1.4.2 Work Crew Model

In the work crew model, multiple threads work together on a single task. The task is divided horizontally into pieces that are performed in parallel, and each thread performs one piece. An example of a work crew is a group of people cleaning a building. Each person cleans certain rooms or performs certain types of work (washing floors, polishing furniture, and so forth), and each works independently.

Figure 1-4 shows a task performed by three threads in a work crew model.
