Abstract

An important mode of Grid operation is one in which a community or (as we call it here) a virtual organization (VO) negotiates an allocation from a resource provider and then disperses that allocation across its members according to VO policy. Implementing this model requires that a VO be able to deploy and operate its own resource management services within the Grid. We argue that a mechanism that allows for the creation, and subsequent monitoring and control, of managed computations provides a simple yet flexible solution to this requirement. We present an architectural framework that addresses the security, policy specification, and policy enforcement concerns that arise in this context. We also describe an implementation based on Globus Toolkit and Condor components, and present performance results.
