dc.description.abstract | they cannot efficiently utilize GPUs for training deep neural networks (DNNs). This is because video decoding in data preparation incurs a prohibitive amount of computing overhead, making GPU idle for the majority of training time. Otherwise, caching raw videos in memory or storage to bypass decoding is not scalable as they account for from tens to hundreds of terabytes. This paper proposes SAND, a system that enables deep learning frameworks to directly access training data by a storage abstraction. This abstraction effectively hides the data preprocessing delay, enabling GPUs to be fully utilized for DNN training. To accomplish this, SAND operates an in-storage cache and manages the cache by ahead-of-time scheduling to guarantee that requested training data can be always retrieved immediately from the cache. This scheduling considers the future data accesses of deep learning frameworks for cache replacement. Compared to the existing approach, our evaluation using emulated environments shows that SAND improves the GPU utilization by 6.0× and reduces the training time by 75.9% on average. | - |
