Abstract:

The research sponsored by this contract has produced the following results 1 A model for recovery using message logging and checkpointing, resulting in a major theorem establishing the uniqueness of a maximum recoverable system state 2 An implementation and a performance evaluation of sender-based message logging 3 A batch and an incremental algorithm for optimistic recovery, and an implementation and a performance evaluation of optimistic recovery 4 Preliminary results in extending these methods to nondeterministic processes and 5 A new definition of distributed breakpoint, called causal distributed breakpoint.
