Abstract

Data replication is an important issue in computational grid environments where many data-intensive scientific applications require high-performance data accesses to remote storages. However, providing the consistent data replication service for computational grid environments is not an easy task because it requires a sophisticated technique to minimize I/O and communication latencies incurred during data copy steps to the remote clients. We have developed a replication architecture that is combined with data compression to reduce I/O and network overheads, with the help of data base. In this paper we describe the design and implementation of our replication architecture and present performance results on Linux clusters.
