Patent number: 7770170Abstract: A blocking local sense synchronization barrier is provided. The local sense variable is not processor private or global, but truly local to the synchronization barrier function. Safe deletion is provided by making sure the last operation a thread performs on a barrier is a write. Just before returning, threads increment a field that indicates the count of threads that have left the barrier. Blocking is supported such that threads spin for some interval, and when they decide to block, examine and set (if not already set) the indication of whether a thread is blocking that is to be examined by the last thread to arrive at the barrier to determine whether to set an event to release blocking threads.Type: GrantFiled: July 12, 2005Date of Patent: August 3, 2010Assignee: Microsoft CorporationInventors: John Rector, Jonathan D. Morrison, Neill M. Clift, Arun U. Kishan

Patent number: 7756841Abstract: A system and method for identity decisions and invalidation. Modified objects (e.g., files, executables, etc.) are flagged for reevaluation. Privileges associated with the object are only persisted if the modifications are determined to be authorized (e.g., updates and patches). In one embodiment, a tagging system registers to be notified of all writes, renames, truncations, moves, deletions, or any other relevant modifications to objects. If the tagging system detects a modification operation targeting the object, it invalidates all identity decisions cached with the object. The next time the object runs, the system does not recognize the object and it is forced to reevaluate its identity. Thus, patching and other write operations are still permitted, but the system detects the changed object and reevaluates the identity.Type: GrantFiled: March 22, 2005Date of Patent: July 13, 2010Assignee: Microsoft CorporationInventors: David B. Probert, Eric Li, Genevieve Fernandes, John Rector

Publication number: 20070094669Abstract: A technology for exclusively acquiring a shared resource is disclosed. In one method approach, the method determines that a shared resource is available to be exclusively acquired by a first thread. The method also prevents partial execution of operations by a second thread, during operations to exclusively acquire the shared resource by the first thread, which may be accomplished by using an interrupt. The preventing of partial execution of operations by the second thread may be initiated by the first thread. The method embodiment then performs operations to exclusively acquire the shared resource by the first thread.Type: ApplicationFiled: October 25, 2005Publication date: April 26, 2007Applicant: Microsoft CorporationInventors: John Rector, Arun Kishan, Neill Clift, Adrian Marinescu

Publication number: 20070039056Abstract: A multi-level sequence number is associated with a data provider supplying data for an object. The multi-level sequence number includes a portion that is unique to the data provider, and one or more portions that are shared by other data providers for the object. A per-object table is used to cache data supplied by each data provider for the object and the corresponding multi-level sequence number. A global table associates each data provider with the current value of its multi-level sequence number. Whenever data supplied by a data provider changes, the sequence number in the global table is updated. Cached data of the data provider is updated with current data of the data provider only if the cached value of the sequence number is found to be different from the current value of the sequence number.Type: ApplicationFiled: August 15, 2005Publication date: February 15, 2007Applicant: Microsoft CorporationInventors: John Rector, Eric Li

Publication number: 20060103043Abstract: The invention discloses method and apparatus for providing a desired batch flow through desired regions of an extrusion die for forming honeycomb structures, and more particularly to the enhancement of batch flow in the skin-forming region of the die so as to provide a bounding wall of desired thickness and strength about a honeycomb core. Unlike prior methods, a recess or trough of desired depth and width is formed in a desired region of the inlet face of the honeycomb die, which reduces the pressure required to flow batch material through the die in such region. Such reduced pressure requirement translates in an increased flow rate in such region under constant extrusion pressure. Thus by increasing the flow rate through a honeycomb extrusion die in an outer peripheral region of flow in this manner, improved skin formation around a honeycomb core is obtained during the forming process.Type: ApplicationFiled: May 23, 2005Publication date: May 18, 2006Inventor: John Rector
