摘　　要：针对校园网格主要应用于科学计算的特点,面向应用提出并实现了一种评估资源是否适宜分配作业的算法,指导校园网格应用合理分配作业,实现校园网格系统中作业运行时间短和资源负载平衡。重点阐述了网格资源的作业适宜分配度算法,包括网格资源的初始权重算法、信誉度算法和动态负载算法,完善了网格资源评估体系。最后通过仿真实验对资源评估算法完成了验证,证明所提出的算法是可行并有效的。Based on the feature of school grid, which mainly focus on science computing, an algorithm faced to application field is presented which is used for evaluating resource weather or not fitting for jobs. It is used for directing the reasonable dispatchment of jobs in school grid, for it can shorten time of jobs and fulfil resource load balance within school grid. An algorithm of job fitting weight （JFW） of resource is mainly stated, which includes the algorithm of initial weight of resource, the algorithm of resource credit and the algorithm of dynamic load, and which completes the resource evaluation system. Emulation experiments show that the new policy is efficient and valuable within school grid computing system.
