Integrating Memory Consistency Models and Communication Systems

The shared memory paradigm offers a well known programming model for parallel systems. But it lacks from its bad performance in conventional implementations if it is used in large grain or page based systems. The main problems are (1) the transparent view on the system level, (2) the false sharing caused by locating several consistency units into the same transportation unit, and that (3) high level software implementations are not integrated within the system architecture. The first point is addressed by annotating programming objects and deriving a specific configuration of system functionalities. The second point is solved by Game, the General and Autonomous Merging Environment which allows a multiple reader, multiple writer approach. The third point is directed by three implementation models of Game. A hardware based implementation and even a software based implementation are able to hide the costs of the local activities to perform Game by the network latency
