Efficient resource description and high quality selection for virtual grids

Simple resource specification, resource selection, and effective binding are critical capabilities for Grid middleware. We the Virtual Grid, an abstraction for dynamic grid applications to deal with complex resource environments. Elements of the Virtual Grid include a novel resource description language (vgDL) and a resource selection and binding component (vgFAB), which accepts a vgDL specification and returns a Virtual Grid, that is, a set of selected and bound resources. The goals of vgFAB are efficiency, scalability, robustness to high resource contention, and the ability to produce results with quantifiable high quality. We present the design of vgDL, showing aptures application-level resource abstractions using resource aggregates and connectivity amongst them. We present and evaluate a prototype implementation of vgFAB. Our results show that resource selection and binding for virtual grids of 10,000’s of resources can scale up to grids with millions of resources, identifying ...
