This talk will review NERSC’s efforts in scaling Deep Learning on the largest CPU and GPU-based HPC systems in the DOE complex. Motivated by challenging scientific problems in high-energy physics, cosmology and climate science, we have developed 2D and 3D convolutional architectures to solve a range of pattern classification, regression and segmentation problems. These projects have resulted in a number of first-time results: scaling Caffe to 9600 Cori/KNL nodes (SC’17) obtaining 15PF performance; scaling TensorFlow to 8192 Cori/KNL nodes obtaining 3.5PF performance, and finally, scaling TensorFlow to 4560 Summit/Volta nodes obtaining 1 ExaOp performance. The talk will review lessons learnt from these projects, and outline future challenges in Deep Learning for Science.
