Abstract
Parallel implementation and computational aspects of the problem of simulating dynamics of gravitating systems, in particular, a protoplanetary disc, are considered. The mathematical model of the disc involves the Vlasov-Liouville multidimensional kinetic equation, the Poisson equation, and gas dynamics equations. One of the main problems of numerical simulation of gravitational dynamics is the necessity of multiple solution of the Poisson equation. A fast parallel solver for this equation and a dynamic load balancing algorithm for processor elements are presented. They employ the physical peculiarities of the problem.
