Book Description
The long, drawn-out and expensive acquisition process in the military is a serious problem at any time, but especially so in these times of tight and declining budgets. HPC has been used, on occasion, by the military and some large companies to speed the acquisition and design process by using computer modeling and computer experimentation in place of the much longer and more expensive traditional process of building prototypes, testing, redesigning, building more prototypes, and more testing, until the design is final. The authors begin with a discussion of the growth and trends in HPC, then discuss how the Army has utilized HPC in research. Included here is the Army's exploration of the possibilities for design and production of new systems. Turning to manufacturing-related topics, the authors then discuss how industry has advanced the use of HPC and include several case histories. Next, they present some contributions to HPC advancement in several current programs being conducted by other government agencies. The paper concludes with closing comments and recommendations for strengthening Army acquisition using advanced computer technology.

Book Description
The long, drawn- out and expensive acquisition process in the military is a serious problem at any time, but especially so in these times of tight and declining budgets. Many times the Department of Defense (DOD) has been criticized for the manner by which it procures new weapons systems. Recent articles in the Washington Post1,2 and Defense News 3 review the Army acquisition process, presenting an analysis of some $38 billion spent on system s that were terminated for high costs and lengthy development times. Two cases in point that f ailed: the Crusader artillery system which foundered, in part, on the failure of a new propellant system , high costs, and a too-long development cycle, and the Comanche stealth helicopter, again terminated because of cost overrun s and slippage of schedules. The available funding for the Comanche was redirected into buying and upgrading existing helicopter program s where the procurement risks were reduced. A question is how much of this problem is due to technical inefficiencies, and how much is due to other factors such as the requirements process, Defense acquisitions regulations, and the complexity of the lengthy budgeting process or changes in the governing political system . We seek to show how one factor, the expanded use of high performance computing, can contribute to improving the design and production of weapons systems. This would contribute to a more responsive, more economical acquisition process.

Book Description
Members of this project have studied the academic and industrial uses of High Performance Computing (HPC) and have conducted site visits at a number of Army R & D HPC user and provider sites, including the Medical Research and Materiel Command (MRMC), Edgewood Chemical Biological Center (ECBC), the Army Research Lab's Major Shared Resource Center (MSRC), the Developmental Test Command (DTC), Research, Development, and Engineering Command's (RDECOM's) Communications- Electronics Research, Development, and Engineering (RD & E) Center (CERDEC), Scalable Network Technologies, Inc., and the Director for Command, Control, Communication, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) for Future Combat Systems (FCS) at Boeing, Huntington Beach, California. Because of the breadth of possible uses of HPC in Army R & D, our client asked us to concentrate on two HPC application areas: biotechnology and biomedicine, and modeling and simulation of the complex battlefield wireless network communication systems. We did so, and concluded that these areas are of great importance and merit focused funding and attention.

Book Description
The purpose of this study was to identify key potential users of high-performance computing (HPC) within the Army science and technology community and any barriers that prevent full use of current and planned HPC resources. A main study goal was to help develop an Army HPC strategy and build an HPC initiative that facilitates that strategy, thereby allowing the Army to compete effectively for Department of Defense HPC resources and to ensure that they are used for maximum effect in attacking the most difficult and computationally intensive research problems critical to future force and future combat systems achievement. Particular attention was given to applications of HPC in biotechnology and biomedicine and modeling and simulation of complex battlefield wireless network communication systems.

Book Description
High performance computing (HPC) has historically played a major role in the ability of the United States to develop and deploy superior weapons, warfighting capabilities, and mission support systems. Under the auspices of the Director, Defense Research and Engineering (DDR & E), the Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP) is the focused modernization effort within the DoD to acquire, manage, and sustain modern HPC resources in support of defense science and technology, and developmental test and evaluation. The HPCMP is rapidly evolving past its initial program development and procurement start up phase and is increasing focus on application of HPC technology and resources to priority defense requirements. This plan describes some of the accomplishments achieved by the program in Fiscal Year (FY) 1997 and outlines the major strategies and milestones we expect to achieve over the next two years. The overriding goal of the program is to exploit HPC technology for military advantage across battlespace. The strategy to achieve this goal is to acquire and sustain world class high performance computing and network capabilities for use by defense scientists and engineers.

Book Description
High-performance computing (HPC) is in a state of transition. HPC users have traditionally relied upon two things to supply them with processing power: speed of the central processing units (CPUs) and the scalability of the system. There are problems with this approach. Physical limitations are curtailing clock speed increases in general-purpose CPUs, the von Neumann load-execute-store approach does not map well to every computational problem, and systems of thousands of processors might be very inefficient depending upon processor interconnection limitations. Several versatile, commodity-based options are coming on line that could help address these deficiencies. Options now include throughput architectures such as graphics processing units (GPUs), reconfigurable systems built on field programmable gate arrays (FPGAs), multi- and many core x86-based systems, and heterogeneous systems such as the Cell processor (incorporating a standard CPU and vector processing units). Each of these can be used to provide performance that, at one time, was only available by using Application Specific Integrated Circuits (ASICs) or large-scale fixed HPC assets. Newer methodologies hold out the hope of being more cost efficient and deployable along with providing faster deployment and development times and allowing the use of algorithms that remain modifiable at all stages of development and fielding. This report discusses our research on blending these asymmetric computing resources and addresses their use from the U.S. Army HPC perspective. We focus on the different methodologies and discuss performance from the perspective of kernels and applications that are relevant to fielding HPC technologies that will benefit the U.S. Army warfighter.
