Abstract:Global predicate evaluation is a fundamental problem in distributed systems. This paper views it from a different perspective, namely that of the Signals and Systems area of Electrical Engineering. It adapts a signal processing approach to address this problem in the context of monitoring of 'health' of a software system. The global state of the system is viewed as a 'state' signal which evolves over time. The distributed processes are assumed to possess roughly synchronized clocks. The states of individual pr… Show more
