Credit in the grid resource management

Grid computing systems that have been the focus of much research activities in the past years for controlled sharing of resources across institutional boundaries. Trust is one major concern in grid resource management that enables remote scheduling and execution. Reputation mechanism can be used for providing trust in Grid systems, but the additional overhead caused by it negate the performance advantages gained by Grid computing. Besides, Reputation mechanism is not suitable for large-scale resource sharing. In this paper, we present a credit model for Grid resource management that is based on computational economy and show how the model can be used to incorporate the trust implications into scheduling algorithms. Simulations are performed to evaluate the performance.
