In your current patch, you are reusing the CPU backend machinery. Originally, we designed the backend so that you could write your own GPU backend that would chunk work in a way that makes the most sense for it (which may not be something hierarchical like we do for the CPU, where we often do a map-reduce kind of pattern). Do you have thoughts on that? Is there a reason why you went for reusing the CPU backend? Is it just because the simd pragmas currently live there and it seemed easier to do it that way?
