We have developed PVM- and MPI- parallelized versions of a space plasma
particle simulation code ``KEMPO1''. Performance evaluation on five
parallel computers is reported in this paper.
One of our goal is to solve the Electrostatic Solitary Wave (ESW) problem
by intensive computer simulations, which previously took about 1 month for
a single trial (10^7 particles, 10^4 time steps). Now that a bigger
(2.7 * 10^8 particles, 1.6 * 10^4 time steps)
calculation can be done in about 8 hours
on our 256-PU SR2201 parallel computer. It makes realistic and systematic
space plasma particle simulations feasible.
