Resource Broker

Finally, the resource broker is agent whose responsibility is to find or reserve resources for the application programmer. The resource broker is represented in GAT through the class GATResourceBroker, an instance of which is used to find or reserve resources for the application programmer. Given a resource description the resource broker will proffer up all the known resources, to which the application has access rights, thus, finding resources based only on their description. In addition, the resource broker, given a resource description, can reserve a suitable resource for a user configurable time. The resource broker can also play this same tune when given a resource, not simply a resource description, allowing the application programmer to reserve specific resources.
