Division of labor: Tools for growing and scaling grids

Abstract

To enable Grid scalability and growth, a usage model has evolved whereby resource providers make resources available not to individual users directly, but rather to larger units, called virtual organizations. In this paper, we describe abstractions that allow resource providers to delegate the usage of remote resources dynamically to virtual organizations in application-independent ways, and present and evaluate an implementation of this abstraction using the Xen virtual machine and Linux networking tools. We also describe how our implementation is being used in a specific context, namely the enforcement of resource allocations in the Edge Services Framework, currently deployed in the Open Science Grid. © 2006 Springer-Verlag.
