How can I tell which NVIDIA GPUs will have P2P access to the same GPU on PCIe?

Hi,

A quote from Robert here:

" Note that in general, P2P support may vary by GPU or GPU family. The ability to run P2P on one GPU type or GPU family does not necessarily indicate it will work on another GPU type or family, even in the same system/setup. The final determinant of GPU P2P support are the tools provided that query the runtime via cudaDeviceCanAccessPeer. P2P support can vary by system and other factors as well. No statements made here are a guarantee of P2P support for any particular GPU in any particular setup."
