Hands-On GPU Computing with Python

By: Avimanyu Bandyopadhyay

Overview of this book

GPUs are proving to be excellent general purpose-parallel computing solutions for high-performance tasks such as deep learning and scientific computing. This book will be your guide to getting started with GPU computing. It begins by introducing GPU computing and explaining the GPU architecture and programming models. You will learn, by example, how to perform GPU programming with Python, and look at using integrations such as PyCUDA, PyOpenCL, CuPy, and Numba with Anaconda for various tasks such as machine learning and data mining. In addition to this, you will get to grips with GPU workflows, management, and deployment using modern containerization solutions. Toward the end of the book, you will get familiar with the principles of distributed computing for training machine learning models and enhancing efficiency and performance. By the end of this book, you will be able to set up a GPU ecosystem for running complex applications and data models that demand great processing capabilities, and be able to efficiently manage memory to compute your application effectively and quickly.

Summary

In this chapter, the general syntax of HIP and OpenCL code was explained with documented examples. The steps to install PyOpenCL with or without Anaconda were illustrated within an existing NVIDIA or AMD OpenCL environment. The configuration measures to set up PyOpenCL were explained step by step, we learned how computing works in Python, and the significance of computational problem solving was highlighted. With a comparison of PyOpenCL, HIP, and OpenCL, the concept of parallel reduction was revisited.

Now that this chapter is at its end, you should now be able to test your own HIP or OpenCL program. You should also be able to install and configure PyOpenCL within an existing OpenCL environment. Porting your own CUDA code to a cross-platform HIP format that can be run on both NVIDIA and AMD GPUs will also be very convenient from now on. You can now start experimenting...
