Summary

OpenCL in Action is a thorough, hands-on presentation of OpenCL, with an eye toward showing developers how to build high-performance applications of their own. It begins by presenting the core concepts behind OpenCL, including vector computing, parallel programming, and multi-threaded operations, and then guides you step-by-step from simple data structures to complex functions.

About the Technology

Whatever system you have, it probably has more raw processing power than you're using. OpenCL is a high-performance programming language that maximizes computational power by executing on CPUs, graphics processors, and other number-crunching devices. It's perfect for speed-sensitive tasks like vector computing, matrix operations, and graphics acceleration.

About this Book

OpenCL in Action blends the theory of parallel computing with the practical reality of building high-performance applications using OpenCL. It first guides you through the fundamental data structures in an intuitive manner. Then, it explains techniques for high-speed sorting, image processing, matrix operations, and fast Fourier transform. The book concludes with a deep look at the all-important subject of graphics acceleration. Numerous challenging examples give you different ways to experiment with working code.

A background in C or C++ is helpful, but no prior exposure to OpenCL is needed.

What's Inside
  • Learn OpenCL step by step
  • Tons of annotated code
  • Tested algorithms for maximum performance

摘要

OpenCL in Action 是一本詳盡且實用的 OpenCL 教學書籍，旨在向開發人員展示如何建立自己的高效能應用程式。它首先介紹了 OpenCL 的核心概念，包括向量運算、並行程式設計和多執行緒操作，然後逐步引導讀者從簡單的資料結構到複雜的函數。


關於這項技術

無論您使用的是什麼系統，它可能具有比您實際使用的更多的原始處理能力。OpenCL 是一種高效能的程式語言，通過在 CPU、圖形處理器和其他數據運算設備上執行來最大化計算能力。它非常適合於速度敏感的任務，如向量運算、矩陣操作和圖形加速。


關於本書

OpenCL in Action 將並行計算的理論與使用 OpenCL 建立高效能應用程式的實際情況相結合。它首先以直觀的方式引導讀者了解基本的資料結構，然後解釋了高速排序、影像處理、矩陣操作和快速傅立葉轉換等技術。本書最後深入探討了重要的圖形加速主題。豐富的挑戰性範例提供了不同的實驗方式，讓讀者可以嘗試不同的工作程式碼。

具備 C 或 C++ 背景會有所幫助，但不需要先前接觸過 OpenCL。
