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>

Convolution

The convolutional operation (or filtering) is another common operation in many applications, especially in image and signal processing, as well as deep learning. Although this operation is based on the product of sequential data from the input and filter, we have a different approach for matrix multiplication.

Convolution operation in CUDA

The convolutional operation consists of source data and a filter. The filter is also known as a kernel. By applying the filter against the input data, we can obtain the modified result. A two-dimensional convolution is shown in the following diagram:

We need to consider a couple of concepts when we implement convolution operation, that is, kernel and padding. The kernel is...
