No, it's designed to be portable to all GPU hardware that can support compute, which these days is a pretty good chunk of the fleet. I tested it on Linux on Intel HD 4000, and the master branch seems to run just fine, though previous versions. A lot of the academic literature (Massively Parallel Vector Graphics, the Li et al scanline work) is dependent on CUDA, but that's just because tools for doing compute on general purpose graphics APIs are so primitive. I have a talk and a bunch of blog posts on exactly this topic, as I had to explore deeply to figure it out.
