Coupling grid applications developed by different teams requires code modification and high S/W engineering effort. In the Ensemble methodology message passing components are deve...
Collective operations are an important aspect of the currently most important message-passing programming model MPI (Message Passing Interface). Many MPI applications make heavy u...
Developing and debugging parallel programs particularly for distributed memory architectures is still a difficult task. The most popular approach to developing parallel programs f...
