Performance analysis of Grid applications in the ASKALON environment

In this paper we describe the approach taken by the ASKALON Grid application development and computing environment for scalability and overhead analysis of scientific applications in the Austrian Grid. We present a technique imported from parallel processing for overhead and scalability analysis of Grid applications based on speedup and efficiency metrics required primarily for tuning the middleware services and improving the executions. We present experimental results that validate our techniques for five real-world applications in the Austrian Grid environment.
