Hands-On GPU Programming with Python and CUDA

By: Dr. Brian Tuomanen

Overview of this book

Hands-On GPU Programming with Python and CUDA hits the ground running: you’ll start by learning how to apply Amdahl’s Law, use a code profiler to identify bottlenecks in your Python code, and set up an appropriate GPU programming environment. You’ll then see how to “query” the GPU’s features and copy arrays of data to and from the GPU’s own memory. As you make your way through the book, you’ll launch code directly onto the GPU and write full blown GPU kernels and device functions in CUDA C. You’ll get to grips with profiling GPU code effectively and fully test and debug your code using Nsight IDE. Next, you’ll explore some of the more well-known NVIDIA libraries, such as cuFFT and cuBLAS. With a solid background in place, you will now apply your new-found knowledge to develop your very own GPU-based deep neural network from scratch. You’ll then explore advanced topics, such as warp shuffling, dynamic parallelism, and PTX assembly. In the final chapter, you’ll see some topics and applications related to GPU programming that you may wish to pursue, including AI, graphics, and blockchain. By the end of this book, you will be able to apply GPU programming to problems related to data science and high-performance computing.

Using the Nsight IDE for CUDA-C development and debugging

Let's now learn how to use the Nsight IDE for developing CUDA-C programs. We will see how to import the program we just wrote, and compile and debug it from within Nsight. Note that there are differences between the Windows and Linux versions of Nsight, since it is effectively a plugin of the Visual Studio IDE under Windows and in the Eclipse IDE under Linux. We will cover both in the following two subsections; feel free to skip whatever operating system does not apply to you here.

Using Nsight with Visual Studio in Windows

Open up Visual Studio, and click on File, then choose New | Project.... A window will pop up where you set the type of project: choose the...
