Description

Multi-core chips from Intel and AMD offer a dramatic boost in speed and responsiveness, and plenty of opportunities for multiprocessing on ordinary desktop computers. But they also present a challenge: More than ever, multithreading is a requirement for good performance. This guide explains how to maximize the benefits of these processors through a portable C++ library that works on Windows, Linux, Macintosh, and Unix systems. With it, you'll learn how to use Intel Threading Building Blocks (TBB) effectively for parallel programming -- without having to be a threading expert.

Written by James Reinders, Chief Evangelist of Intel Software Products, and based on the experience of Intel's developers and customers, this book explains the key tasks in multithreading and how to accomplish them with TBB in a portable and robust manner. With plenty of examples and full reference material, the book lays out common patterns of uses, reveals the gotchas in TBB, and gives important guidelines for choosing among alternatives in order to get the best performance.

You'll learn how Intel Threading Building Blocks:
  • Enables you to specify tasks instead of threads for better portability, easier programming, more understandable source code, and better performance and scalability in general
  • Focuses on the goal of parallelizing computationally intensive work to deliver high-level solutions
  • Is compatible with other threading packages, and doesn't force you to pick one package for your entire program
  • Emphasizes scalable, data-parallel programming, which allows program performance to increase as you add processors
  • Relies on generic programming, which enables you to write the best possible algorithms with the fewest constraints
Any C++ programmer who wants to write an application to run on a multi-core system will benefit from this book. TBB is also very approachable for a C programmer or a C++ programmer without much experience with templates. Best of all, you don't need experience with parallel programming or multi-core processors to use this book.

描述

多核芯片由英特爾和AMD提供,可以大幅提升速度和反應能力,並為普通桌面電腦提供了許多多處理的機會。但是,它們也帶來了一個挑戰:多線程是良好性能的要求。本指南介紹了如何通過一個可在Windows、Linux、Macintosh和Unix系統上運行的可移植C++庫來最大化這些處理器的好處。通過這本書,您將學習如何有效地使用英特爾線程構建塊(TBB)進行並行編程,而無需成為線程專家。

本書由英特爾軟件產品的首席傳教士James Reinders撰寫,基於英特爾的開發人員和客戶的經驗,該書解釋了多線程中的關鍵任務以及如何以可移植和堅固的方式使用TBB來完成這些任務。書中提供了大量的示例和完整的參考資料,介紹了常見的使用模式,揭示了TBB中的注意事項,並提供了在選擇不同方案時獲得最佳性能的重要指南。

您將學習到英特爾線程構建塊的以下特點:
- 通過指定任務而不是線程來提高可移植性、編程更容易、源代碼更易理解,並獲得更好的性能和可擴展性
- 專注於並行化計算密集型工作的目標,提供高級解決方案
- 與其他線程包兼容,不強制您選擇一個包來完成整個程序
- 強調可擴展的數據並行編程,允許隨著添加處理器而提高程序性能
- 依賴於通用編程,使您能夠以最少的限制編寫最佳的算法

任何想要在多核系統上運行應用程序的C++程序員都會從本書中受益。對於C程序員或沒有太多模板經驗的C++程序員來說,TBB也非常容易上手。最重要的是,您不需要有並行編程或多核處理器的經驗來使用本書。
