Hello Szilard:

   thanks for kind comments. If there are not so much people use openMM, 
probably you can consider give it up. Currently I am using NVIDIA GTX590 
GPU acceleration with Gromacs4.6 without openMM support, and it works 
fine (I did some tests comparing with CPU running results for my 
system). If I were you, I will save my time and energy focus on current 
version and road.

I am asking if it support ATI just because I've got a stupid MAC Pro 
machine these days, and it claimed to have a very good ATI GPU, so I 
just wondering if it could support ATI GPU accelerations. It since that, 
almost all MD tools only support NVIDIA GPU.....
