The number three Green500 slot was captured by the PEZY Computing’s own Sakura system. It achieved 14.2 gigaflops/watt. All of these top three systems are positioned in the bottom half of the TOP500 rankings: Shoubu system B at position 260, Suiren2 at 308, and Sakura at 277.

The fourth greenest supercomputer is a DGX SaturnV Volta system, which is installed at NVIDIA headquarters in San Jose, California. It achieved 15.1 gigaflops/watt, and comes in at number 150 on the TOP500 list. The number five system is Gyoukou, yet another ZettaScaler-2.2 machine.  It achieved an efficiency of 14.2 gigaflops/watt and it currently ranks as the fourth most powerful supercomputer in the world.
