Abstract: Pervasive intelligence promises to revolutionize society from Industrial Internet of Things (IIoT), to smart infrastructure and homes, to personal health monitoring. Unfortunately, many edge devices that are pervasively embedded into infrastructure or implanted into humans are severely resource-constrained. As performing computations at the edge becomes increasingly important to meet latency deadlines and retain sensitive data locally, severe resource constraints present a challenge because many algorithms are too large to fit on a single edge device. In this paper, we focus on distributing inference for neural networks (NNs) with convolution and fully connected layers across multiple edge nodes. In order to improve efficiency on severely resource-constrained edge nodes for diverse NN architectures we present an end-to-end, automated approach, DENNI, that optimizes NN distribution with minimal nodes while meeting memory constraints. When targeting a network of edge nodes with 256KB of non-volatile memory connected with Bluetooth Low Energy, DENNI successfully distributes NN inference for a variety of machine learning algorithms across multiple edge nodes where other, static approaches cannot.
