Abstract

New trends in parallel computing are moving towards multicore processors. A new factor then arises in such scenario, concurrence . But concurrence is not parallelism. Parallel applications that wish to take advantage of this new environment need to take this into consideration, or being completely rewritten in such a way that parallelism can be expressed by means of concurrence. In this evolving scenario, abstractions may help to keep performance. This paper shows how abstractions play an important role from the performance and scalability perspective when used to model the problem.
