###  Executive Summary 

 Our goal is to perform supercomputer simulations of large-scale lattice quantum chromodynamics in order to illuminate a great scientific mystery: the lack of antimatter relative to matter in the universe. Filling this gap in the Standard Model of particle physics will inform research in all missions related to nuclear science.
