Server load and network-aware adaptive deep learning inference offloading for edge platforms

This work presents DIAMOND, a deep neural network computation offloading scheme consisting of a lightweight client-to-server latency profiling component combined with a server inference time estimation module to accurately assess the expected latency of a deep learning model inference. Latency predictions for both the network and server are comprehensively used to make dynamic (partial) model offloading decisions at the client in run-time. Compared to previous work, DIAMOND targets to minimize network latency estimation overhead and considers the concurrent processing nature of state-of-the-art deep learning inference server designs. Our extensive evaluations with an NVIDIA Jetson Nano client connected to an NVIDIA Triton server shows that DIAMOND completes inference operations with noticeably reduced computational/energy overhead and latency compared to previously proposed model offloading approaches. Furthermore, our results show that DIAMOND well-adapts to practical server load and network dynamics.
