Abstract: 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.

Abstract: 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.
