How to zero-copy

Accelerated Computing CUDA CUDA Programming and Performance

Perhaps I’m supposed to find this easily, but I’m not sure where. The 2.2 programming guide doesn’t mention zero-copy at all.

How do I use it?
Which GPU do I need?

Look for “mapped memory” in the CUDA 2.2 guide and you should find what you are looking for. AFAIK the GTX200 series (plus Telsa C1060 and S1070), and the MCP79 integrated graphics chipset are the only GPUs which support it at the moment.

The whole series is very good.
