Cross fire and memory bandwidth!

Hi!

When connecting two GPUs in to cross-fire setup, how is that setup leveraged by the Open CL driver? Are the two devices visible as one? Do they share their GPU memory? Can I expect that when running a kernel on a cross-fire device, that the memory bandwidth will be doubled for that algorithm without thinking where and how to allocate the buffer?

Thanks!
