A credit evaluation model for computational grid nodes

Computational Grid is a cooperative computing environment which collects all kinds of high performance software and hardware computing resources distributed in WAN and provides networked computing services. The computational grid systems that have been the focus of much research activities in the past years for controlled sharing of resources across institutional boundaries. Credit is one major concern in grid resource management that enables remote scheduling and execution. For the sake of improving the self-adaptability of resource management and accelerating the application and development of Computational Grid, an evaluation model of a computational grid node's credit is put forward which is based on the execution results of computational grid jobs on the node. Using this model the resource consumers and resource providers should abandon the vicious evaluating voluntarily. Applied in NPU Campus Computational Grid, this model achieves good effect.
