A distributed data storage architecture for event processing by using the globus grid toolkit

Abstract

In this paper we discuss a Grid-based Event Processing System (GEPS). Data intensive problems broadly exist in many scientific computational areas; usually their needs for super storage and computing capacities are difficult to be fully satisfied. Meanwhile the Globus Toolkit has become the de facto standard of building high performance distributed computing environments. Event processing and filtering is a kind of data intensive problem in high-energy physics area. Using the Globus grid toolkit, we have constructed the GEPS system, which provides web-based access to grid computing environments for event processing. Performance result indicates that event processing and filtering can be effectively implemented on GEPS.
