Abstract: A method and corresponding tool, the method comprising: generating a lower-level control flow structure representing a portion of an executable program, the lower-level control flow structure comprising a plurality of lower-level nodes representing operations occurring within the program and a plurality of directional edges representing program flow between nodes; generating a higher-level control flow structure by matching a plurality of the lower-level nodes and edges to higher-level structure nodes representing internal structure, each higher-level structure node representing a group of one or more lower-level nodes and one or more associated edges; and using the higher-level control flow structure to estimate a timing property relating to execution of the program on a processor. The higher-level structure nodes are selected exclusively from a predetermined set of structure node patterns, each pattern in the set having at most one entry point and at most one exit point.

Abstract: A method and corresponding tool for estimating program execution time. A higher-level structure is received as an input, representing control flow through an executable program. The higher-level structure comprises one or more levels of parent nodes, each parent node representing internal structure comprising a group of one or more child nodes and one or more associated edges between nodes. The levels of the higher-level structure are probed to extract a substructure representing a route through the program from a start instruction to an end instruction, by selectively extracting nodes of different levels of parent to represent different regions along the route in dependence on a location of the start and end instructions relative to the levels of parent nodes. An execution time for the route through the program is estimated based on the extracted substructure, and a modification affecting the execution time is made in dependence on the estimation.

Abstract: A method for obtaining content using a calendar application is executed on a first electronic device. The method may include receiving travel parameters from a first user through a user interface of the calendar application. The travel parameters may include a destination and a date of travel. The method may further include obtaining destination information from a content source communicatively coupled to the first electronic device based on the travel parameters and notifying the first user of the obtained destination information at a predetermined time before the date of travel.

Abstract: A method, apparatus and computer program for controlling access to a publish/subscribe message broker. Publish/subscribe functions provided by the message broker are divided into function sets. Each function set is associated with a communication path. A request is received at the message broker via one of a plurality of communication paths and requests access to a publish or subscribe function provided by the message broker. It is determined which communication path is used and it is identified which function set the requested function is a part of. It is then determined whether the identified function set is associated with the communication path used; if the result is positive then access to the requested publish or subscribe function is provided.

Abstract: Summarization of text in a document may be requested in dependence upon the position of the text in relation to other text within the document or the position of the document containing the text within a plurality of documents in a document structure. Summarization of text in a document may also be requested in dependence upon a user's interaction with an application in conjunction with a version of the document or with a document structure including the document. Different levels of summarization may be applied to different segments of text within a document.

Abstract: A method for managing subscription requests in a publish/subscribe messaging system. Clients register a subscription at a message broker via one protocol and receive messages in matching that subscription on another protocol.

Abstract: A controller for use at a node of a clustered computer apparatus comprises an exception detection component for detecting an exception raised by a service component at the node; a quiesce component responsive to the exception detection component for quiescing lease-governed activity by the service component prior to termination of a lease; a lease control component responsive to the quiesce component for pre-expiry relinquishing of the lease; and a communication component responsive to the lease control component for communicating the pre-expiry relinquishing of the lease to one or more further nodes of said clustered computer apparatus. The controller may further comprise a further communication component for receiving a communication indicating the pre-expiry relinquishing of a lease; a further lease control component responsive to the communication to control failure processing; and a further service component to perform a service in place of the service component at the node.

Abstract: A broker-based publish/subscribe messaging system is administered in which a session-based network connection (such as TCP/IP) from an administrator publish/subscribe client application is established with a broker. Administration commands are received as messages from the administrator publish/subscribe client application at the broker via the session-based network connection and response messages are sent from the broker via the session-based network connection to only the administrator publish/subscribe client application.

The local message broker comprises publish/subscribe means for proxying messages between the client and the metabroker application means. The metabroker application means comprises publish/subscribe means for proxying messages between the local broker and the remote broker.

Abstract: A system for use in a publish/subscribe messaging system, the publish/subscribe messaging system having: a network, wherein the network has associated network data; and a broker having a matching engine for receiving at least one message from a publisher and for sending the at least one received message to a subscriber over the network. The at least one message has associated size metadata. The system comprises an intercept component for intercepting the at least one received message before sending by the matching engine and a receiving component for receiving the network data and the size metadata. A determining component, responsive to the receiving component, determines an instruction, which comprises a parameter associated with a time period over which the at least one received message is sent to the subscriber by the matching engine. The instruction is determined in accordance with the received network data and the size metadata.

Abstract: Subscribers connected to a publish/subscribe message broker receive messages on topic names to which they have subscribed. The messages are published with respective topic names within a sequence of topic names. The subscribers initially subscribe to at least one topic in the sequence, and then await receipt of a published message on the subscribed topic. On receipt of a published message, the subscriber unsubscribes from the subscribed topic and subscribes to a previously-unsubscribed next topic in the sequence.
