Is this for the OpenCL implementation?

I know in the past I have been aware of more than a few folks that are
quite excited about the possibility of GPU enhanced calculations, but
when talking with industry folks, the concerns are with consistency of
delivery.

Does OpenCL suffer from the same inconsistencies?

Am I to assume that tiled software driven rendering is to happen
alongside of this so that the artist pipeline is able to harness the
power of GPU calculations for more immediate feedback of looks and
then software based for final consistency of rendering across all
platforms?

I'd think that tile based compositor software rendering is very high
up most people's priority list. As such, group sourced funding might
be a feasible approach.

Thanks for taking the time to respond,
