    3 The gravitational many-body problem is a problem concerning the movement of bodies, which are interacting through gravity. However, solving the gravitational many-body problem with a CPU takes a lot of time due to O(N^2) computational complexity.

    44In this paper, we report our technique to speed-up the exact force-calculation on RV770 GPU from AMD/ATi. 
    55As far as we know, our implementation on RV770 GPU running at 750 MHz shows fastest
