摘要： 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.

摘要： 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.
摘要翻译：公开了专门获取共享资源的技术。在一种方法方法中，该方法确定共享资源可用于由第一线程专门获取。该方法还防止第二线程在由第一线程独占地获取共享资源的操作期间的部分执行，这可以通过使用中断来实现。可以由第一线程启动防止第二线程的部分执行操作。然后，方法实施例执行由第一线程独占地获取共享资源的操作。

摘要： Granting an executable object (e.g., an application program, thread, or process) access to a namespace object (e.g., a named object, resource, file, or folder). A request by the executable object for the namespace object is intercepted and processed to determine whether a local namespace associated with the executable object, user, or session stores a copy of the requested namespace object. If the copy exists in one of the local namespaces, the request is granted and allowed to operate on that local namespace. If the requested namespace object exists only in a global namespace, the namespace object is copied to a local namespace. The request is then granted and allowed to operate on the copy of the namespace object in the local namespace. Protecting the namespace objects stored in the global namespace from modification improves the stability of the application program and operating system.
摘要翻译：授予对命名空间对象（例如，命名对象，资源，文件或文件夹）的可执行对象（例如，应用程序，线程或进程）的访问。用于命名空间对象的可执行对象的请求被截取并处理，以确定与可执行对象，用户或会话相关联的本地命名空间是否存储所请求的命名空间对象的副本。如果副本存在于其中一个本地命名空间中，则该请求将被授予并允许在该本地命名空间上运行。如果请求的命名空间对象仅存在于全局命名空间中，则命名空间对象将被复制到本地命名空间。然后，该请求被授予并允许在本地命名空间中的命名空间对象的副本上操作。保护存储在全局命名空间中的命名空间对象的修改可以提高应用程序和操作系统的稳定性。

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Granting an application program access to a resource as a function of a privilege associated with the application program. An embodiment of the invention employs a persistent, individual identity associated with the components of an application program or a group of application programs to allow an operating system to identify and differentiate between different application programs or groups of application programs installed on a computing system. The identity associated with each component of an application program enables the identification and removal or uninstallation of the application program. The identity also enables isolation of resources of the application program and protection of operating system resources.
