摘要： A multi-processor computer system in which each processor is under the control of separate system software and access a common database. A two level lock management system is used to prevent data corruption due to unsychronized data access by the multiple processors. By this system, subsets of data in the database are assigned respectively different lock entities. Before a task running on one of the processors access data in the database it first requests permission to access the data in a given mode with reference to the appropriate lock entity. A first level lock manager handles these requests synchronously, using a simplified model of the locking system having shared and exclusive lock modes to either grant or deny the request. All requests are then forwarded to a second level lock manager which grants or denies the request based on a more robust model of the locking system and queues denied requests. The denied requests are granted, in turn, as the tasks which have been granted access finish processing data in the database.

摘要： A protocol for a switching system that establishes multiple parallel paths between users through multiple autonomous switching planes by having a user desiring connection to issue connection requests to each of the switching planes. According to the invention, the user monitors the number of connections that have been successfully completed and if only some of the connections have been completed, because of conflicting requests, it follows a conflict protocol to issue retry requests to the planes on which the connection request was unsuccessful. Each switching plane follows the conflict protocol to respond to the retry request by disconnecting existing connections and completing at most one retried connection request.

摘要： Streaming environments typically dictate incomplete or approximate algorithm execution, in order to cope with sudden surges in the data rate. Such limitations are even more accentuated in mobile environments (such as sensor networks) where computational and memory resources are typically limited. Introduced herein is a novel “resource adaptive” algorithm for spectrum and periodicity estimation on a continuous stream of data. The formulation is based on the derivation of a closed-form incremental computation of the spectrum, augmented by an intelligent load-shedding scheme that can adapt to available CPU resources. Experimentation indicates that the proposed technique can be a viable and resource efficient solution for real-time spectrum estimation.

摘要： One embodiment of the present method and apparatus adaptive in-operator load shedding includes receiving at least two data streams (each comprising a plurality of tuples, or data items) into respective sliding windows of memory. A throttling fraction is then calculated based on input rates associated with the data streams and on currently available processing resources. Tuples are then selected for processing from the data streams in accordance with the throttling fraction, where the selected tuples represent a subset of all tuples contained within the sliding window.

摘要： A computer-implemented method, system, and a computer readable article of manufacture identify local patterns in at least one time series data stream. A data stream is received that comprises at least one set of time series data. The at least one set of time series data is formed into a set of multiple ordered levels of time series data. Multiple ordered levels of hierarchical approximation functions are generated directly from the multiple ordered levels of time series data. A set of approximating functions are created for each level. A current window with a current window length is selected from a set of varying window lengths. The set of approximating functions created at one level in the multiple ordered levels is passed to a subsequent level as a set of time series data. The multiple ordered levels of hierarchical approximation functions are stored into memory after being generated.
