OpenCL Programming by Example

A comprehensive guide on OpenCL programming with examples with this book and ebookKey FeaturesLearn about all of the OpenCL Architecture and major APIs.Learn OpenCL programming with simple examples from Image Processing, Pattern Recognition and Statistics with detailed code explanation.Explore several aspects of optimization techniques, with code examples to guide you through the processUnderstand how to use OpenCL in your problem domainsBook DescriptionResearch in parallel programming has been a mainstream topic for a decade, and will continue to be so for many decades to come. Many parallel programming standards and frameworks exist, but only take into account one type of hardware architecture. Today computing platforms come with many heterogeneous devices. OpenCL provides royalty free standard to program heterogeneous hardware.This guide offers you a compact coverage of all the major topics of OpenCL programming. It explains optimization techniques and strategies in-depth, using illustrative examples and also provides case studies from diverse fields. Beginners and advanced application developers will find this book very useful.Beginning with the discussion of the OpenCL models, this book explores their architectural view, programming interfaces and primitives. It slowly demystifies the process of identifying the data and task parallelism in diverse algorithms.It presents examples from different domains to show how the problems within different domains can be solved more efficiently using OpenCL. You will learn about parallel sorting, histogram generation, JPEG compression, linear and parabolic regression and k-nearest neighborhood, a clustering algorithm in pattern recognition. Following on from this, optimization strategies are explained with matrix multiplication examples. You will also learn how to do an interoperation of OpenGL and OpenCL.“OpenCL Programming by Example” explains OpenCL in the simplest possible language, which beginners will find it easy to understand. Developers and programmers from different domains who want to achieve acceleration for their applications will find this book very useful.What you will learnUnderstand OpenCL Platform Model, Execution Model, Memory Model, and Programming ModelExplore the different OpenCL objects, APIs for building kernel, memory allocation, data transfer, synchronization, and many moreGet to grips with API explanations, featuring simple examplesCreate image processing examples such as Image histogram and Image convolutionLearn optimization techniques with Matrix Multiplication and Histogram examples.Develop Bitonic sort in OpenCLBuild JPEG decoder using OpenCLConstruct linear and parabolic regression equation in OpenCLCompose k-nearest neighborhood clustering algorithm from pattern recognitionUse OpenCL with OpenGL interoperabilityWho this book is forIf you are a beginner in parallel programming and would like to quickly accelerate your algorithms using OpenCL, this book is perfect for you! You will find the diverse topics and case studies in this book interesting and informative. You will only require a good knowledge of C programming for this book, and an understanding of parallel implementations will be useful, but not necessary.
