ScGridBroker: An Open Grid Resource Scheduler Based on Economic Scheduling Algorithms

This paper designs the ScGridBroker as an scheduler of ScGrid that uses grid technology for managing large-scale distributed resources based on Economic Scheduling Algorithms. It discusses a layered and component-oriented modular architecture for the broker design and development. The architecture is generic enough to leverage services provided by various Grid middleware systems such as Globus, Legion, and Condor for uniform access to diverse resources. It briefly discusses the deadline and budget constrained scheduling algorithms that we have incorporated into the ScGridBroker.
