Overview of this book

<p>Compute Unified Device Architecture (CUDA) is NVIDIA's GPU computing platform and application programming interface. It's designed to work with programming languages such as C, C++, and Python. With CUDA, you can leverage a GPU's parallel computing power for a range of high-performance computing applications in the fields of science, healthcare, and deep learning. </p><p> </p><p>Learn CUDA Programming will help you learn GPU parallel programming and understand its modern applications. In this book, you'll discover CUDA programming approaches for modern GPU architectures. You'll not only be guided through GPU features, tools, and APIs, you'll also learn how to analyze performance with sample parallel programming algorithms. This book will help you optimize the performance of your apps by giving insights into CUDA programming platforms with various libraries, compiler directives (OpenACC), and other languages. As you progress, you'll learn how additional computing power can be generated using multiple GPUs in a box or in multiple boxes. Finally, you'll explore how CUDA accelerates deep learning algorithms, including convolutional neural networks (CNNs) and recurrent neural networks (RNNs). </p><p> </p><p>By the end of this CUDA book, you'll be equipped with the skills you need to integrate the power of GPU computing in your applications.</p>

Profiling focused target ranges in GPU applications

NVIDIA's Visual Profiler is a handy tool for finding bottlenecks in GPU applications and understanding their operations. Although it provides fluent information of the application operations, those can be redundant if you just want to focus on a specific area of code. In this situation, limiting the range of profiling is more productive.

Profiling targets can be specific code blocks, GPU, and time. Specifying the code blocks is called focused profiling. This technique is useful when you want to focus on profiling on a specific kernel function, or profiling on the part of a large GPU application. Targeting GPUs or time will be covered after we cover focused profiling.
