I want to process the texture line by line in parallel. But I dun know how to program my shader program.
Shader can be used to process each vertex in parallel. But I dun understand how it works? Can anyone explain further?

Likewise, each pixel processor running your pixel shader gets to work on ONE of the output pixels -- thousands of them in each triangle.
So those programs need to written as if they're the only thing happening. In other words; you don't need to worry about the "line-by-line" thing. You only need to worry about what happens for each individual pixel.
Could you perhaps elaborate a little more on what it is you're trying to achieve?
