Abstract
This article introduces the photonic network-on-wafer graphics processing unit (GPU) architecture to overcome fundamental limitations in electrical interconnect scaling by implementing the inter-GPU network in a wafer-scale optical interposer. We argue that the photonic-NoW GPU is a scalable architecture, delivering significant performance benefits in a power-efficient manner.
