PEZY dominates the new Green500 list

About a week ago we reported about PEZY reaching the number one spot on the Green500 list with their latest 2,048-core PEZY-SC2 many-core processor. Today, TOP500.org has formally announced their latest November 2017 list.

Dominating the list with four out of the top five most power-efficient systems are the newly installed systems in Japan, all based on the ZettaScaler-2.2 architecture featuring the PEZY-SC2 processors.
