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.<\/p>\n<p>This is an extended journal version of an earlier workshop paper.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cycle-scavenging grids appeal to organizations with large numbers of workstations that remain idle outside of normal working hours.
