Leveraging Threading and Concurrency
Most computers contain multiple processors or at least multiple cores, and leveraging this computational power is the key for many categories of applications. Unfortunately, many developers still have a mindset of sequential code execution, even though operations that do not depend on each other could be executed concurrently. This chapter presents standard library support for threads, asynchronous tasks, and related components, as well as some practical examples at the end.
Most modern processors (except those dedicated to types of applications that do not require great computing power, such as Internet of Things applications) have two, four, or more cores that enable you to concurrently execute multiple threads of execution. Applications must be explicitly written to leverage the multiple processing units that exist; you can write such applications by executing functions on multiple threads at the same time. The C++ standard library...
