This chapter presents a toolkit for evaluation of resource management algorithms developed for Grid computing. This simulator named as EcoGrid and it is devised to support large number of resource or computing nodes and processes. Generally, grid simulators represent each resource using a thread that occupies large amount of space on the thread stack in main memory. However, EcoGrid models each node by an object instead of a thread. Memory space used by an object is much smaller than a thread, thus EcoGrid is highly scalable as compared to state-of-the-art simulators. EcoGrid is dynamically configurable and works with real as well as synthetic workloads. The simulator is bundled with a synthetic load generator that generates the workload using appropriate statistical distributions.
