In response to the unprecedented national security challenges derived from the end of nuclear testing, the Defense Programs of the Department of Energy has developed a long-term strategic plan based on a vigorous Science-Based Stockpile Stewardship (SBSS) program. The main objective of the SBSS program is to ensure confidence in the performance, safety, and reliability of the stockpile on the basis of a fundamental science-based approach. A central element of this approach is the development of predictive, full-physics, full-scale computer simulation tools. As a critical component of the SBSS program, the Accelerated Strategic Computing Initiative (ASCI) was established to provide the required advances in computer platforms and to enable predictive, physics-based simulation technologies. Foremost among the key elements needed to develop predictive simulation capabilities, the development of improved physics-based materials models has been universally identified as one of the highest-priority, highest-leverage activity. We indicate some of the materials modeling issues of relevance to stockpile materials and illustrate how the ASCI program will enable the tools necessary to advance the state-of-the-art in the field of computational condensed matter and materials physics.
