This was to mark the beginning of a new era in computer simulation. Besides testing new designs, underground testing had also answered critical questions about the safety, reliability, and performance of existing weapons. If anything, those needs would increase, not decrease, as the US nuclear weapons stockpile aged. So, as part of an effort to address those questions by developing a more thorough scientific understanding of the issues involved, the US Department of Energy propounded the Accelerated Strategic Computing Initiative. ASCI's objective is to support high-confidence assessments and stockpile certifications through high-fidelity simulations. The ASCI program will create these simulation capabilities as part of the DOE's larger Stockpile Stewardship and Management program. The formidable nuclear weapons science issues involved in making this shift will require a significant investment in terms of scientific understanding and funding (ASCI's 1996 annual budget of $85 million rose to $165 in 1998, with more growth expected). This article discusses the steps the ASCI program will take in meeting that challenge.
