Abstract: We present Vlasiator, a novel code based on Vlasov's equation, developed for modeling magnetospheric plasma on a global scale. We have parallelized the code to petascale supercomputers with a hybrid OpenMP-MPI approach to answer the high computational cost of propagating ion distribution functions in six dimensions. The accuracy of the numerical method is demonstrated by comparing simulated wave dispersion plots to analytical results. Simulations of Earth's bow shock region were able to reproduce many well-known plasma phenomena, such as compressional magnetosonic waves in the foreshock region, and mirror mode instability in the magnetosheath.
