Handling Complex Use Scenarios for Selection of Best Resources

Abstract

A Grid computing system is comprised of large sets of heterogeneous and geographically distributed resources that are aggregated for executing applica- tions.As the number of resources in Grids increases rapidly, selecting appropriate resources for jobs has become a crucial issue.To avoid single point of fail- ure and server overload problems, use scenario pro- vides an alternative means of resource selection in distributed systems.Here decentralized broker selects computational resources based on actual job require- ments, job characteristics, and information provided by the resources through webmds. Based on the previ- ous history of the resources and performance, we can specify that which resource is best from all the avail- able resources then run the job on that resource which ful lls the requirements of the job.
