Abstract:

A node manager () resides on a node () in a cluster computing system () and transfers information and events being communicated across the node () to a broker () coupled to the node manager (). The broker () transmits information to client devices () who subscribe to particular events. The client devices () publish their own messages back to the broker () or to a second broker (). Other client device () can then subscribe to receive the messages from either broker (or ). The other client devices () can then publish their own messages back to the brokers for subscription by further client devices ().

Abstract:

A method and system are disclosed for indexing a set of statements, such as RDF statements, that are described in accordance with a specified ontology. The method comprises the steps of defining a set of indexing rules, and using these indexing rules to examine the statements to identify selected ones of the statements and to generate one or more indices from said selected ones of the statements. In a preferred embodiment, the rules match certain predicates of RDF statements to certain indices. Also, preferably, an RDF storage system may be configured with said set of indexing rules. When RDF statements are added to the RDF storage system, each statement is examined by the indexing subsystem. If the predicate of a statement matches one of the predicates of said set of indexing rules, that rule is applied to the statement.

Abstract:

A node manager () resides on a node () in a cluster computing system () and transfers information and events being communicated across the node () to a broker () coupled to the node manager (). The broker () transmits information to client devices () who subscribe to particular events. The node manager () includes an adapter () that interprets events occurring on the system and publishes messages to the broker, and a system probe () that publishes information to the broker () in accordance with a configurable schedule. An autonomic agent () measures the rate of information loss between the node () and client () and regulates the rate of information by adjusting one or more information flow control points within the system once an overload state is detected.
