WebFeb 1, 1993 · A taxonomy for processor and memory techniques based on the memory hierarchy is presented, which provides a basis for understanding subtle differences among the various schemes. Several hardware-based techniques that support checkpoint and rollback recovery are presented. The focus is on hardware schemes for uniprocessors, … WebAsynchronous Checkpointing • Construct a recovery line for a given failure – Rollback failed process to its previous checkpoint – If there is an orphan message, require rollback …

A … WebCheckpointing and Rollback-Recovery. Each process in the system periodically takes a checkpoint to reduce the amount of recomputation in case of a system failure. A checkpoint includes the intermediate state of the process, the current vector clock, the current content of the diff structure and other information required for memory consistency.

Indeed, it is necessary to reconsider these protocols to adapt them to fit for the mobile context.
