Vectorizing the interpolation routines of particle-in-cell codes

A discussion of the interpolation routines in particle-in-cell codes is presented indicating the problems in vectorizing them. Solutions to these problems are then discussed with the timing results indicating the effectiveness of the solutions. A comparison of our methods to those of Nishiguchi et al. (J. Comput. Phys. 61, 519 (1985)) is presented. Finally, multitasking is briefly addressed. copyright 1987 Academic Press, Inc.
