Ah, yeah. I see what you're saying. That is more of an open vs proprietary platform problem.

I am fairly sure that nVidia intentionally wants to keep addressable memory as a feature only for CUDA (among many other features).

Having CUDA be far superior to other shader code methods is good for vendor lock-in to their hardware, their software, their drivers, etc.

It is really sad seeing that the addressing is possible, but they won't open it up to everyone.
