Large-Scale Deep Learning in Heterogeneous Distributed Systems (Xiaowen Chu et al.)

A key driving force of the success of deep learning is the growing computing power of multi-core and many-core processors such as GPUs, FPGA, and ASIC. With the increase of training data size and complexity of deep neural networks, how to efficiently utilize the limited, expensive, and shared computing and communicating resources in a heterogeneous distributed system to support large-scale deep learning tasks from different users becomes an important issue for cloud service providers. Our ultimate goal is to make the deep learning tasks as fast as possible by (1) exploiting the hardware potential to the limit; (2) optimizing the related software components; (3) designing smart resource allocation and task schedule for different simultaneous deep learning tasks.
