Correspondence issued by the General Accounting Office with an abstract that begins "GAO examined Navy inventory management activities to determine whether any unauthorized activity codes had been used to requisition new and excess property. GAO found that as of June 2000, the Navy maintained 2,002 activity codes identified as unauthorized to requisition government property. However, during the last five years, 663 of these codes were used to requisition more than $2 billion in new and excess government property. In addition, there were no safeguards in the Defense Automatic Addressing System Center or the Defense Reutilization and Marketing Service to prevent these activity codes from being used. This has created a condition in which government property is vulnerable to waste, fraud, and abuse."

Correspondence issued by the General Accounting Office with an abstract that begins "This report discusses the use of intellectual property generated at the Department of Energy's (DOE) laboratories to satisfy defense contractors' offset requirements. GAO found that DOE's laboratory offset requirements have been limited. GAO's discussions with DOE and laboratory management contractors uncovered only 14 instances in which the laboratories' intellectual property were involved in offset projects. GAO also found that management contractors have the right to intellectual property that they produce at DOE laboratories."

Correspondence issued by the General Accounting Office with an abstract that begins "GAO examined the military's inventory management activities to determine if activity codes identified as unauthorized to requisition had been used to buy property for the Air Force. GAO found that as of June 2000, the Air Force maintained 4,239 activity codes identified as unauthorized to requisition government property. However, during the last five years, 193 of these codes were inappropriately used to requisition nearly $23 million in new and excess government property. In addition, safeguards established to prevent unauthorized activity codes from being used to requisition government property failed. This situation has created a condition in which government property is vulnerable to waste, fraud, and abuse."

Correspondence issued by the General Accounting Office with an abstract that begins "As of June 2000, the General Services Administration (GSA) maintained 52 activity codes identified as unauthorized to requisition government property. During the last five years, four of these codes were inappropriately used to requisition about $3,000 in new and excess government property. Although this amount represents a small percentage of total GSA requisitions made during the five-year period, existing safeguards are inadequate to prevent the use of unauthorized activity codes to requisition government property. GSA is now tracing the various items."

Increasingly in industry, software design and implementation is object-oriented, developed in C++ or Java, and relies heavily on pre-existing software libraries (e.g. the Microsoft Foundation Classes for C++, the Java API for Java). A similar but more tentative trend is developing in high-performance parallel scientific computing. The transition from serial to parallel application development considerably increases the need for library support: task creation and management, data distribution and dynamic redistribution, and inter-process and inter-processor communication and synchronization must be supported. PADRE is a library to support the interoperability of parallel applications. We feel there is significant need for just such a tool to compliment the many domain-specific application frameworks presently available today, but which are generally not interoperable.

Modern antennas especially arrays are being placed in layers of materials on complex environments. This technique produces aesthetically pleasing structures if necessary, allows for more freedom in structure planning, and can improve antenna performance. In the past, buried antennas have been studied by numerous authors such as in Reference. Recent work on this subject uses spectral and/or numerical moment method formulations. For high frequency analysis it is important to find efficient and accurate methods for design purposes. A rigorous recursive method for plane waves reflection and transmission coefficients by Richmond has been used in the past for dipoles above multilayer slabs. This solution is modified in this paper to account for forward and backward traveling rays with appropriate spread factors for a dipole in the media. Extensive validation for this approximate method shows good agreement with a Method of Moments code. This code is developed at Lawrence Livermore National Laboratory. The geometry for these comparisons uses a dipole in nontruncated dielectric multilayer slabs.

Some recent work has been done to look at improvements of transporting beam from the Lithium Lens to the Debuncher. This work has been done using the beamline modeling tools developed by Dave McGinnis. These tools, console application P143 and optimization code running MAD repeatedly on the Beam Physics UNIX system, were first used to match the Twiss and dispersion parameters at the end of AP2 to the Debuncher. Imaginary trims were then added to AP2 to study where additional trims could be used to help with beam control in small aperture areas.

The authors discuss the decay of axion walls bounded by strings and present numerical simulations of the decay process. In these simulations, the decay happens immediately, in a time scale of order the light travel time, and the average energy of the radiated axions is <w{sub a}> {approx_equal} 7m{sub a} for v{sub a}/m{sub a} {approx_equal} 500. <w{sub a}> is found to increase approximately linearly with ln(v{sub a}/m{sub a}). Extrapolation of this behavior yields <w{sub a}> {approx_equal} 60 m{sub a} in axion models of interest.

Adaptive mesh refinement is complicated by both the algorithms and the dynamic nature of the computations. In parallel the complexity of getting good performance is dependent upon the architecture and the application. Most attempts to address the complexity of AMR have lead to the development of library solutions, most have developed object-oriented libraries or frameworks. All attempts to date have made numerous and sometimes conflicting assumptions which make the evaluation of performance of AMR across different applications and architectures difficult or impracticable. The evaluation of different approaches can alternatively be accomplished through simulation of the different AMR processes. In this paper we outline our research work to simulate the processing of adaptive mesh refinement grids using a distributed array class library (P++). This paper presents a combined analytic and empirical approach, since details of the algorithms can be readily predicted (separated into specific phases), while the performance associated with the dynamic behavior must be studied empirically. The result, AMRSim, provides a simple way to develop bounds on the expected performance of AMR calculations subject to constraints given by the algorithms, frameworks, and architecture.

Libraries arise naturally from the increasing complexity of developing scientific applications, the optimization of libraries is just one type of high-performance optimization. Many complex applications areas can today be addressed by domain-specific object-oriented frameworks. Such object-oriented frameworks provide an effective compliment to an object-oriented language and effectively permit the design of what amount to essentially domain-specific languages. The optimization of such a domain-specific library/language combination however is particularly complicated due to the inability of the compiler to optimize the use of the libraries abstractions. The recognition of the use of object-oriented abstractions within user applications is a particularly difficult but important step in the optimization of how objects are used within expressions and statements. Such recognition entails more than just complex pattern matching. The approach presented within this paper uses specially built grammars to parse the C++ representation. The C++ representation is itself obtained using a modified version of the SAGE II C/C++ source code restructuring tool which is inturn based upon the Edison Design Group (EDG) C++ front-end. ROSETTA is a tool which automatically builds grammars and parsers from class definitions, associated parsers parse abstract syntax trees (ASTs) of lower level grammars into ASTs of higher level grammars.

Hardware performance counters are CPU registers that count data loads and stores, cache misses, and other events. Counter data can help programmers understand software performance. Although CPUs typically have multiple counters, each can monitor only one type of event at a time, and some counters can monitor only certain events. Therefore, some CPUs cannot concurrently monitor interesting combinations of events. Software multiplexing partly overcomes this limitation by using time sharing to monitor multiple events on one counter: However; counter multiplexing is harder to implement for multithreaded programs than for single-threaded ones because of certain difficulties in managing the length of the time slices. This paper describes a software library called MPX that overcomes these difficulties. MPX allows applications to gather hardware counter data concurrently for any combination of countable events. MPX data are typically within a few percent of counts recorded without multiplexing.

The Generalized System of Preferences (GSP) extends duty-free treatment to certain products that are imported from designated developing countries. The primary purpose of the program, which the United States and other industrial countries initiated in the 1970s, is to promote economic growth and development in these countries by stimulating their exports. The program was reauthorized by the 106th Congress, retroactively from July 1, 1999, through September 30, 2001. The 107th Congress will face the issue of whether to reauthorize GSP.
