Abstract:
A parallel algorithm for solving the unsteady 3D problems of collisionless
dynamics in the case of more than $10^9$ bodies in a self-consistent
gravitational field in Cartesian coordinates is proposed. The algorithm is
based on the computational domain decomposition method. The parallel code
that implements this algorithm can be used to perform computations on
grids of more than $1000^3$ nodes. Some results of supercomputer simulation
obtained by the code are discussed.
