Will GPGPU add virtual-memory support?

[VirtualLarry]

Just wondering, if perhaps, in order to easier support certain GPGPU workloads, if they will implement a virtual-memory system? And if they do, if that will cause a fracture between the GPGPU and regular GPU camps, as adding a level of memory indirection will likely cause severe slowdowns when used for regular graphics rendering.

I'd imagine it's on the way. When it comes to graphics, DirectX10/WDDM already do something similar, and WDDM 2 was supposed to take it all the way with per-process virtual memory.

If the graphics workload fits in physical memory, why would it cause a slowdown?

When is WDDM 2 coming out? 7 is WDDM 1.1.

I have no idea, and I doubt MS does either. They were talking about WDDM 2 before Vista even launched. If I had to take a guess, something that will be called WDDM 2 will launch with whatever OS follows Win7.
