GridSim Need for a repeatable & controllable Grid environment. o o
Evaluate different scenarios Inherent heterogeneity & complexity of a real Grid environment
Solution – use simulation – GridSim o
Provides deterministic modeling & simulation of resources and applications to evaluate scheduling strategies
o
Builds on SimJava that uses discrete-event simulation Visual Modeler for Grid Modeling and Simulation (GridSim) Toolkit
Motivation GridSim needs an easy-to-use user interface Reduce the learning curve of GridSim user GridSim user needs not know object-oriented concepts or Java. Advantages of having a visual design interface for GridSim
