| Abstract: | The subjects and key questions faced by computational astrophysics using N-body simulations are discussed in the fields of globular star cluster dynamics, galactic nuclei and cosmological structure formation. After a comparison of the relevance of different N-body algorithms a new concept for a more flexible customized special purpose computer based on a combination of GRAPE and FPGA is proposed. It is an ideal machine for all kinds of N-body simulations using neighbour schemes, as the Ahmad-Cohen direct N-body codes and smoothed particle hydrodynamics for systems including gas. |
