| Research Abstract |
We study numerical schemes for the first-principle Vlasov code as a second-next-generation computer simulation technique of space plasma. We developed numerical algorithms for solving the collisionless Boltzmann (Vlasov) equation which is a hyper-dimensional conservation law. The new simulation code is parallelized for scalar massively parallel computers and has achieved more than 80% parallel efficiency on more than 1,000 CPU cores. The new code is applied to various multi-scale processes in space plasma. The numerical results imply the existence of cross-scale coupling between fluid scale and particle scale.
