Cyclotron: A Secure, Isolated, Virtual Cycle-Scavenging Grid in the Enterprise

Cycle-scavenging grids appeal to organizations with large numbers of workstations that remain idle outside of normal working hours. This represents a potential source of grid computing cycles, but the security and isolation issues that come with the use of non-dedicated resources have slowed their adoption in the enterprise. In this paper we present Cyclotron, a prototype cycle-scavenging grid solution that leverages virtualization and a declarative security policy-based access control infrastructure, supporting flexible authorization rules and the constrained delegation of access rights, to address these requirements.
