HailMary, good work! Keep us informed as you do more public benchmarks. :)

HM, Re: I compiled up an off-the-shelf standalone qsort c program using gcc and various targets. I sorted 100M randomly generated integers, and I used the same set of integers for each run.

What makes your app more "real world" than, say, Sandra or PCMark? Actually, I would think that PCMark is more real world, since it uses things such as compression and imaging algorithms used in many applications, while yours does nothing more than quicksort.

HailMary, what was the size of the integeres you sorted in both modes? I'd like to see a comparison between sorting 64-bit integers with 32-bit code vs. with 64-bit code.

I *think* int defaults to 32 bits in either 32 or 64-bit mode, but I'm not sure how you define a 64-bit integer in each mode, though I remember reading what compilers are supposed to do in one of the AMD64 programming manuals. (long int?)

PS, by habit I always use long instead of int when I know that I need 32 bits.
