Task-based parallelism in C++

A task is a computation that can be potentially executed concurrently with other computations. A thread is a system-level representation of a task. In the previous chapter, we learned how to execute a task concurrently with other tasks launched by constructing an std::thread object with the task as its argument to the constructor. A task can be any callable object such as a function, Lambda, or a functor. But this approach of executing a function concurrently using std::thread is called a thread-based approach. The preferred choice for concurrent execution is a task-based approach, and this will be discussed in this chapter. The advantage of a task-based approach over a thread-based approach is to operate at ...
