"They trained the GAN on the Summit supercomputer, which (as of the June 2019 Top500 list) remains the world’s fastest publicly-ranked supercomputer at 148.6 Linpack petaflops. The team achieved peak and sustained performance of 1.2 exaflops, scaling to 27,504 of Summit’s Nvidia V100 GPUs and 4,584 of its nodes. .This physics-informed GAN, trained by HPC, allowed the researchers to quantify their uncertainties about the subsurface flow in the site."
