Abstract

Today's scientific simulations often generate huge amounts of data for data archival, data analysis, and visualization. These data are stored in high-performance distributed storages that consist of a network-oriented computing environment. In such a computing environment, one of the major issues affecting in achieving substantial I/O performance and scalability is to build an efficient locking protocol. In this paper, we present a distributed locking protocol that enables multiple client nodes to simultaneously write their data to distinct data portions of a file, while providing the consistent view of client cached data, and conclude with an evaluation of the performance of our locking protocol on a Linux cluster.
