Rahul Garg's MSc thesis sounds interesting
Is it online available?
Where can i find it?
Currently have applied for an MSc myself for something similar, would be curious to know if any assistance would be issued too.
Myself and other engineers monitor these forums along with beyond3D and a couple other forums, so asking your questions here will be a good place to get assistance from AMD and from the community.
I would look at some already known benchmarks for parallel computing (not necessarily GPU computing either), some standards, and start there.
Also, from my point of view, if you are trying to compare architectures, I think it's paramount to tune the benchmarks to the specific architectures.
EDIT: There is already a TON of info in these forums regarding AMD GPU architectures.
