Performance evaluation of Grid simulators using profilers

Profilers are the performance analysis tools that produce the traces of the execution of the applications developed in various programming languages. These traces can be analyzed to determine the performance of the applications. This paper compares the performance of two Grid simulators developed in Java namely the EcoGrid (developed by the authors of the paper) and GridSim. The profiler tool available with the NetBeans integrated development environment has been used. The scalability, memory usage and the runtime performance of the simulators are tested on the profilers. We showed that EcoGrid has much better performance as compared to GridSim.
