NexGen Cloud Hyperstack AQ Compute Supercomputer is a large GPU cluster operated by NexGen Cloud, located in Norway, in the private sector. It came online around April 2024. At that moment it ranked number 3 among known clusters.
It is built on 16,384 NVIDIA H100 SXM5 80GB. That amounts to about 16.4K H100e of AI compute. The cluster draws roughly 23.38 MW. Its hardware is estimated at $583M.
Epoch AI rates the certainty of this record as likely. They seem to be stating that all 16k GPUs are in the same physical location, but I'm not fully confident in this
