The particle acceleration mechanism of pulsars has been an outstanding problem for more than forty years. A breakthrough can be provided by a large particle-simulation for the global magnetosphere showing the formation of the field-aligned electric field. However, this demands heavy calculation of Coulomb interaction. We have resolved this difficulty by use of GRAPE, which is a massively parallel special purpose computer for astronomical N-body problem at National Astronomical Observatory of Japan. Note that GRAPE can calculate Coulomb force as well as gravitational force because of the same inverse-square law and of sign-bit available with GRAPE. In this paper, we present a method of particle simulation for the global magnetosphere including electron-positron pair creation. We show some initial results of the simulation.
