A decentralized hierarchical scheduler for a grid-based clearinghouse

Grid technologies enable large-scale resource sharing among enterprises and/or individuals. In such settings, control policies must be administered so that resource cart be fairly shared among participating enterprises. A grid-based clearinghouse for managing shared resources is built with the aim of promoting technical and scientific cooperation within and between campuses. We therefore, need a global mechanism for exchanging and integrating resource and hence, maximize computation throughput through the coordination of shared resources. The major process involved is the development of a job management strategy that realizes the objectives of the clearinghouse. In this paper, we introduce the design and application of a decentralized hierarchical scheduler for job management. A working testbed for this scheduler is to be implemented on a campus grid. The campus grid is a hierarchical grid that is built with the Globus Toolkit inter-operated with a group of Sungrid Engine clusters.
