VGES: the Next Generation of Virtualized Grid Resource Provisioning

Abstract. New science in many important disciplines now requires complex, time-dependent access to distributed computing resources. We addresses these problems by creating a higher level resource abstraction that layers on top of existing Cyberinfrastructure that allows an application to target stable resource aggregations spanning sites through a well-defined and standard-compatible interfaces. The functionality of vgES automatically maps application centric Virtual Grid specifications onto available resources through a split-phase provisioning and actualization protocol. Clients of vgES see all resources in terms of single resource slot abstraction that can be treated as a form of advanced resource reservation even when underlying resource do not support such reservations directly.
