In this paper, we present deep partitioned training to accelerate computations involved in training DNN models. This is the first work that partitions a DNN model across storage devices, an NPU and a host CPU forming a unified compute node for training workloads. To validate the benefit of using the proposed system during DNN training, a trace-based simulator or an FPGA prototype is used to estimate the overall performance and obtain the layer index to be partitioned that provides the minimum latency. As a case study, we select two benchmarks, i.e., vision-related tasks and a recommendation system. As a result, the training time reduces by 12.2~31.0% with four near-storage computing devices in vision-related tasks with a mini-batch size of 512 and 40.6~44.7% with one near-storage computing device in the selected recommendation system with a mini-batch size of 64.
