Introducing Aspects to the Implementation of a Java Fork/Join Framework.

Chrysoulis Zambas and Mikel Luján.


When faced with the question of how will a program exploit the current and upcoming chip multiprocessors, many answers can be produced. Two of the most promising answers are: (1) frameworks or libraries where experts have encapsulated the parallelism, and (2) work stealing as a means of load balancing the work. This paper presents a study of whether aspect-oriented programming can benefit the implementation of a well-known Java framework for divide-and-conquer applications that relies on random work stealing. Despite different kinds of aspects being introduced, the performance evaluation shows no significant overhead due to their inclusion.
