A semi-automatic parallelization tool for Java based on fork-join synchronization patterns

Abstract

Because of the increasing availability of multi-core machines, clusters, Grids, and combinations of these, there is now plenty of computational power. However, today’s programmers are not fully prepared to exploit distribution and parallelism. In this sense, the Java language has helped in handling the heterogeneity of such environments, but there is a lack of facilities to easily distributing and parallelizing applications. One solution to mitigate this problem seems to be the synthesis of semi-automatic parallelism and Parallelism as a Concern (PaaC), which promotes parallelizing applications along with as little modifications on sequential codes as possible. In this paper, we discuss a new approach that aims at overcoming the drawbacks of current Java-based parallel and distributed development tools.
