Directx11d3d compute shader is dedicated for gpgpu. The highlevel shader language or highlevel shading language 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 hlsl is analogous to the glsl shading language used with the opengl standard. Typically, a hardware implementation runs a pixel shader on multiple pixels for example a 2x2 grid simultaneously, so that derivatives of quantities computed in the pixel shader can be reasonably approximated as deltas of the values at the same point of execution in adjacent pixels. Instead, a compute shader must be configured as the only stage of a compute pipeline. Announcment of wpf pixel shader effects library contains some links at the bottom.
