This paper analyzes the execution overhead inherent in the conversation scheme, which is a scheme for realizing fault-tolerant cooperating processes free of the domino effect. Multiprocessor/multicomputer systems capable of parallel execution of conversation components are considered and a queueing network model of such systems is adopted. Based on the queueing model, various performance indicators such as system throughput, average number of processors idling inside a conversation due to the synchronization required, and average time spent in the conversation, have been evaluated numerically for several application environments. The numeric results are discussed and from there several essential performance characteristics of the conversation scheme are derived.
