【摘要】 基于离散事件仿真平台si mJava的网格建模和仿真工具GirdSi m提供了大量用于仿真分布式系统的基础类。但是使用该工具进行仿真并不简单。除了编制大量代码之外,初学者还需要花费较长时间熟悉实验构造过程和各种基础类的使用方法。针对此问题,设计、实现了图形界面(Graphical User Interface,GUI)的仿真代码生成器GridSi mHelper,旨在缩短GridSi m平台的学习过程,减轻用户实施仿真实验的工作量。该工具允许用户对自行设计的调度算法进行仿真测试,并提供静态启发式算法min-min和max-min作为性能比较的对象。详细介绍了GridSi m-Helper的设计思路和实现细节。仿真实验结果证实了该工具的正确性和有效性。更多还原

【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 functionalities for effective simulations.For this end,we designed and implemented a GUI based code generator for GridSim,which is called GridsimHelper,with the aim of shortening the learning curve and enable fast creation of simulation models.The 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.更多还原
