Channel in global memory

Is it possible to create a channel in global (off-chip) memory?

You may be able to create your own FIFO in global memory with a global array and two scalars indices--front and back--defined at program scope. Then you could use the atomic integer functions to manipulate the front and back indices as needed.

How would these program-scope indices be implemented? Would atomic functions be costly on them? I'm not interested in an off-chip FIFO, but just wondering...
