Mastering Concurrency Programming with Java 8

A methodology to design concurrent algorithms

In this section, we're going to propose a five-step methodology to get a concurrent version of a sequential algorithm. It's based on the one presented by Intel in their Threading Methodology: Principles and Practices document.

The starting point – a sequential version of the algorithm

Our starting point to implement a concurrent algorithm will be a sequential version of it. Of course, we can design a concurrent algorithm from scratch, but I think that a sequential version of the algorithm will give us two advantages:

• We can use the sequential algorithm to test if our concurrent algorithm generates correct results. Both algorithms must generate the same output when they receive the same input, so we can ...
