This is the final report of the DSB Task Force on NNSAs Strategic Plan for Advanced Computing, co-chaired by Dr. Bruce Tarter and Mr. Robert Nesbit. The Task Force was asked to evaluate NNSAs strategic plan for Advanced Simulation and Computing ASC and its adequacy to support the Stockpile Stewardship Program SSP, whose mission is to ensure the safety, performance and reliability of our Nations nuclear weapons stockpile. The Task Force was also asked to evaluate the role of ASC in maintaining US leadership in advanced computing and assess the impact of using ASCs capabilities for broader national security and other issues. The Task Force concluded that, since the cessation of nuclear testing, ASC has taken on the principal integrating role in assuring the long term safety and reliability of the stockpile. It is also an essential tool in addressing specific stockpile issues. Furthermore, ASC has played a leadership role in reestablishing US leadership in high performance computing. The use of ASC and ASC-derived technology for other national security, scientific, and commercial applications has also increased dramatically, and high performance computing is viewed as an extremely valuable and cost-effective approach to many of the users important problems. However, it is not likely that ASC will meet the compelling goals stated in its roadmaps and planning documents at the currently projected levels of funding. Furthermore, the high end of the US computing industry may be negatively impacted with implications for the much broader range of potential users in the DOD, other federal agencies, and the commercial world. Accordingly, the Task Force strongly recommends sizing the budget of ASC to meet its nuclear weapons objectives and retain US leadership in advanced computing.
