Volume 2 [ONLY]. This item has some waviness. Some pen and ink notations! Illustrated front cover. It starts with the Table of Contents and then goes to Chapter 2 Simulation and Computer Science.(176 pages). Chapter 3 is Integrated Computing Systems (ICS) (50 pages). Chapter 4 is University Partnerships (139, [1] pages). Chapter 5 is ASCI Special Projects (18 pages followed by a distribution list) and appears to complete the implementation plan. Chapter 2 has sections on Problem Solving Environment, Distance and Distributed Computing and Communications (DisCom2), Path Forward, and Visual Interactive Environment for Weapons Simulation (VIEWS). Chapter 3 has sections on Platforms,and Stockpile Computing. Chapter 4 has sections on Academic Strategic Alliance Program, Institutes and Computational Science Graduate Fellowships. Chapter 5 has sections on ASCI SC99 Research Exhibit and One Program--Three Laboratories. While the increase in computing power over the past 50 years has been staggering, the scientific community will require unprecedented computer speeds as well as massive memory and disk storage to address the pressing problems that the nation will face in the 21st century. One such problem is ensuring the safety and reliability of the nation's nuclear arsenal while fully adhering to the Comprehensive Test Ban Treaty. To address this problem, the U.S. Department of Energy (DOE) established the Accelerated Strategic Computing Initiative (ASCI) in 1996. The goal of ASCI is to simulate the results of new weapons designs as well as the effects of aging on existing and new designs, all in the absence of additional data from underground nuclear tests. This is a daunting challenge and requires simulation capabilities that far surpass those available today. With funding from ASCI, the computer industry has already installed three computer systems, one at Sandia National Laboratories (built by Intel), one at Los Alamos National Laboratory (LANL) (an SGI-Cray computer), and another at Lawrence Livermore National Laboratory (LLNL) (an IBM computer), that can sustain more than 1 teraflops on real applications. At the time they were installed, each of these computers was as much as 20 times more powerful than those at the National Science Foundation (NSF) Supercomputer Centers, the National Energy Research Supercomputing Center, and other laboratories. By 2002, the computer industry planned to deliver a system 10 times more powerful than these two systems and, in between, another computer will be delivered that has three times the power of the LANL/LLNL computers. The ASCI is an applications-driven effort with a goal to develop reliable computational models of the physical and chemical processes involved in the design, manufacture, and degradation of nuclear weapons. Based on detailed discussions with scientists and engineers with expertise in weapons design, manufacturing, and aging and in computational physics and chemistry, a goal of simulating full-system, three-dimensional nuclear burn and safety simulation processes was established. A number of intermediate, applications-based milestones were identified to mark the progress from our current simulation capabilities to full-system simulation capabilities.
