Parallel processing is now becoming a household word among computer researchers and designers. This work contains 29 contributions from leading experts in the field attending the 1992 NATUG conference.

For the second time the International Workshop on Responsive Com puter Systems has brought together a group of international experts from the fields of real-time computing, distributed computing, and fault tolerant systems. The two day workshop met at the splendid facilities at the KDD Research and Development Laboratories at Kamifukuoka, Saitama, in Japan on October 1 and 2, 1992. The program included a keynote address, a panel discussion and, in addition to the opening and closing session, six sessions of submitted presentations. The keynote address "The Concepts and Technologies of Depend able and Real-time Computer Systems for Shinkansen Train Control" covered the architecture of the computer control system behind a very responsive, i. e. , timely and reliable, transport system-the Shinkansen Train. It has been fascinating to listen to the operational experience with a large fault-tolerant computer application. "What are the Key Paradigms in the Integration of Timeliness and Reliability?" was the topic of the lively panel discussion. Once again the pro's and con's of the time-triggered versus the event-triggered paradigm in the design of a real-time systems were discussed. The eighteen submitted presentations covered diverse topics about important issues in the design of responsive systems and a session on progress reports about leading edge research projects. Lively discussions characterized both days of the meeting. This volume contains the revised presentations that incorporate some of the discussions that occurred during the meeting.

This book originates from the 5th LOMAPS Workshop on Analysis and Verification of Multiple-Agent Languages, held in Stockholm, Sweden, in June 1996. LOMAPS is an ESPRIT project devoted to program analysis and verification techniques applicable to emerging multi-paradigm programming languages. The volume presents 14 revised full papers selected from the workshop submissions together with 4 invited contributions; also included is an introductory overview surveying the state of the art in the area and putting the contributions into this context.

Formality is becoming accepted as essential in the development of complex systems such as multi-layer communications protocols and distributed systems. Formality is mandatory for mathematical verification, a procedure being imposed on safety-critical system development. Standard documents are also becoming increasingly formalised in order to capture notions precisely and unambiguously. This FORTE '91 proceedings volume has focussed on the standardised languages SDL, Estelle and LOTOS while, as with earlier conferences, remaining open to other notations and techniques, thus encouraging the continuous evolution of formal techniques. This useful volume contains 29 submitted papers, three invited papers, four industry reports, and four tool reports organised to correspond with the conference sessions.

This volume contains the proceedings of the Fifth International Conference on Coordination Models and Languages (Coordination 2002), held in York, UK, 8–11 April 2002. Coordination models and languages close the conceptual gap - tween the cooperation model used by the constituent parts of an application and the lower-level communication model used in its implementation. Coordinati- based methods provide a clean separation between individual software com- nents and their interactions within their overall software organization. This se- ration, together with the higher-level abstractions o?ered by coordination models and languages, improve software productivity, enhance maintainability, advocate modularity, promote reusability, and lead to software organizations and arc- tectures that are more tractable and more amenable to veri?cation and global analysis. Coordination is relevant in design, development, debugging, maintenance, and reuse of all complex concurrent and distributed systems. Speci?cally, - ordination becomes paramount in the context of open systems, systems with mobile entities, and dynamically re-con?gurable evolving systems. Moreover, - ordination models and languages focus on such key issues in Component Based Software Engineering as speci?cation, interaction, and dynamic composition of components.

Advances in Parallel Computing series presents the theory and use of of parallel computer systems, including vector, pipeline, array, fifth and future generation computers and neural computers. This volume features original research work, as well as accounts on practical experience with and techniques for the use of parallel computers.
