Abstract
Data replication is a critical issue in distributed computing where a large amount of data sets are frequently shared among geographically distributed scientists. The usual way of managing consistent data replicas between distributed sites is to periodically update the remotely located data replicas. However, this method doesn’t guarantee the replica consistency in such a case that remote clients who retain the replicas irregularly update or modify their replicas. In this paper, we introduce two kinds of data replication techniques, called owner-initiated data replication and client-initiated data replication, that are developed to support data replica consistency without requiring any special file system-level locking functions. Also, we present performance results on Linux clusters located at Sejong University.
