GTC 2020 S22009
Presenters: Elena Agostini,NVIDIA; Joe Boccuzzi,NVIDIA
Abstract
NVIDIA Aerial is a set of SDKs that enables GPU-accelerated, software-defined 5G wireless RANs. Today, NVIDIA Aerial provides two critical SDKs: cuVNF (optimized Input/Output leveraged with GPUDirect RDMA) and cuBB (fully-offloaded 5G Signal Processing pipeline). These SDKs can be combined to implement a software-accelerated physical layer on the centralized radio controllers (base band unit) that is able to dialog, by means of a Fronthaul I/O interface, with a set of radio heads to send, receive, and process 5G packets using GPUs. We’ll show our implementation of the Fronthaul I/O interface to enable an ORAN-compliant (O-RAN Alliance) dialog with a radio unit, giving an overview of the most challenging issues we faced in differentiating between hardware- and software-accelerated features.

Hello, great content. However how can I find the specs of the vBBU that you have built? The graph with the performance does not tell me if thoses specs are the ones you used to crate the vBBU. Let´s say that I which to have a 20MHz spectrum with 5G NR, how many GPUs would it require? what about 100 MHz?
