    33The 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. 
    5 As far as we know, our implementation on RV770 GPU running at 750 MHz shows fastest 
     5Our implementation on RV770 GPU running at 750 MHz shows  
    66performance of ~ 1 Tflops thanks to efficient cache architecture of RV770 GPU.  
    7 This is accomplished by a simple loop-unrolling technique that is highly effective RV770 GPU. 
     7This siginifiant performance result is fastest ever as far as we know. 
     8Our optimized result is realized by a loop-unrolling technique that is highly effective RV770 GPU.
