dc.description.abstractThis paper considers quorum-replicated, multi-writer, multi-reader (MWMR) implementations of survivable atomic registers in a distributed message-passing system with processors prone to failures. Previous implementations in such settings invariably required two rounds of communication between readers/writers and replica owners. Hence the question arises whether it is possible to have single round read and/or write operations in this setting. We thus devise an algorithm, called Sfw, that exploits a new technique called server side ordering (SSO), which -unlike previous approaches- places partial responsibility for the ordering of write operations on the replica owners (the servers). With SSO, fast write operations are introduced for the very first time in the MWMR setting. We prove that our algorithm preserves atomicity in all permissible executions. While algorithm SFW shows that in principle fast writes are possible, we also show that under certain conditions the MWMR model imposes inherent limitations on any quorum-based fast write implementation of a safe read/write register and potentially even restricts the number of writer participants in the system. In this case our algorithm achieves near optimal efficiency. © 2009 Springer-Verlag.en
