Software Engineering for Self-Adaptive Systems: Assurances (Dagstuhl Seminar 13511)

Authors: Rogerio de Lemos, David Garlan, Carlo Ghezzi, and Holger Giese

Published in: Dagstuhl Reports, Volume 3, Issue 12 (2014)

Abstract
The important concern for modern software systems is to become more cost-effective, while being versatile, flexible, resilient, dependable, energy-efficient, customisable, configurable and self-optimising when reacting to run-time changes that may occur within the system itself, its environment or requirements. One of the most promising approaches to achieving such properties is to equip software systems with self-managing capabilities using self-adaptation mechanisms. Despite recent advances in this area, one key aspect of self-adaptive systems that remains to be tackled in depth is assurances, i.e., the provision of evidence that the system satisfies its stated functional and non-functional requirements during its operation in the presence of self-adaptation. The provision of assurances for self-adaptive systems is challenging since run-time changes introduce a high degree of uncertainty during their operation. In this seminar, we discussed the problem of assurances for self-adaptive systems from four different views: criteria for assurances, composition and decomposition of assurances, feedback loop and assurances, and perpetual provisioning of assurances.

Software Engineering for Self-Adaptive Systems: A second Research Roadmap

Abstract
The goal of this roadmap paper is to summarize the state of-the-art and identify research challenges when developing, deploying and managing self-adaptive software systems. Instead of dealing with a wide range of topics associated with the field, we focus on four essential topics of self-adaptation: design space for adaptive solutions, processes, from centralized to decentralized control, and practical run-time verification and validation. For each topic, we present an overview, suggest future directions, and focus on selected challenges. This paper complements and extends a previous roadmap on software engineering for self-adaptive systems published in 2009 covering a different set of topics, and reflecting in part on the previous paper. This roadmap is one of the many results of the Dagstuhl Seminar 10431 on Software Engineering for Self-Adaptive Systems, which took place in October 2010.

10431 Report – Software Engineering for Self-Adaptive Systems

Authors: Rogerio de Lemos, Holger Giese, Hausi Müller, and Mary Shaw

Published in: Dagstuhl Seminar Proceedings, Volume 10431, Software Engineering for Self-Adaptive Systems (2011)

Abstract
Softwares ability to adapt at run-time to changing user needs, system intrusions or faults, changing operational environment, and resource variability has been proposed as a means to cope with the complexity of todays software- intensive systems. Such self-adaptive systems can configure and reconfigure themselves, augment their functionality, continually optimise themselves, protect themselves, and re- cover themselves, while keeping most of their complexity hidden from the user and administrator. In this paper, we present research road map for software engineering of self- adaptive systems focusing on four views, which we identify as essential: design spaces, verification and validation, processes, and decentralisation.

06121 Report: Break Out Session on Guaranteed Execution

Authors: Calton Pu, Jim Johnson, Rogerio de Lemos, Andreas Reuter, David Taylor, and Irfan Zakiuddin

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

Abstract
The break out session discussed guaranteed properties during program execution. Using a workflow example application, we discussed several research topics that form part of the guaranteed properties, including declarative specifications, generation of workflow program, generation of invariant guards, automated failure analysis, automated repair, and automated reconfiguration of workflow.

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.
