The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Coordinated Atomic actions (CA actions) provide a scheme for coordinating complex concurrent activities and supporting error recovery between multiple interacting objects in a distributed object-oriented system. In this paper we show how CA actions can be applied to two different areas: safety-critical systems and fault-tolerant parallel systems. We have used a Production Cell case study to show how we can use CA actions to control a safety-critical system, where safety requirements play a fundamental role, and we have used an example based on the GAMMA paradigm to demonstrate how CA actions can be used to add fault tolerance to a parallel computation model. We discuss how CA actions provide these systems with dependability features, and describe our Java framework for constructing CA actions.
