``Minimizing Timestamp Size for Completely Asynchronous Optimistic
Recovery with Minimal Rollback''
15th IEEE Symposium on Reliable Distributed Systems.
October 1996.
Abstract
Basing rollback recovery on optimistic message logging and replay
avoids the need for synchronization between processes during
failure-free execution. Some previous research has also attempted to
reduce the need for synchronization during recovery, but these
protocols have suffered from three problems: not eliminating all
synchronization during recovery, not minimizing rollback, or
providing these properties but requiring large timestamps. This
paper makes two contributions: we present a new rollback
recovery protocol, based on our previous work, that provides these
properties (asynchronous recovery, minimal rollback) while reducing
the timestamp size; and we prove that no protocol can provide these
properties and have asymptotically smaller timestamps.
