Engineering Resilient Systems: Models, Methods and Tools (Dagstuhl Seminar 13022)

Authors: Maritta Heisel, Mohamed Kaaniche, Alexander Romanovsky, and Elena Troubitsyna

Published in: Dagstuhl Reports, Volume 3, Issue 1 (2013)

Abstract
Software-intensive systems are becoming widely used in such critical infrastructures as railway, air- and road traffic, power management, health care and banking. In spite of drastically increased complexity and need to operate in unpredictable volatile environment, high dependability remains a must for such systems. Resilience -- the ability to deliver services that can be justifiably trusted despite changes - is an evolution of the dependability concept. It adds several new dimensions to dependability concepts including adaptability to evolving requirements and proactive error prevention. To address these challenges we need novel models, methods and tools that enable explicit modeling of resilience aspects and reasoning about them. The Dagstuhl Seminar 13022 "Engineering Resilient Systems: Models, Methods and Tools" discussed the most promising techniques for achieving resilience both at the system design stage and at runtime. It brought together researchers from dependability, formal methods, fault tolerance and software engineering communities that promoted vivid cross-disciplinary discussions.

A Generic Framework for the Engineering of Self-Adaptive and Self-Organising Systems

Authors: Giovanna Di Marzo Serugendo, John Fitzgerald, Alexander Romanovsky, and Nicolas Guelfi

Published in: Dagstuhl Seminar Proceedings, Volume 8141, Organic Computing - Controlled Self-organization (2008)

Abstract
This paper provides a unifying view for the engineering of self-adaptive (SA) and self-organising (SO) systems. We first identify requirements for designing and building trustworthy self-adaptive and self-organising systems. Second, we propose a generic framework combining design-time and run-time features, which permit the definition and analysis at design-time of mechanisms that both ensure and constrain the run-time behaviour of an SA or SO system, thereby providing some assurance of its self-* capabilities. We show how this framework applies to both an SA and an SO system, and discuss several current proof-of-concept studies on the enabling technologies.

06121 Abstracts Collection – Atomicity: A Unifying Concept in Computer Science

Authors: Gerhard Weikum, Clifford B. Jones, David Lomet, and Alexander Romanovsky

Published in: Dagstuhl Seminar Proceedings, Volume 6121, Atomicity: A Unifying Concept in Computer Science (2006)

Abstract
From 19.03.06 to 24.03.06, the Dagstuhl Seminar 06121 ``Atomicity: A Unifying Concept in Computer Science'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

06121 Executive Summary – Atomicity: A Unifying Concept in Computer Science

Authors: Gerhard Weikum, Clifford B. Jones, David Lomet, and Alexander Romanovsky

Published in: Dagstuhl Seminar Proceedings, Volume 6121, Atomicity: A Unifying Concept in Computer Science (2006)

Abstract
This seminar was based on and continued the interaction of different computer-science communities that was begun in an earlier Dagstuhl seminar in April 2004. Both seminars have aimed at a deeper understanding of the fundamental concept of atomic actions and their roles in system design, execution, modeling, and correctness reasoning, and at fostering collaboration, synergies, and a unified perspective across largely separated research communities. Each of the two seminar brought together about 30 researchers and industrial practitioners from the four areas of database and transaction processing systems, fault tolerance and dependable systems, formal methods, and to smaller extent, hardware architecture and programming languages. The interpretations and roles of the atomicity concept(s) vary substantially across these communities. For example, the emphasis in database systems is on algorithms and implementation techniques for atomic transactions, whereas in dependable systems and formal methods atomicity is viewed as an intentionally imposed or postulated property of system components to simplify designs and increase dependability. Nevertheless, all four communities share the hope that it will eventually be possible to unify the different scientific viewpoints into more coherent foundations, system development principles, design methodologies, and usage guidelines.

The Atomic Manifesto: a Story in Four Quarks

Authors: Cliff Jones, David Lomet, Alexander Romanovsky, Gerhard Weikum, Alan Fekete, Marie-Claude Gaudel, Henry F. Korth, Rogerio de Lemos, Eliot Moss, Ravi Rajwar, Krithi Ramamritham, Brian Randell, and Luis Rodrigues

Published in: Dagstuhl Seminar Proceedings, Volume 4181, Atomicity in System Design and Execution (2004)

Abstract
This report summarizes the viewpoints and insights gathered in the Dagstuhl Seminar on Atomicity in System Design and Execution, which was attended by 32 people from four different scientific communities: database and transaction processing systems, fault tolerance and dependable systems, formal methods for system design and correctness reasoning, and hardware architecture and programming languages. Each community presents its position in interpreting the notion of atomicity and the existing state of the art, and each community identifies scientific challenges that should be addressed in future work. In addition, the report discusses common themes across communities and strategic research problems that require multiple communities to team up for a viable solution. The general theme of how to specify, implement, compose, and reason about extended and relaxed notions of atomicity is viewed as a key piece in coping with the pressing issue of building and maintaining highly dependable systems that comprise many components with complex interaction patterns.
