Simulation of hierarchical real-time task scheduling algorithms using DGridSim

Abstract

Real-time Data Grid applications are emerging in many disciplines of science and engineering. In order to run these applications while meeting the real-time constraints associated with them, the Data Grid infrastructure should be designed to respect these constraints and allocate its computing, networking, storage, and the other resources accordingly. In this study, a process oriented and discrete-event driven all-in-one Data Grid simulator (DGridSim) supporting real-time operation through advance reservation mechanism is used to test the real time performance of a task scheduling algorithm
