资源摘要信息: "《C++并发编程实践》- C-C++ action thread" 本书《C++并发编程实践》深入探讨了C++语言在并发编程方面的应用,特别是C++11及其后续版本中引入的并发特性。C++作为一门强大的编程语言,在系统编程、游戏开发、高频交易系统、高性能服务器等需要高效处理多任务场景中有着广泛的应用。随着多核处理器的普及,能够有效利用并发编程提高程序性能显得尤为重要。 在并发编程中,“线程”是一个核心概念,它指的是程序中的一个执行流。在C++中,线程的创建和管理是实现并发的关键部分。本书详细讲解了如何在C++中创建和管理线程,以及如何通过线程同步机制(如互斥锁、条件变量、原子操作等)确保数据的一致性和线程的安全执行。 书中首先介绍了并发编程的基础知识,包括线程的基本概念、创建线程的方法以及线程间的同步与通信。随后,作者深入探讨了C++11引入的线程库,包括`<thread>`, `<mutex>`, `<condition_variable>`, `<future>`等头文件中定义的类型和函数。这些库提供了编写并发程序所需的工具,简化了多线程编程的复杂性。 在进一步学习中,书中还涉及了并发设计模式和策略,比如任务并行模式、数据并行模式、线程池以及异步编程模型。这些设计模式和策略能够帮助开发者在不同的并发编程场景中作出合理的设计选择。 书中还介绍了并发编程中的高级主题,包括无锁编程和内存模型。无锁编程主要涉及原子操作和原子类型,允许在不使用传统锁机制的情况下实现同步。C++内存模型是并发编程的基石,本书详细解释了C++11内存模型的规则及其对线程间通信的影响。 对于实际应用,本书还提供了如何在并发环境下进行测试和调试的策略,这是确保并发程序正确性和性能的关键步骤。最后,本书也探讨了C++标准库未来可能的发展方向,例如协程的引入,以及对并发编程可能带来的影响。 在现代C++编程实践中,理解和掌握并发编程是十分重要的。通过阅读《C++并发编程实践》,读者将能够深入了解C++中的并发概念,并且能够运用这些知识编写出既安全又高效的并发程序。无论你是刚接触并发编程的新手,还是已经有一定的经验希望提升自己技能的中级开发者,这本书都是一个很好的学习资源。 标签“C-C++ action thread”强调了本书专注于C++语言中线程的创建、管理与同步等关键操作。而标题“C++ Concurrency in Action”则体现了书籍的实践性质,即通过大量的实例和代码示例来展示理论知识在实际开发中的应用。通过这种方式,作者旨在帮助读者能够将并发编程的概念转化为有效的编程实践。

I encountered the concept of multithreaded code while working at my first job after I left college. We were writing a data processing application that had to populate a database with incoming data records. There was a lot of data, but each record was independent and required a reasonable amount of processing before it could be inserted into the database. To take full advantage of the power of our 10-CPU UltraSPARC, we ran the code in multiple threads, each thread processing its own set of incoming records. We wrote the code in C++, using POSIX threads, and made a fair number of mistakes—multithreading was new to all of us—but we got there in the end. It was also while working on this project that I first became aware of the C++ Standards Committee and the freshly published C++ Standard. I have had a keen interest in multithreading and concurrency ever since. Where others saw it as difficult, complex, and a source of problems, I saw it as a powerful tool that could enable your code to take advantage of the available hardware to run faster. Later on I would learn how it could be used to improve the responsiveness and performance of applications even on single-core hardware, by using multiple threads to hide the latency of time-consuming operations such as I/O. I also learned how it worked at the OS level and how Intel CPUs handled task switching. Meanwhile, my interest in C++ brought me in contact with the ACCU and then the C++ Standards panel at BSI, as well as Boost. I followed the initial development of the Boost Thread Library with interest, and when it was abandoned by the original developer, I jumped at the chance to get involved. I have been the primary developer and maintainer of the Boost Thread Library ever since.
