Division of Labor: Tools for Growing and Scaling Grids
نویسندگان
چکیده
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 applicationindependent 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.

To enable Grid scalability and growth, a usage model has evolved where resource providers make resources available not to individual users directly, but rather to larger units, called virtual organizations (VOs). This enables the resource provider to focus on the dynamics of providing resources to the VOs while VOs specialize to provide resources to their users. Achieving such division of labor...
