Abstract

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.

0 (N^2)重力N体仿真中ASIC、fpga、gpu和通用处理器的比较研究

在本文中，我们描述了在天体物理学背景下n体模拟重力计算的实现。它将描述在通用处理器、gpu和fpga上的高性能实现，并使用包括速度性能、功率效率和开发成本在内的许多标准对它们进行比较。这些结果表明，对于引力计算和一般的多体模拟，gpu在性能和每美元数字的性能方面非常有竞争力，而fpga在每瓦特数字的性能方面具有竞争力。
