Fork/Join

Fork-join framework

There are new Java concurrency APIs (JSR 166y) referred to as the Fork-join framework. It is designed for tasks that can be broken down and takes advantage of multiple processors. The following are the core classes (all located in java.util.concurrent):

• ForkJoinPool: An ExecutorService for running ForkJoinTasks and managing and monitoring the tasks.
• ForkJoinTask: This represents the abstract task that runs within the ForkJoinPool.
• RecursiveTask: This is a subclass of ForkJoinTask whose compute method returns some value.
• RecursiveAction: This is a subclass of ForkJoinTask whose compute method does not return any value.
