Technological advances are revolutionizing computers and networks to supportdigital video and audio, leading to new design spaces in computer systems and applications. Under the surface of exciting multimedia technologies liesa mine of research problems. This volume presents the proceedings of an international workshop which brought together the leading researchers in allaspects of multimedia computing, communication, storage, and applications. The field of multimedia has witnessed an explosive growth in the last few years and the selection of papers for this workshop was extremely competitive. The volume contains 26 full papers and 14 short papers selected from 128 contributions, organized into parts on: network and operating system support for multimedia; multimedia on-demand services; media synchronization; distributed multimedia systems; network andoperating system support for multimedia; multimedia models, frameworks, and document architectures; and multimedia workstations and platforms.

This volume contains the proceedings of the fifth International Workshop on Distributed Algorithms (WDAG '91) held in Delphi, Greece, in October 1991. The workshop provided a forum for researchers and others interested in distributed algorithms, communication networks, and decentralized systems. The aim was to present recent research results, explore directions for future research, and identify common fundamental techniques that serve as building blocks in many distributed algorithms. The volume contains 23 papers selected by the Program Committee from about fifty extended abstracts on the basis of perceived originality and quality and on thematic appropriateness and topical balance. The workshop was organizedby the Computer Technology Institute of Patras University, Greece.

In general, distributed systems can be classified into Distributed File Systems (DFS) and Distributed Operating Systems (DOS). The survey which follows distinguishes be tween DFS approaches in Chapters 2-3, and DOS approaches in Chapters 4-5. Within DFS and DOS, I further distinguish "traditional" and object-oriented approaches. A traditional approach is one where processes are the active components in the systems and where the name space is hierarchically organized. In a centralized environment, UNIX would be a good example of a traditional approach. On the other hand, an object-oriented approach deals with objects in which all information is encapsulated. Some systems of importance do not fit into the DFS/DOS classification. I call these systems "closely related" and put them into Chapter 6. Chapter 7 contains a table of comparison. This table gives a lucid overview summarizing the information provided and allowing for quick access. The last chapter is added for the sake of completeness. It contains very brief descriptions of other related systems. These systems are of minor interest or do not provide transparency at all. Sometimes I had to assign a system to this chapter simply for lack of adequate information about it."

This special volume contains the Proceedings of a Workshop on "Parallel Algorithms and Transputers for Optimization" which was held at the University of Siegen, on November 9, 1990. The purpose of the Workshop was to bring together those doing research on 2.lgorithms for parallel and distributed optimization and those representatives from industry and business who have an increasing demand for computing power and who may be the potential users of nonsequential approaches. In contrast to many other conferences, especially North-American, on parallel processing and supercomputers the main focus of the contributions and discussion was "problem oriented". This view reflects the following philosophy: How can the existing computing infrastructure (PC's, workstations, local area networks) of an institution or a company be used for parallel and/or distributed problem solution in optimization. This volume of the LECfURE NOTES ON ECONOMICS AND MA THEMA TICAL SYSTEMS contains most of the papers presented at the workshop, plus some additional invited papers covering other important topics related to this workshop. The papers appear here grouped according to four general areas. (1) Solution of optimization problems using massive parallel systems (data parallelism). The authors of these papers are: Lootsma; Gehne. (II) Solution of optimization problems using coarse-grained parallel approaches on multiprocessor systems (control parallelism). The authors of these papers are: Bierwirth, Mattfeld, and Stoppler; Schwartz; Boden, Gehne, and Grauer; and Taudes and Netousek.

The market for information technology products is rapidly changing from a manufactur er-driven market where new products were determined by the evolution of technology, to a user-driven market where users buy only products corresponding exactly to their needs and where competition is very strong. Confronted with this market situation, hardware and software producers are being obliged to adopt new strategies, and to make a large number of products available on the market in response to a variety of different needs. As a result of the multiplicity of choice available, the design of an office system which corresponds precisely to user needs is becoming an increasingly complex task. With exactly this in mind, the Commission, as early as 1985, invited submissions of projects aiming at the development of such adequate tools in its Call for Proposals for the ESPRIT Programme, in order to assist companies in the design of their office systems. This topic was recognised as being of strategic importance, considering the low level of penetration of Information Technology in European enterprises compared to the United States and Japan. Following this strategy, the project TODOS was selected and launched. This project has successfully developed tools and methods for the definition of the functional specifi cation of the office system, as well as the system architecture and user interface -results which can be of great interest for the IT community at large.

This volume contains the proceedings of the 4th International Workshop on Distributed Algorithms, held near Bari, Italy, September 24-26, 1990. The workshop was a forum for researchers, students and other interested persons to discuss recent results and trends in the design and analysis of distributed algorithms for communication networks and decentralized systems. The volume includes all 28 papers presented at the workshop, covering current research in such aspects of distributed algorithm design as distributed combinatorial algorithms, distributed algorithms on graphs, distributed algorithms for new types of decentralized systems, distributed data structures, synchronization and load-balancing, distributed algorithms for control and communication, design and verification of network protocols, routing algorithms, fail-safe and fault-tolerant distributed algorithms, distributed database techniques, algorithms for transaction management and replica control, and other related topics.

Architectural and hardware advances in computing design are occurring at an ever quickening rate, but it is the operating system that masters the complexity of these new computing devices to make them useful tools. Operating systems can make the difference between an interesting architecture and a useful computing environment. As more complex computational structures and more powerful communication technologies become available, we are faced with the need to develop new generations of operating systems to harness their power. This volume presents the proceedings of an international workshop intended to plot a course for design and development work on operating systems over the coming decade that was held in Dagstuhl Castle, Germany, in July 1991. Eight sessions covered: - Size, scalability and distribution in future operating systems, - The impact of future trends in hardware and communication technology, - Integrating heterogeneous operating systems, - Trends in real-time operating systems, - Fault tolerance support in futute operating systems, - Security and protection support in future operating systems, - The next generation of operating systems, - Supporting mulitmedia applications in distributed systems.

During the last few years, computers have evolved from pure number crunching machines to "intelligent" problem solving tools. Increasing effort has been spent on the investigation of new approaches and the application of solutions to real world problems. In this way, exciting new techniques have evolved providing support for an increasing number of technical and economical aspects. Applications range from the design and development of ultra highly integrated circuits to totally new man-machine interfaces, from software engineering tools to fault diagnosis systems, from decision support to even the analysis of unemployment. Following a first joint workshop on Advanced Information Processing held in July 1988 at the Institute for Problems of Informatics of the USSR Academy of Sciences (IPIAN) at Moscow, this was the second time that scientists and researchers from the USSR Academy of Sciences and Siemens AG, Corporate Research and Development, exchanged results and discussed recent advances in the field of applied computer sciences. Initiated by Prof. Dr. I. Mizin, Corresponding Member of the USSR Academy of Sciences and Director of IPIAN, and Prof. Dr. H. Schwartzel, Vice President of the Siemens AG and Head of the Applied Computer Science & Software Department, a joint symposium was arranged at the USSR Academy of Sciences in Moscow on June 5th and 6th 1990. The meetings on Information Processing and Software and Systems Design Automation provided a basis both for presentations of ongoing research and for discussions about specific problems.

The purpose of this workshop was to provide a general forum for distributed systems researchers. Special em- phasis was placed on research activities in distributed operating systems and management of distributed sys- stems. This volume includes a selection of the papers presented at the workshop. They focus on the illustration of existing concepts and solutions in distributed systems research and development, exemplified by case study analyses of various projects. The annex contains the position papers prepared for the panel discussions at the workshop.

Die Leistung von Computersystemen ist die ausschlaggebende Groe fur ihren Einsatz. Zur Messung der Leistung wird sehr oft das Benchmark-Verfahren als Standard-Tool eingesetzt, obwohl allgemein bekannt ist, dass die entsprechenden Ergebnisse nur eine sehr beschrankte Aussagekraft haben - dafur spricht naturlich ihre starke Orientierung an der Praxis. Modellbildende Techniken werden haufig zu Recht als "Mathematik-lastig" empfunden und suggerieren zudem eine Genauigkeit jenseits der Realitat. Dabei liegt es auf der Hand, dass beide Standpunkte sich erganzen und zusammen eine wesentlich bessere Messung, Analyse und Bewertung gestatten. Anhand dieser Konzeption erlautert der Autor bessere Methoden zur Leistungsbewertung von Computersystemen.

Well suited to medium-scale general purpose computing, the Unix time sharing operating system is deservedly popular with academic institutions, research laboratories, and commercial establishments alike. Its user com munity, until recently a brotherhood of experienced computer profes sionals, it now attracting many people concerned with computer appli cations rather than the computer systems themselves. This book is intended for that new audience, people who have never encountered the Unix system before but who do have some acquaintance with computing. While helping beginning users get started is the primary aim of this book, it is also intended to serve as a handy reference subsequently. However, it is not designed to replace the definitive Unix system docu mentation. Unix operating systems now installed in computing centers, offices, and personal computers come in three related but distinct breeds: Seventh Edition Unix, Berkeley 4.2 BSD, and System V. These differ from each other in details, even though their family resemblance is strong. This book emphasizes System V, while paying heed to its two popular cousins. It also includes a few facilities in wide use, but not included in the normal system releases. Individual details, of course, must be found in the manuals supplied with each system."

This volume contains the proceedings of an international workshop on "Experiences with Distributed Systems" held September 28-30, 1987, at the University of Kaiserslautern. The workshop was jointly sponsored and organized by the Sonderforschungsbereich 124 "VSLI-Entwurfsmethoden und ParallelitAt" and the European Network Center (ENC) of the IBM Corporation, Heidelberg. The objective of the workshop was to bring together researchers who had gathered substantial experience with the implementation of distributed systems. The emphasis was put on the exchange of (good and bad) experiences with existing concepts in distributed system design rather than presenting new ideas. Participation in the workshop was by invitation only. The presentations can be roughly categorized as reports on a specific project or reports on experiences with a certain topic accumulated through several projects. Other lectures treated general topics such as fault tolerance, design principles for distributed languages and systems, and distributed databases.

This volume contains revised versions of presentations at the International Workshop on Analogical and Inductive Inference (AII '86) held in Wendisch-Rietz, GDR, October 16-10, 1986. Inductive inference and analogical reasoning are two basic approaches to learning algorithms. Both allow for exciting problems and promising concepts of invoking deeper mathematical results for considerable advances in intelligent software systems. Hence analogical and inductive inference may be understood as a firm mathematical basis for a large variety of problems in artificial intelligence. While the papers on inductive inference contain technical results and reflect the state of the art of this well-developed mathematical theory, those devoted to analogical reasoning reflect the ongoing process of developing the basic concepts of the approach. The workshop thus contributes significantly to the advancement of this field.

This volume contains the proceedings of the Second International Conference on Rewriting Techniques and Applications, "RTA 87," held in Bordeaux, France, May 1987.
