Simulation of real-time Data Grid systems via DGridSim simulator

Abstract

In this study, DGridSim simulator will be introduced and some example simulation results will be presented. DGridSim can simulate four different Data Grid system organizations. Furthermore, for every system organization, the simulation of job scheduling, data dissemination, and data replication algorithms are supported, while all related system resources including computing, data storage, and network are reserved in advance in order to meet deadlines associated with jobs. DGridSim simulator is designed to be modular and easily extensible.
