The authors have designed and built WINE-1, a special-purpose computer based on the Ewald method. The Ewald method is used to calculate long-range interparticle interactions such as the Coulomb interaction, or the gravitational interaction. It is connected to a host computer via a VME bus, WINE-1 is one board, 38 cm by 40 cm, on which 31 LSI chips and 46 IC chips are wire-wrapped. The peak speed of WINE-1 is equivalent to 480 MFLOPS. Interactions in the real space are calculated using the GRAPE system, another special-purpose computer for the direct calculation of interparticle force. Using the GRAPE-2A/WINE-1 system, for example, one can perform a molecular dynamics simulation for 10000 atoms, or a cosmological N-body simulation for 80000 bodies within a week.
