Metaprogramming GPUs with Sh

Sh is an open-source system that lets you program CPUs using C++. Sh programs run on the GPU, but act like extensions of the host application. Sh can be used for defining shaders, for implementing complex multipass algorithms, or for general-purpose computation on CPUs. Sh can also be used for structured dynamic code generation for the host CPU.

This book presents Sh and demonstrates the application of the data abstraction and modularity features of C++ to the organization of shaders and stream kernels.

Using Sh you can:

• Implement your entire application in C++
• Run Sh operations on either the GPU or CPU
• Generate variants of shaders using metaprogramming
• Generate shaders from data files read at runtime
• Specialize and combine shaders
• Use classes to organize shader code

Readers should be able to start writing advanced, modular shaders and stream functions using Sh within a day.

Inside you'll find:

• A tutorial introduction to Sh
• An Sh reference manual
• A guide to the internals of Sh
