After tinkering with the source for a bit longer, I can see that it will be very difficult to make ibniz go fast because of an inherent inter-pixel dependency in the stack. The semantics of the language seem to imply that the pixel kernel can pass information on to the next pixel via the stack. To be able to split up the rendering work that dependency needs to be eliminated such that each pixel depends only on x,y,t- and values pushed by the last run are implicitly cleared in single thread implementations. What sort of impact will that have on existing demo programs?
