Performance Modeling and Analysis for Centralized Resource Scheduling in Metropolitan-Area Grids

摘要

Metropolitan-Area Grid (MAG) normally deals with a more limited computation and data-intensive problems on geographically distributed and smaller range resources. Therefore, in a MAG, resource scheduling is distinguished from other Grid. Current research on performance evaluation of resource scheduling in MAG is based on simulation techniques, which can only consider a limited range of scenarios. In this paper, we propose a centralized resource scheduling model in a MAG and give a formal framework via Stochastic Process Algebras (SPA) to deal with this problem. Within this framework, we model and analyze the performance of resource scheduling, allowing for a wide variety of job and data scheduling algorithms. Moreover, we can evaluate the combined effectiveness of job and data scheduling algorithms, rather than study them separately.
