Query: N-body Simulations of the Solar System with CPU-based Parallel Methods   The gravitational N-body simulation in the Solar system was performed using
different parallel approaches with the comparisons in the computational times
and speed-up values being carried out under different model sizes and the
number of processors. The numerical integration used is a second-order velocity
Verlet approach which gives the acceptable accuracy in the orbits of major
bodies and asteroids with a time step size of 0.1 days.
