Using High-Performance Computing to Scale Generative Adversarial Networks
… This thesis achieves this scale up, using Oak Ridge National Labs’ Summit Supercomputer. We observed improvements in the performance of Lipizzaner, especially when run with poorer network architectures, which implies Lipizzaner is able to overcome network limitations through scale.
