Transaction state broadcast method using a two-stage multicast in a multiple processor cluster having a sender time of life marker used by receiver to request resynchronization

摘要

In a multiple processing system comprising multiple communicatively interconnected nodes, each node having one or more processor units, multicast messages sent by a sender node will contain information that allows intended receiver nodes to check and determine the possibility that earlier-sent multicast messages from the sender node were not received by the receiver node.
