  title: PDS: A Performance Database Server
  by: Michael W. Berry, Jack J. Dongarra, and Brian H. LaRose
  for: The process of gathering, archiving, and distributing computer , benchmark data is a cumbersome task usually performed by computer , users and vendors with little coordination. Most important, , there is no publicly-available central depository of performance data , for all ranges of machines from personal computers to supercomputers. , We present an Internet-accessible performance database server (PDS) which , can be used to extract current benchmark data and literature. As , an extension to the X-Windows-based user interface (Xnetlib) , to the Netlib archival system, PDS provides an on-line catalog of , public-domain computer benchmarks such as the LINPACK Benchmark, , Perfect Benchmarks, and the NAS Parallel Benchmarks. PDS does not , reformat or present the benchmark data in any way that conflicts with the , original methodology of any particular benchmark; it is thereby , devoid of any subjective interpretations of machine performance. , We feel that all branches (research laboratories, academia, and industry) of the , general computing community can use this facility to archive performance metrics , and make them readily available to the public. PDS can provide a more , manageable approach to the development and support of a large , dynamic database of published performance metrics.

  title: Distributed Information Management in the National HPCC , Software Exchange
  by: Shirley Browne, Jack Dongarra, Geoffrey C. Fox, Ken Hawick, , Ken Kennedy, Rick Stevens, Robert Olson, Tom Rowan
  for: The National HPCC Software Exchange , is a collaborative effort by member institutions of the , Center for Research on Parallel Computation , to provide network access to HPCC-related software, documents, , and data. , Challenges for the NHSE include identifying, organizing, filtering, , and indexing the rapidly growing wealth of relevant information , available on the Web. , The large quantity of information necessitates performing these , tasks using automatic techniques, many of which make use of parallel , and distribution computation, but human intervention is needed for , intelligent abstracting, , analysis, and critical review tasks. Thus, major goals of , NHSE research are to find the right mix of , manual and automated techniques, and to leverage the results of , manual efforts to the maximum extent possible. This paper describes , our current information gathering and , processing techniques, as well as our future plans for integrating , the manual and automated approaches. , The NHSE home page is accessible at http://www.netlib.org/nhse/.

  title: Repository Mirroring
  by: Eric Grosse
  for: Distributed administration of network repositories demands , a low overhead procedure for cooperating repositories around the , world to ensure they hold identical contents. Netlib has , adopted some refinements on the widespread scheme of anonymous , ftp and ls-lR. Checksum files and a two small C programs give , an easily maintained system that copes with communication , breakdowns and subtle changes in repository contents. The , packaging of these C programs inside a shell pipeline provides , an explicit command stream that can readily be checked before , execution. Protecting files, keeping logs, and so forth becomes , effortless and reliable. The same tools, applied on a smaller , scale, allow more people to participate in the editorial work of , maintaining a high-quality repository, by eliminating the need , for directly manipulating files at remote sites.

  title: Software Reuse in High Performance Computing
  by: Shirley Browne, Jack Dongarra, Geoffrey Fox, Ken Hawick, Tom Rowan
  for: Although high performance computing architectures in the form of , distributed memory multiprocessors have become available, these , machines have not achieved widespread use outside of academic , research environments. The slowness in adopting high performance , architectures appears to be caused by the difficulty and cost of , programming applications to run on these machines. Economical use , of high performance computing and subsequent adoption by industry , will only occur if widespread reuse of application code can be , achieved. To accomplish this goal, , we propose strategies for achieving reuse of application , code across different machine architectures and for using portable , reusable components as building blocks for applications.

  title: Means of Achieving Cross-Program Focus, Coordination, , and Technology Transfer
  by: Shirley Browne, Jack Dongarra, Geoffrey Fox, and Ken Kennedy
  for: This paper is in response to the National Science and Technology , Council (NSTC) Committee on Information and Communications R\&D , (CIC) call for white papers on the CIC's Strategic Implementation , Plan for America in the Age of Information. , We agree with the identification of strategic focus areas and , the need for efficient coordination of activities. , However, the Strategic Plan provides only a high level description , of how the focusing and coordination will be carried out , through the use of information technology. , The Strategic Plan emphasizes the importance of accelerating , the maturation and broad deployment of technologies, but again , nowhere is it spelled out how this acceleration will be achieved. , We propose the use of domain-specific modeling of complex , hardware and software systems, coupled with formation of , domain-specific but interoperable resource and knowledge bases for , achieving the needed focus, coordination, and technology transfer. , We further propose the selection of a particular strategic , focus area, namely high performance/scalable systems, and a particular , application category, namely high performance applications, in , which to initially investigate the effectiveness of the proposed , approach. If this initial focus is successful, , the lessons learned and the methods and tools produced , will be applicable to the other focus areas.

  title: A Scalable File Replication Scheme for the World Wide Web
  by: Keith Moore, Jason Cox, Stan Green, and Reed Wade
  for: The World Wide Web has reached the point where many popular , file servers are overloaded, resulting in degradation or unavailability , of service. Users are also often separated over a small-bandwidth , pipe from a file server they need to access, resulting in poor , response time. The Bulk File Distribution (BFD) system described , in this paper aims to alleviate these problems by providing , mechanisms for registering and looking up alternative locations for , replicated files. The system also includes authentication and , integrity checking mechanisms. Unlike other proposed name , resolution systems, BFD provides a straightforward consistency , model for updates through the use of an intermediate file handle that , unambiguously identifies a particular sequence of bytes. We , describe a strategy for a gradual transition from using URLs to , using location-independent names which achieves the benefits of , replication while retaining the familiar URL syntax. We also , describe a service called SONAR that is intended to assist client , programs in choosing among alternative locations for a file, based , on a proximity measure. Finally, we describe a prototype , implementation of the BFD system.

  title: Software Repository Interoperability
  by: Shirley Browne, Jack Dongarra, Kay Hohn, and Tim Niesen
  for: A number of academic, commercial, and government , software repositories currently exist that provide access to , software packages, reusable software components, and related documents, , either via the Internet or via intra-organizational intranets. , It is highly desirable, both for user convenience and savings in , duplication of effort, that these repositories interoperate. , This paper describes interoperability standards that have , already been developed as well as those under development by the , Reuse Library Interoperability Group (RIG). These standards include , a data model for a common semantics for describing software resources, , as well as frameworks for describing software certification policies , and intellectual property rights. The National HPCC Software Exchange , (NHSE) is described as an example of an organization that is achieving , interoperation between government and academic HPCC software , repositories, in part through adoption of RIG standards.

  title: Reuse Library Interoperability and the World Wide Web
  by: Shirley Browne and James Moore
  for: The Reuse Library Interoperability Group (RIG) was formed in 1991 , for the purpose of drafting standards enabling the interoperation , of software reuse libraries. At that time, prevailing wisdom , among many reuse library operators was that each should be a , stand-along operation. Many operators saw a need for only a single , library, their own, and most strived to provide the most general , possible services to appeal to a broad community of users. , The ASSET program, initiated byt he Advanced Research Projects Agency , STARS program, was the first to make the claim that it should , properly by one part of a network of interoperating libraries. , Shortly thereafter, the RIG was formed, initially , as a collaboration between the STARS program and the Air Force , RAASP program, but growing within six months to a self-sustaining , cooperation among twelve chartering organizations. , The RIG has grown to include over twenty members from government, , industry, and academic reuse libraries. It has produced a number , of technical reports and proposed interoperability standards, some , of which are described in this report.
