John, thank you for your reply. It was the update of the Stream SDK that guided me to your site, indeed. I also understood the AMD Core Math Library to be a prime candidate. When thinking about build dependencies, it may also be the Open64 compiler suite, something from the GPU developer tools, possibly?
However, I feel that you may gain most from a better availability of your developments to the regular programmer, who is just already very busy and overworked and does not want to distract himself too much with technical bits but knows at the same time to need further education all the time.
If you could arrange for some blog-like entries with some code snipplets or smallish howtos to introduce to your technoogies, and if those are practically directly executable since they install via apt-get/rpm, then you reach many more hearts than you can today. This could be as simple as a pointer to some code that your compiler can do much better than gcc, or be something really surprising.
So, please start with the Stream SDK, go via math and you should get back more from the community than just better sales figures.
