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 R
