Appl. No.:

12/147531

Inventors:

Erez Haba - Redmond WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 9/44

US Classification:

719312, 719313, 719314, 719315, 719316, 717106, 717127, 717131, 717162, 717167, 718 1, 718100, 718105, 718107, 718108, 710200, 710220, 713300, 711100, 711147, 709213, 709248

Abstract:

Two threads may communicate via shared memory using two different modes. In a polling mode, a receiving thread may poll an indicator set by the sending thread to determine if a message is present. In a blocking mode, the receiving thread may wait until a synchronization object is set by the sending thread which may cause the receiving thread to return to the polling mode. The polling mode may have low latency buy may use processor activity of the receiving thread to repetitively check the indictor. The blocking mode may have a higher latency but may allow the receiving thread to enter a sleep mode or perform other activities.

International Classification:

G06F 15/16

US Classification:

370510, 709246

Abstract:

Two clocks may be synchronized by calculating skew and offset values that may be determined from several correlation events. A correlation event may be the passing of messages in both directions between the two devices. The skew and offset values may be used to determine the time of non-correlated events. The clock synchronization may be performed on a real time basis or may be performed on a post processing basis. One method for calculating the skew and offset may use inequalities within a solution space to refine a solution set with multiple sets of correlation events.

International Classification:

G06F009/44

US Classification:

717122000, 717124000

Abstract:

The present invention provides for a test management system that maintains fine-grained versioning information without sacrificing query, filtering, and reporting capabilities. Metadata associated with a test is stored in an XML file that is versioned with the test assets and source code. Furthermore, the XML file can contain all the attributes necessary for query and management, for example via XSLT transformations.
