cuPHY System Overview

Aerial CUDA-Accelerated RAN 24-1 (Archive)

Aerial cuPHY is a software-defined workload hosted on NVIDIA-certified EGX servers and a stack that uses the CUDA OS platform and GPU/NIC/CPU firmware and toolkits. This section highlights the Aerial cuPHY workload configuration interdependencies as part of the NVIDIA platform stack.
