Seven Concurrency Models in Seven Weeks

Roads Not Taken

One of the hardest decisions we had to make when creating this book was what to leave out. Here’s a quick summary of the roads we didn’t take, as well as some pointers if you want to investigate them yourself.

Fork/Join and Work-Stealing

Fork/Join is an approach to parallelism popularized by the Cilk language,^[81] a parallel variant of C/C++, but implementations are now available for many environments, including Java.^[82] Fork/Join is particularly suited to divide-and-conquer algorithms, such as those we saw in ​Divide and Conquer​ (indeed, Clojure’s reducers make use of Java’s Fork/Join framework under the hood).

Fork/Join implementations typically make use of work-stealing to share tasks across a thread pool, ...
