Sharing memory in modern distributed applications

Traditionally, research on software distributed shared memory has been focused on optimizing the memory consistency models and the coherence protocols rather than the underlying run-time mechanisms. Thus, these systems have been often implemented on top of the paging functionalities offered by the operating system. This approach, however, introduces performance issues due to false sharing of data. We propose an object-based approach that leverages the features of modern object-oriented programming to intercept single operations on data, hiding the underlying run-time mechanism. A possible implementation using the standard C++ programming language is shown and discussed.
