Related to grid networks are grid services, which extend existing web services technology in a number of ways, the most important being persistence. The current standard in this area is OGSA, the Open Grid Service Architecture, which is managed by the GGF (Global Grid Forum).
At present grid services form a handshaking layer that enables grid networks to work across diverse sites, although a move toward using grid services to provide applications is possible. Currently however, grid services are used to provide a standard interface to existing job managers.
In traditional ad-hoc methods, a configuration is specified as it is realised by the system administrator altering the files on the target machine. As the number of nodes grows, this approach fails to scale. In automated configuration, the specification is done on a server and tools on the target node bring the configuration to the desired state.
The solution being investigated by this project is whether automated configuration tools can be used within the grid fabric to change the configurations of nodes based upon the application they are asked to execute.
The project work will commence with a review of the configuration requirements at a number of grid centres, followed by a proof of concept implementation on a test fabric of dynamic reconfiguration.
