this is awesome. i had no idea anything like this was coming. is there anything out else out there that confirms this? and will it extend upwards to include bulldozer too?

You can find the whole main presentation here: http://developer.amd.com/documentation/presentations/assets/... I'm presuming stuff coming from amd.com is confirmation. It should certainly include future products, what I would worry about is to what extent existing graphics cards will be able to take advantage of this.

Generally, I'd say this looks a lot like Clang but with better ways to express memory parralelism at least. No way to know at this point to what extent this will catch on, but it looks interesting.

I think it's bigger than that - the idea that a GPU can execute syscalls is pretty crazy if you really buy into it (i.e. the entire OS is running using this heterogenous environment)

This is possible now [1]. FSA will (hopefully) make it significantly more efficient.
