Notice how the TPL is only a small building block of a bigger story. In our coverage of task and data parallelism in this chapter, we focus on the TPL but also PLINQ, which, strictly speaking, is a different component. Let’s talk about the layering a bit more.

At the bottom of the diagram, you can see a number of threads that correspond to the processors ...
