Parallelism as a Concern in Java through Fork-join Synchronization Patterns

We are facing a hardware revolution given by the increasing availability of multicore computers, clusters, Grids, and combinations of these. Consequently, there is plenty of computational power, but today´s programmers are not fully prepared to exploit parallelism and distribution. Particularly, Java has helped in handling the heterogeneity of such environments, but there is a lack of facilities to easily and elegantly parallelizing applications. One path to this end seems to be the synthesis of semi-automatic parallelism and Parallelism as a Concern (PaaC). We briefly survey relevant Java-based parallel development tools, identify their drawbacks, and discuss some insights of an ongoing approach for mitigating them.
