JAMSTEC ZettaScaler-2.0 Gyoukou is a large GPU cluster operated by Japan Agency for Marine-Earth Science and Technology, located in Japan, in the public sector. It came online around June 2017. At that moment it ranked number 6 among known clusters.
It is built on 1,600 PEZY-SC2. That amounts to about 12.97 H100e of AI compute. The cluster draws roughly 0.32 MW.
Epoch AI rates the certainty of this record as likely. We know that the ZettaScaler 2.2 has 10k processors, can can calculate the number of processors in this supercomputer by scaling by the number of accelerator cores listed in Top500
