Virtual Grids: Adaptive Resource Environments for High Performance Grid Applications

Abstract Grid applications are highly dependent on the description, selection and binding of the resources. The supporting middleware must be able to hide the complexity of the underlying resources, yet provide the user with the ability to control them in different granularity levels. A Virtual Grid is an abstraction that can handle complex and dynamic resource environments simplifying the development of an application. This is accomplished through our execution system (vgES) which includes a very strong and novel description language (vgDL) and an efficient resource selection and binding mechanism (vgFAB). Adaptation is also facilitated by a distributed monitoring component (vgMON), ensuring in either a transparent or application-directed fashion, that application requirements are met. Both static and dynamic resource information in vgES are provided by an intelligent agent either through batch or on-demand request. Experiments on the prototype implementation of vgFAB show that the mechanism employed is efficient and scalable with respect to request complexity, grid size and workload, providing quantifiably good matches quickly. Robustness is also verified by simulating failure and resource contention scenarios.
