Bringing HPC Techniques to Deep Learning - Baidu ResearchSummary: Neural networks have grown in scale over the past several years, and training can require a massive amount of data and computational resources. To provide the required amount of compute power, we scale models to dozens of GPUs using a technique common in high-performance computing (HPC) but underused in deep learning. This technique, the ring allreduce, reduces the amount of time spent co
