Abstract: The Grid Modeling and Simulation toolkit GridSim provide a lot of basic tools to simulate essential components of distributed system. However, the process of simulation is not simple. Except for the necessity to write Java code that used the GridSim toolkit packages;new learner must experience the long learning curve in order to utilize the toolkit functionalitics for effective simulations. For this end, we designed and implemented a GUI based cock generator for GridSim, which is called GridsimHelper, with the aim of shortening the learning curve and enable fast creation of simulation models. I}he code generator provides facility for users to input and evaluate the performance of any scheduling algorithm,as well as baseline algorithm(provided by GridsimHelper) min-min and max-min for comparison. This paper gave the implementation details of GridsimHelper, and the experimental results illustrate the correctness and usefulness of GridsimHelper.
