Supercomputer simulation of plasma electron dynamics in a magnetic trap with inverse magnetic mirrors and multipole magnetic walls

The problem of simulation of plasma electron dynamics in a magnetic trap with inverse magnetic mirrors and multipole magnetic walls is considered. The model is proposed on the basis of the particle-in-cell method. The complexity of the processes under study and a required high accuracy of results necessitate the development of a highly scalable computational algorithm. The algorithm must be capable of computing billions of particle trajectories in reasonable time. In order to achieve a uniform and complete workload of computational nodes of a supercomputer, the mixed Eulerian-Lagrangian decomposition is used. A dynamical timestep is taken into account. This approach results in a high scalability and in a significant decrease of computational time.
