This book primarily uses Go, the Gorgonia package for Go, the Cu package for Go, CUDA (plus drivers) from NVIDIA, and an NVIDIA GPU that supports CUDA. Docker is also needed for Section 3, Pipeline, Deployment, and Beyond!

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

type nn struct {
    g *ExprGraph
    w0, w1 *Node

    pred *Node
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

intercept Ctrl+C
    sigChan := make(chan os.Signal, 1)
    signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM)
    doneChan := make(chan bool, 1)

Any command-line input or output is written as follows:

sudo apt install nvidia-390 nvidia-cuda-toolkit libcupti-dev

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
