This paper documents the need for a rapid, order-of-magnitude increase in the computing infrastructure provided to scientists working in the unclassified domains at Lawrence Livermore National Laboratory. This proposed increase could be viewed as a step in a broader strategy linking hardware evolution to applications development that would take LLNL unclassified computational science to a position of distinction, if not preeminence, by 2006. We believe that it is possible for LLNL institutional scientists to gain access late this year to a new system with a capacity roughly 80% to 200% that of the 12-TF/s (twelve trillion floating-point operations per second) ASCI White system for a cost that is an order of magnitude lower than the White system. This platform could be used for first-class science-of-scale computing and for the development of aggressive, strategically chosen applications that can challenge the near PF/s (petaflop/s, a thousand trillion floating-point operations per second) scale systems ASCI is working to bring to the LLNL unclassified environment in 2005. As the distilled scientific requirements data presented in this document indicate, great computational science is being done at LLNL--the breadth of accomplishment is amazing. The computational efforts make it clear what a unique national treasure this Laboratory has become. While the projects cover a wide and varied application space, they share three elements--they represent truly great science, they have broad impact on the Laboratory's major technical programs, and they depend critically on big computers.
