National Security

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).

Ristra

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.

MAPP

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.
