The focus of the National Security Applications is to deliver comprehensive science-based computational weapons applications able to provide, through effective exploitation of exascale HPC technologies, breakthrough modeling and simulation solutions that yield high-confidence insights into at least three currently intractable problems of interest to the NNSA Stockpile Stewardship Program (SSP).
Multi-physics simulation tools for weapons-relevant applications
Objective: The Ristra project is developing new multi-physics simulation tools that address emerging HPC challenges of massive, heterogeneous parallelism using novel programming models and data management.
The property and behavior of various materials under a wide variety of extreme conditions are central to many applications within the realm of national security. Such modeling requires multiple length and timescales and drives requirements for exascale computing. Los Alamos National Laboratory (LANL) is developing a next-generation multiphysics code for national security applications.

Multi-physics simulation tools for High Energy Density Physics (HEDP) and weapons- relevant applications for DOE and DoD.
Objective: Multi-physics simulation tools for High Energy Density Physics (HEDP) and weapons- relevant applications for DOE and DoD.
The Multi-physics on Advanced Platforms Project (MAPP) is developing next generation multi- physics codes for simulating high-energy-density and focused physics experiments driven by high- explosive, magnetic or laser-based energy sources as well as weapons-relevant simulations. The MAPP approach includes a modular CS infrastructure that serves as the basis of multiple codes, as well as an emphasis on high-order algorithms that are expected to scale better on anticipated architectures.
