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

Visual Modeler for Grid Modeling and Simulation (GridSim) Toolkit

Functionalities Enables easy and quick creation of many Grid testbed users and resources Generates the simulation scenario into Java code that the users can compile and execute the GridSim-based simulation Saves and retrieves a VM project file that contains an experiment scenario in XML format Works on different operating system platforms using Java Virtual Machine (JVM)
