Abstract
Computer simulations with the first-principle (kinetic) model are essential for studying multi-scale processes in space plasma. We develop numerical schemes for Vlasov simulations for practical use on currently-existing supercomputer systems. The weak-scaling benchmark test shows that our parallel Vlasov code achieves a high performance and a high scalability. Currently, we use more than 1000 cores for parallel computations and apply the present parallel Vlasov code to various cross-scale processes in space plasma, such as a first-principle global simulation of solar-wind-magnetosphere interactions.
