El Capitan will be the DOE National Nuclear Security Administration’s first exascale supercomputer. In collaboration with our vendor partners HPE and AMD through the El Capitan Center of Excellence (COE), we have spent several years preparing a variety of scientific applications such that they are scalable and performant on El Capitan on Day 1. In this talk, we will overview the architecture of El Capitan, our software application readiness efforts, discuss the modular software strategy employed by LLNL applications to ensure both performance and portability across modern architectures, provide early glimpses into the expected achievements that El Capitan will enable, and consider lessons learned and best practices developed by the El Capitan COE.
