In an age where data is growing exponentially and performance demands are ever-increasing, parallel computing has become essential. From rendering graphics in real-time to simulating complex physical systems and training deep learning models, the ability to perform computations across hundreds or thousands of cores simultaneously has transformed the way we approach large-scale problems. With the rise of WebGPU and its native shading language, WGSL (WebGPU Shading Language), the potential to harness the power of modern GPUs is no longer limited to desktop or server-based applications. Now, it is accessible directly through the browser, ushering in a new era of web-based high-performance computing. This book on computing is written to guide you through the exciting and rapidly evolving landscape of parallel GPU computing. Whether you are a developer seeking to optimize your applications, a researcher looking to accelerate simulations, or a student eager to learn about cutting-edge technology, this book will provide a solid foundation for leveraging the immense computational power of the GPU using WebGPU and WGSL. The choice of WebGPU as the focus is deliberate. Unlike legacy APIs, WebGPU is designed for modern workloads and offers cross-platform support across browsers. WGSL, as a shading language tailored for WebGPU, provides an elegant and intuitive syntax for both compute and graphics programming, making it a natural choice for those looking to build high-performance web applications. By using these tools, developers can now build complex compute shaders that run directly in the browser, without the need for plugins or native apps. Throughout this book, you will embark on a journey from understanding the basics of GPU architecture and parallel computing to writing advanced compute shaders for large-scale simulations, real-time rendering, and even machine learning. The content has been carefully structured to build your knowledge step by step, combining theoretical insights with practical, hands-on examples. You'll learn not just how to write compute shaders, but also how to optimize them for performance, ensuring that you can fully unlock the potential of the GPU. At the heart of this text is the goal of demystifying parallel computing and making it accessible to a broader audience. WebGPU and WGSL provide an unprecedented opportunity to democratize high-performance computing, bringing it from specialized environments into everyday use on the web. By mastering these tools, you will not only be able to tackle today's challenges but also be prepared to meet the demands of tomorrow.
Whether you're a beginner looking to learn the basics or an experienced professional seeking advanced knowledge, this book has something valuable to offer.
