Scalable message-logging techniques for effective fault tolerance in HPC applications
… techniques are checkpoint/restart and message-logging. The former is easier to implement and has become the de facto standard to make applications fault tolerant. It has, however, a high performance and energy cost during recovery. Message-logging, on the other hand, makes it possible …

Efficient Message Logging to Support Process Replicas in a Volunteer Computing Environment
… receive identical communication data streams. Logging to support redundancy can be the source of a significant overhead in time and storage. In this thesis we develop, implement and evaluate and compare pessimistic and optimistic logging schemes to support redundant communication. Pessimistic …

A Fault Tolerance Protocol for Fast Recovery
… restarts. We propose to combine the ideas of message logging and object based virtualization. We leverage the facts that message logging based protocols do not require all processors to rollback when one processor crashes and that object based virtualization allows work to be moved from one …

Heterogeneous and Mobile Recovery
… status of current execution. A receiver-based message logging algorithm has been implemented and evaluated on both wired and wireless networks. The experimental results show that the adaptive protocol incurs low overhead, avoids unnecessary checkpointing, and reduces failure-free execution time.
