CAUSAL RELATIONS AND CAUSAL ORDERING GUARANTEEING ALGORITHM
分布进程间通信合作因果关系及因果序的保证

This paper introduces the causal relations between events among communicating and cooperating processes in distributed systems. Based on the viewpoint that more than one task may progress among a group of cooperating processes and the tasks may not relate with each other, the authors propose the concept of event class. Furthermore, they propose a causal ordering guaranteeing algorithm using the event class concept.
