Message Logging: Pessimistic, Optimistic, and Causal
Message logging protocols are an integral part of a technique for implementing processes that can recover from crash failures. All message logging protocols require that, when recovery is complete, there be no orphan processes, which are surviving processes whose states are inconsistent with the recovered state of a crashed process. We give a precise speciication of the consistency property \no...

Message-logging protocols are an integral part of a popular technique for implementing processes that can recover from crash failures. All message-logging protocols require that, when recovery is complete, there be no orphan processes , which are surviving processes whose states are inconsistent with the recovered state of a crashed process. We give a precise speci cation of the consistency pro...
متن کاملImproving Message Logging Protocols Scalability through Distributed Event Logging
Message logging is an attractive solution to provide fault tolerance for message passing applications because it is more scalable than coordinated checkpointing. Sender-based message logging is a well known optimization that allows to save messages payload in the sender memory and so only the events corresponding to message receptions have to be logged reliably using an event logger. In existin...

متن کاملSender-Based Message Logging
Sender based message logging is a new low overhead mech anism for providing transparent fault tolerance in dis tributed systems It di ers from conventional message log ging mechanisms in that each message is logged in volatile memory on the machine from which the message is sent Keeping the message log in the sender s local memory allows us to recover from a single failure at a time with out th...
