 note = {In this paper, we describe the implementation of gravitational force calculation for N-body simulations in the context of Astrophysics. It will describe high performance implementations on general purpose processors, GPUs, and FPGAs, and compare them using a number of criteria including speed performance, power efficiency and cost of development. These results show that, for gravitational force calculation and many-body simulations in general, GPUs are very competitive in terms of performance and performance per dollar figures, whereas FPGAs are competitive in terms of performance per Watt figures., 2009 NASA/ESA Conference on Adaptive Hardware and Systems (AHS) : San Francisco, CA, USA, 2009.07.29-2009.08.1, 2009 NASA/ESA Conference on Adaptive Hardware and Systems, pp.447-452; 2009},
