High-performance computing refers to the use of advanced computing technologies to solve highly complex problems in the shortest possible time. The federal High Performance Computing and Communications Initiative of the Advanced Research Project Agency (ARPA) attempts to accelerate availability and use of high performance computers and networks. The House Armed Services Committee asked the General Accounting Office (GAO) to assess this program, particularly the agency's distribution of advanced computers to research sites, its interaction with the research community, and the balance between hardware and software. Interviews with agency and industry representatives and a review of documents were conducted. Results indicate that the ARPA has fostered significant advances, but with several shortcomings. Placing of new computers has focused on just a few machines. Limited interactions with the technical community may be hindering progress toward ambitious program goals. Much progress has been made in hardware development, but software remains too primitive to make massively parallel processing systems useful. Recommendations for improvement are presented. Four appendixes provide details about methodology, placement of machines, and project selection, and list contributors to the report. Five tables contain study findings, and two figures illustrate computer applications and product selection. (SLD)

The purpose of the hearing transcribed in this document was to obtain the views of representatives of network user and provider communities regarding the path the National Science Foundation (NSF) is taking for recompetition of the NSFNET computer network. In particular the committee was interested in the consistency of the evolution of NSFNET with the goals and characteristics of the National Research and Education Network specified in the High Performance Computing Act. Another purpose of the hearing was to explore possible legislation that would expand the program into additional applications for broad public benefit, including education, teacher training, manufacturing technologies, medical imaging, and the creation of standards for the storage of data in digital libraries. Persons who offered testimony and prepared statements were: (1) Robert C. Heterick, Jr., EDUCOM; (2) Thomas J. Tauke, NYNEX; (3) Kenneth J. Klingenstein, University of Colorado at Boulder and Federation of American Research Networks; (4) Mitchell Kapor, Electronic Frontier Foundation; (5) Kenneth R. Kay, Computer Systems Policy Project; (6) Michael McDonald, Communications and Computer Applications in Public Health; (7) Sara A. Parker, Pennsylvania State libraries and representing the American Library Association; and (8) Charlie Bender, Coalition of Academic Supercomputer Centers. (KRN)

With about 200,000 entries, StarBriefs Plus represents the most comprehensive and accurately validated collection of abbreviations, acronyms, contractions and symbols within astronomy, related space sciences and other related fields. As such, this invaluable reference source (and its companion volume, StarGuides Plus) should be on the reference shelf of every library, organization or individual with any interest in these areas. Besides astronomy and associated space sciences, related fields such as aeronautics, aeronomy, astronautics, atmospheric sciences, chemistry, communications, computer sciences, data processing, education, electronics, engineering, energetics, environment, geodesy, geophysics, information handling, management, mathematics, meteorology, optics, physics, remote sensing, and so on, are also covered when justified. Terms in common use and/or of general interest have also been included where appropriate.

High-performance computing (HPC) describes the use of connected computing units to perform complex tasks. It relies on parallelization techniques and algorithms to synchronize these disparate units in order to perform faster than a single processor could, alone. Used in industries from medicine and research to military and higher education, this method of computing allows for users to complete complex data-intensive tasks. This field has undergone many changes over the past decade, and will continue to grow in popularity in the coming years. Innovative Research Applications in Next-Generation High Performance Computing aims to address the future challenges, advances, and applications of HPC and related technologies. As the need for such processors increases, so does the importance of developing new ways to optimize the performance of these supercomputers. This timely publication provides comprehensive information for researchers, students in ICT, program developers, military and government organizations, and business professionals.

In Perform or Else Jon McKenzie brilliantly explores the relationship between cultural, organisational, and technological performance.
