The Gridkit Resource Management Frameworks

Traditional resource discovery and management systems in Grid Computing tend to be coarse-grained, have fixed static policies and deal exclusively with concrete resource entities e.g. CPUs, memory bytes. In this paper, we present the resource discovery and resource management frameworks that forms part of our Gridkit middleware. These frameworks are underpinned by an overlay network-based communications infrastructure which allows sophisticated and dynamically changeable resource discovery. In addition, we describe how our resource frameworks manage both coarse-grained and finegrained resources, and support abstract and pluggable task description to better support end-to-end quality of service.
