并行编程与OpenACC是实现可靠的计算系统的现代实用指南。这本书解释了任何人都可以如何使用OpenACC使用称为pragmas的高级代码指令来快速提高应用程序的性能。OpenACC基于指令的编程模型旨在提供一种简单但功能强大的加速器方法，而无需进行大量编程工作。作者Rob Farber与一组专家贡献者合作，演示了如何将现有应用程序转换为可移植的GPU加速程序，并演示了立即加速。这本书还帮助用户从最新的NVIDIA和AMD GPU和多核CPU架构（以及很快为Intel Xeon Phi）中获得最大的好处。可下载的示例代码为科学、商业、大数据和实时系统中的常见问题提供了实际操作的OpenACC经验。主题包括编写可重用代码、异步功能、使用库、多核集群等等。每一章都解释了OpenACC技术的特定方面，它是如何工作的，以及要避免的陷阱。在整个过程中，本书演示了如何使用简单的工作示例，可以适应解决应用程序的需求。介绍了利用gpu实现应用程序加速的最简单方法，展示了OpenACC是如何工作的，包括可以适应应用程序需求的工作示例。允许读者从本书的配套网页下载源代码和幻灯片
Parallel Programming with OpenACC is a modern, practical guide to implementing dependable computing systems. The book explains how anyone can use OpenACC to quickly ramp-up application performance using high-level code directives called pragmas. The OpenACC directive-based programming model is designed to provide a simple, yet powerful, approach to accelerators without significant programming effort. Author Rob Farber, working with a team of expert contributors, demonstrates how to turn existing applications into portable GPU accelerated programs that demonstrate immediate speedups. The book also helps users get the most from the latest NVIDIA and AMD GPU plus multicore CPU architectures (and soon for Intel Xeon Phi as well). Downloadable example codes provide hands-on OpenACC experience for common problems in scientific, commercial, big-data, and real-time systems. Topics include writing reusable code, asynchronous capabilities, using libraries, multicore clusters, and much more. Each chapter explains how a specific aspect of OpenACC technology fits, how it works, and the pitfalls to avoid. Throughout, the book demonstrates how the use of simple working examples that can be adapted to solve application needs. Presents the simplest way to leverage GPUs to achieve application speedups Shows how OpenACC works, including working examples that can be adapted for application needs Allows readers to download source code and slides from the book's companion web page
