A research team led by SRI International has completed a 1.5 year period of work in adaptive, distributed, fault-resistant systems. This research has been motivated by the increasingly complex and dynamic nature of working environments for modern systems, especially distributed, real-time systems. Operating conditions in such environments vary greatly in the types and distributions of faults and input data, in user requirements in changing service situations, and in possible losses of computing resources. The traditional approach---applying given resources in a fixed system configuration to meet worst-case operating conditions--- is becoming less tenable. Adaptive systems can track changes in the environment by modifying the way computing resources are organized and utilized. The goal of the research was to establish a foundation for a general methodology of design for adaptive, distributed, real-time, fault-resistant systems. This report presents a general theory and architecture, a t...
