Machine Learning and Predictive Simulation: HPC and the U.S. Cancer Moonshot

The marriage of experimental science with simulation has been a fruitful one–the fusion of HPC-based simulation and experimentation moves science forward faster than either discipline alone, rapidly testing hypotheses and identifying promising directions for future research. The emergence of machine learning at scale promises to bring a new type of thinking into the mix, incorporating data analytics techniques alongside traditional HPC to accompany experiment. I will discuss the convergence of machine learning, predictive simulation and experiment in the context of one element of the U.S. Cancer Moonshot– a detailed investigation of Ras biology in realistic membranes. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.


Frederick (Fred) Streitz is Chief Computational Scientist and Director of the High Performance Computing Innovation Center (HPCIC) at Lawrence Livermore National Laboratory (LLNL). He develops strategies and leads efforts to address the nation’s forefront scientific problems through development of supercomputing. As HPCIC Director, he helps guide LLNL’s efforts to form strategic industrial, academic and government collaborations that support and expand HPC resources, expertise and capability at the Lab. Both an experimental and computational physicist, his multidisciplinary research teams have twice won the Gordon Bell Prize for significant achievement in supercomputing and were finalists twice more, with work encompassing the fields of material science, turbulence, biomedicine, and plasma science. Dr. Streitz is the chair for the Software Working Group at the Council on Competitiveness and serves on the steering committee for Harvard's Institute for Applied Computational Science, external review panels for Argonne and Oak Ridge National Labs, and the editorial board of the International Journal of High Performance Computing Applications. He is a Fellow of the American Physical Society. Fred joined LLNL in 1999 as a computational physicist after holding positions as a National Research Council Fellow at the Naval Research Laboratory and an Assistant Professor at Auburn University. Dr. Streitz received a Bachelor of Science in physics from Harvey Mudd College in Claremont, California and a Master’s degree and doctorate in physics from the Johns Hopkins University in Baltimore, Maryland.
