山东师范大学硕士学位论文ABSTRACT 山东师范大学硕士学位论文 ABSTRACT Grid computing is a fast developing、vi(1e nd[wDrk computing technique．The researchers try tO integrate geographically distributed Computer system to a large scale computing plat form named”Grid”．According to it,1l!；e幅can use resources their needed conveniently without knowing the detail procedure．The鲥d provid器users all kinds of data information and multimedia application in addition to low cost and high performance computing．However,Grid computing is a new research field and Grid environment has more complex features than general network,as rejoices are autonomous,owned by different individuals Or organizations and玎加犯 distributed,the determinism in communications dehy is not high,the isomcrism in the hardwar, and the software two levels and t；0 011．In order to implement efficient Grid computing many problems must be solved including resource managemem and scheduling,system security, programming scheme，performance evaluation,data access etc．Then how to manage and sche叫e rcsourecs in Grid environment is one ofthe key factors that dek：rmine whether the Grid computing Can get a high performance．As the resources are geographically distribmed and heterogeneous in Grid environment, rcsource management becomes morc complex and challenging． 11舱thesis is looking for a more reasonable Grid rcsource management model and more e伍cient scheduling policy based on the characteristics of Grid resources．This article thoroughly has analyzed the鲥d resourC七management present situation，at the sanle time，snmnlarized in the present grid resource management technology deficiency,proposed a面d rcsourc跫 management model b笛ed On Agentthe central management-local coordination assignment”： On the other hand it has carried on the thomugh discussion to under the grid environment scheduling algorithm model and the present quite classical grid scheduling algorithm,proposed optimized generation scheduling algorithm(Oos)． Based on previous research,the major r
