I see you have the forward function to render out "color" given the properties of the stars that contribute to this region in space. All you have to do is find the highest probable property values that would generate that set of pixels. Sounds extremely parallizable which is probably why you managed to get the most out of the xeon phi.

It's not quite that easy because of a) the noise (you're fitting distributions not values) and b) the fact that multiple light sources affect a given pixel, so you have to be a bit clever. But yes, you can get parallelism by spatial partition.
