GLSL shaders themselves are simply a set of strings that are passed to the hardware vendor's driver for compilation from within an application using the OpenGL API's entry points. Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string.
shader-db is a collection of about 20,000 shaders gathered from various computer games and benchmarks as well as some scripts to compile these and collect some statistics. Shader-db is intended to help validate an optimization. It was noticed that an unexpected number of shaders are not hand-written but generated.
OpenGL (Open Graphics Library [4]) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.
The High-Level Shader Language [1] or High-Level Shading Language [2] (HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to become the required shading language for the unified shader model of Direct3D 10 and higher.
Shader Model 2.0b — Radeon X700-X850 shader model, DirectX 9.0b. Shader Model 3.0 — Radeon X1000 and GeForce 6, DirectX 9.0c. Shader Model 4.0 — Radeon HD 2000 and GeForce 8, DirectX 10. Shader Model 4.1 — Radeon HD 3000 and GeForce 200, DirectX 10.1. Shader Model 5.0 — Radeon HD 5000 and GeForce 400, DirectX 11.
The new driver model requires the graphics hardware to have Shader Model 2.0 support at least, since the fixed function pipeline is now translated to 2.0 shaders. However, according to Microsoft as of 2009, only about 1–2 percent of the hardware running Windows Vista used the XDDM, [10] with the rest already WDDM

The unified shader model uses the same hardware resources for both vertex and fragment processing. In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities.
