Abstract

An efficient fault-tolerant protocol for computing the processor membership of a dynamically-evolving distributed processor system is proposed. The proposed protocol guarantees finite processor failure and join detection delays, provides all correctly functioning processors with identical membership information a any local clock time, is tolerant of any number of likely faults except network partitioning, and has minimal run-time overhead when no faults occur. In addition, while assuming no shared storage among processors, the protocol scales well when the number of processors of a system increases.
