CORS - A Cost Optimized Resource Reservation Scheme for Grid

The basic objective of grid computing is to support resource sharing among individuals and institutions within a networked infrastructure. Managing various resources in highly dynamic grid environments is a complex and challenging problem. Some approaches apply algorithms for resource management to grid but fails to provide any generalized solutions. Most of the approaches are based on a simple architecture considering computer as the main resource. But the real architecture of grid computing is a complex one especially if we consider various resources of a computer (e.g., processor, memory etc.) during resource management. In grids, sometimes assurance is needed for successful completion of jobs on shared resources. Such guarantees can only be provided by reserving resources in advance. So resource reservation is an integral part of resource management system for grid. Moreover the cost for providing resource as services will play a significant role in near future when resource sharing will be popular and inevitable. In this paper we provide a future reservation supported and cost optimized novel resource management system (CORS) for grid environment considering its real complex architecture. We further conduct a detailed performance evaluation with comparison on real workload traces
