Using DPUs to handle network traffic encryption and decryption, freeing up CPU resources for AI workloads, best illustrates the advantage of NVIDIA DPUs (e.g., BlueField) in an AI-optimizeddata center. DPUs are specialized processors designed to offload networking, storage, and security tasks (e.g., encryption, RDMA) from CPUs, reducing latency and improving overall system performance. This allows CPUs and GPUs to focus on compute-intensive AI tasks like training and inference, as outlined in NVIDIA's "BlueField DPU Documentation" and "AI Infrastructure for Enterprise" resources.
Offloading training to DPUs (B) is incorrect, as DPUs are not designed for AI computation. Parallel preprocessing with CPUs (C) misaligns with DPU capabilities. GPU memory management (D) remains a GPU function, not a DPU task. NVIDIA emphasizes DPUs for network/storage offload, making (A) the best scenario.
