The Evolution of Modeling in Science
Abstract:
This talk will present a retrospective on how scientific modeling has evolved at HPC facilities in the Department of Energy. Historically, centers such as Berkeley Lab’s NERSC have primarily supported simulation workloads for over 40 years. These workloads involve running PDE simulations that model complex natural systems (fluid flow, coupled climate model, subsurface flow, etc). Over the past 10 years, data-intensive science has gained prominence: these workloads involve application of statistical or machine learning tools to analyze experimental and observational datasets (from astronomy, cosmology, climate, high-energy physics, etc). We are now witnessing the rise of Deep Learning in Science: domain scientists are augmenting/replacing/enhancing their simulation and analytics models with Deep Learning architectures. This talk will touch upon some leading scientific use cases at NERSC, and conclude with open challenges at the interface of Deep Learning and Scientific Modeling.
