Present status of computer simulation at IPP

Abstract

The computer center of the Institute of Plasma Physics installed a supercomputer, and almost all computation time is used for simulation studies of plasmas. The status of the simulation is reported. Although particle simulation codes are used to study microscopic phenomena of plasma, they contain a charge-assignment portion that cannot be vectorized because of the recurrence of data. The author proposes an algorithm to vectorize the charge-assignment routine.<>
