摘要： In one embodiment, a multi-core processor having cores each associated with a cache memory, can operate such that when a first core is to access data owned by a second core present in a cache line associated with the second core, responsive to a request from the first core, cache coherency state information associated with the cache line is not updated. A coherence engine associated with the processor may receive the data access request and determine that the data is of a memory page owned by the first core and convert the data access request to a non-cache coherent request. Other embodiments are described and claimed.

摘要： A method for evaluating objects in a data structure is provided. The method includes assigning one or more objects to one or more nodes in a data structure having at least a root node, in which the objects are assigned to the nodes in accordance with a first order to maintain pre-existing dependencies between the objects and to allow the objects to be evaluated in a serial manner to avoid deadlock when concurrently executing threads to evaluate the objects, and selecting a first object for evaluation, in response to determining that the current object is unevaluated.
摘要翻译： 提供了一种用于评估数据结构中的对象的方法。 该方法包括将一个或多个对象分配给具有至少根节点的数据结构中的一个或多个节点，其中根据第一顺序将对象分配给节点，以保持对象之间的预先存在的依赖关系，以及 允许以串行方式评估对象，以在同时执行线程以评估对象时选择第一对象以进行评估，以响应于确定当前对象未被评估而避免死锁。

摘要： A method for concurrent management of adaptive programs is disclosed wherein changes in a set of modifiable references are initially identified. A list of uses of the changed references is next computed using records made in structures of the references. The list is next inserted into an elimination queue. Comparison is next made of each of the uses to the other uses to determine independence or dependence thereon. Determined dependent uses are eliminated and the preceding steps are repeated for all determined independent uses until all dependencies have been eliminated.

摘要： In one embodiment, the present invention includes a cache memory having a plurality of cache lines to store data, in which at least some of the cache lines are adapted to store data in a compressed state. The cache memory also may include a first tag corresponding to each of the cache lines to indicate whether data in the corresponding cache line is compressible.
