Introduction

Welcome to the world of CUDA programming! As GPUs become more central to high-performance computing, learning CUDA is essential for anyone interested in parallel processing. Whether you’re diving into AI, data science, or game development, understanding how to harness GPU power will set you apart. Each chapter of this guide is detailed in my GitHub repository, complete with code examples and diagrams to make learning easier.

Chapter 1: Basics of CUDA Programming

Let’s start with the fundamentals! In this chapter, you’ll explore the core concepts of CUDA and GPU architecture. To make things clearer, check out the GPU Architecture Diagram, which visually breaks down how GPUs manage parallel tasks. This is your foundation for everything CUDA. Explore Chapter 1 on GitHub

Chapter 2: Basic Syntax

Next, we move on to CUDA’s syntax. This chapter covers the CUDA C/C++ extensions, helping you write your first CUDA programs. Curious about how CUDA divides tasks? The CUDA Parallel Processing Diagram will help you visualize how threads and blocks work together to maximize efficiency. Dive into Chapter 2 on GitHub

Chapter 3: Simple CUDA Vector Addition

Now it’s time for some hands-on coding! This chapter guides you through a vector addition project, a fundamental example of parallel processing. The CUDA Programming Process Flowchart will be your go-to visual for understanding the overall workflow, from memory allocation to kernel execution. Check out Chapter 3 on GitHub

Chapter 4: Intermediate Algorithms

Ready for a challenge? This chapter dives into more complex algorithms like parallel reduction and matrix multiplication. You’ll learn how to optimize your code and manage memory effectively, essential skills for any serious CUDA programmer. Explore Chapter 4 on GitHub

Chapter 5: Debugging and Profiling

No coding journey is complete without debugging. This chapter covers tools like NVIDIA Nsight for profiling and optimizing your CUDA applications. Learn how to spot bottlenecks and ensure your programs run at peak performance. Discover Chapter 5 on GitHub

Unleash the Power of Parallel Processing: Your CUDA Adventure Begins!
