Abstract

When there are a lot of training data, or the deep neural network is too large, parallel training becomes essential. Parallel training refers to either data or model parallelism. In both cases, parallel execution introduces various overheads. The research of our group focuses on the development of algorithms and implementation of systems that minimize such overheads. This talk will briefly present four of our proposals: (i) Grace, a framework for the implementation of compressed communication for parallel training; (ii) DeepReduce, a framework for the efficient communication of sparse tensors; (iii) FastBack, a system that reduces the serial delay of backpropagation in model parallelism; and (iv) CompressNAS, an adaptive compressed communication system for Neural Architecture Search.
