In this paper,we present a distrubuted computing scheme for exmination feedback analysis based on grid.The proposed scheme is motivated by the observation that as the number of examinations increases,the feedback analysis would become extremely slow if a single server is used.Grid computing can be used to solve the problem by evenly distributing the workloadof the system to all the available nodes,thus greatly enchanting the performance of feedback analysis in a learning system.We use Hyper Grid Learning System (HGLS)-a learning system with examination service-we developed as an example to describe the propossed scheme.We note that althought discussed in the context of HGLS,the propossed scheme can be easily adapted and applied to all the e-learning systems based on Grid computing.To evaluate the performanceof the propossed scheme,we compare the performance of the propossed scheme with single node servers.Our exprimental result shows that performance of the feedback analysis in a learning system base on grid.
