ParaPIF: A Parareal Approach for Parallel-in-Time Integration of Particle-in-Fourier schemes

ParaPIF: A Parareal Approach for Parallel-in-Time Integration of Particle-in-Fourier schemes

We propose ParaPIF, a parareal based time parallelization scheme for the particle-in-Fourier (PIF) discretization of the Vlasov-Poisson system used in kinetic plasma simulations. Our coarse propagators are based on the coarsening of the numerical discretization scheme combined with, if possible, temporal coarsening rather than coarsening of particles and/or Fourier modes, …
