| Abstract: |
| Because of the first principles and fewer assumptions， the particle simulation can well preserve various nonlinear physical process properties of electric propulsion devices. However， the computational burden is great， and parallel computing is an effective method to reduce the computation time. The state-to-art status of domestic and international research on the parallel computing is summarized in this paper. The computer implementation of parallel computing in particle simulations is analyzed and the basic knowledge of parallel computing is introduced. The key technical issues in parallel computing， i.e.， parallel algorithms of particle advances， solving methods of electromagnetic field， and computational load balancing， are figured out. Finally， a summary is made to outlook the parallel computing methods in electric propulsion devices. |
