Simulation plays an important role in grid research. However, there is no general simulation environment for scheduling algorithms testing. In this paper we establish an extendable grid sim- ulation environment based on GridSim by choosing and extending the appropriate modules of an open-source grid simulation environment—- gridbroker. In our simulation environment, users can easily add various different scheduling policies into the task scheduler and don't need to encode for other parts of the environment repeatedly. The environment's scalability was verified by extending its task scheduler using a scheduling policy based on the ant algorithm in the last part of this paper.
