Question 7
UnclassifiedA data center architect is designing a DGX SuperPOD deployment using BlueField DPUs for network acceleration. The DPUs should offload network processing from the host CPUs. What functions can BlueField DPUs offload in a DGX cluster?
Correct answer: A
Explanation
BlueField DPUs are designed to offload infrastructure work from host CPUs, including "network packet processing," "RDMA operations," "storage virtualization," and security tasks such as "encryption." This lets the DGX host CPUs focus on AI workloads instead of handling data-plane and security processing.
Why each option is right or wrong
A. Network packet processing, RDMA operations, storage virtualization, and security functions like encryption - freeing host CPUs for AI workloads
BlueField DPUs are purpose-built to move data-plane work off the x86 host and into the DPU, so the relevant offloads in a DGX SuperPOD are packet handling, RDMA transport processing, storage virtualization, and security services such as encryption. NVIDIA’s BlueField architecture is specifically positioned as a DPU for infrastructure offload, which is why the host CPUs are preserved for AI compute rather than networking and storage chores.
B. GPU computation offload when host GPUs are busy with training workloads
C. NVLink traffic routing between GPUs within the DGX node
D. CUDA kernel execution for network-related AI inference tasks
