The subjects and key questions faced by computational astrophysics using N-body simulations are discussed in the fields of globular star cluster dynamics and galactic nuclei, with the focus of interest centered to the so-called ``exact'' or Aarseth-type collisional N-body simulations. Various algorithms are briefly described. A new concept for a more flexible customized special purpose computer based on a combination of GRAPE and FPGA special-purpose hardware 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.
