Thanks for your work on CUDA, it's really a great tool! My one hope is that Nvidia decides to make it a direct competitor to OpenCL by allowing it to target different platforms (though I recognize that it's not completely up to Nvidia and requires cooperation from others).

What would be the value in competing with OpenCL? CUDA and OpenCL ship pretty much an identical feature set with small changes in the API. The biggest difference is that OpenCL requires you to use buffers+offsets where CUDA allows "pointers" to GPU memory.

It's nice that Nvidia has CUDA so they can go ahead and expose functionality in new GPU's without having to (first) deal with OpenCL standardization. However, for the long term, it would be better if we'd stick to OpenCL so at least parts of source code can be shared between CPU's and GPU's of different vendors.

Competition is a good thing, and CUDA isn't a direct competitor to OpenCL because it only targets Nvidia's platform. OpenCL is obviously the longterm winner because nobody in their right mind would want to lock themselves into a single vendor. I'm saying that I would appreciate it for Nvidia to challenge that, which will drive both CUDA and OpenCL to become better.
