This paper from Siggraph 2005 on GPU Shading and Rendering describes the Ashli shader compiler an advanced shading language interface tool from ATI that streamlines and maps arbitrary complex shaders (Renderman, OpenGL Shading Language, HLSL) onto graphics shading hardware. The shading compiler improves interfaces to the rendering sub system, tones down shading language differences (e.g. compiling HLSL bound Effect to OpenGL ARB Fragment Program), can partition shaderd across GPUs, and the remaps GPU processors. There is also a companion slide show.
