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>

Additional tricks

In this section, we will cover some additional topics that will help us understand the additional characteristics of the multi-GPU system.

Benchmarking an existing system with an InfiniBand network card

Different benchmarks are available for testing the RDMA feature. One such benchmark for the InfiniBand adapter can be found at https://www.openfabrics.org/. You can test your bandwidth by executing the following code:

$ git clone git://git.openfabrics.org/~grockah/perftest.git
$ cd perftest
$ ./autogen.sh
$ export CUDA_H_PATH=<<Path to cuda.h>>
$ ./configure –prefix=$HOME/test
$ make all install

 Then, you can run the following commands to test the bandwidth:

For example host to GPU memory...
