Abstract: There are provided methods for single-owner multi-consumer work queues for repeatable tasks. A method includes permitting a single owner thread of a single owner, multi-consumer, work queue to access the work queue using atomic instructions limited to only a single access and using non-atomic operations. The method further includes restricting the single owner thread from accessing the work queue using atomic instructions involving more than one access. The method also includes synchronizing amongst other threads with respect to their respective accesses to the work queue.

Abstract: Systems and methods for replacing inferior code segments with optimal code segments. Systems and methods for making such replacements for programming languages using Message Passing Interface (MPI) are provided. For example, at the compiler level, point-to-point code segments may be identified and replaced with all-to-all code segments. Programming code may include X10, Chapel and other programming languages that support parallel for loop.

Abstract: Work-stealing is efficiently extended to distributed memory using low degree, low-diameter, fully-connected directed lifeline graphs. These lifeline graphs include k-dimensional hypercubes. When a node is unable to find work after w unsuccessful steals, that node quiesces after informing the outgoing edges in its lifeline graph. Quiescent nodes do not disturb other nodes. Each quiesced node reactivates when work arrives from a lifeline, itself sharing this work with its incoming lifelines that are activated. Termination occurs when computation at all nodes has quiesced. In a language such as X10, such passive distributed termination is detected automatically using the finish construct.

Abstract: A technique for enabling a browser to update its state upon a change between voice and visual mode. A deck of visual content cards is loaded into a visual browser, wherein one card contains a link to change from visual to voice mode. Selecting the link directs the visual browser to an update card, which has a first event handler which enters voice mode by placing a voice call to a telephone number in response to forward entry into the update card. The update card also includes a second event handler which contacts an update site to determine what content to point the visual browser to when visual mode resumes. In a first embodiment, the second event handler is actuated by backward entry into the update card upon completion of the voice call. In a second embodiment, the second event handler is actuated by expiration of a timer.

Abstract: A technique for providing multi-modal interaction with a directory. A user of a telephone set connects to a directory service, such as a directory assistance service that provides telephone numbers. The user interacts with the system, either by engaging in voice communications with a human operator, or by interacting with an automated system that employs voice recognition. The directory service then provides the requested information (e.g., a requested telephone number) to the user in the form of data that can be captured and used by the telephone—e.g., if the requested information is a telephone number, the telephone may store the data representation of that number in a contacts list, or place a call to the number without the user having to enter the number with a keypad.
