On Distributed Parallelization Strategies for Particle-in-Fourier Schemes
Sriramkrishnan Muralikrishnan, Paul Fischill, Andreas Adelmann +1
We present and compare distributed parallelization strategies for the particle-in-Fourier (PIF) schemes used in kinetic plasma simulations. The different strategies are i) domain d…
A Performance-Portable, Massively Parallel Distributed Nonuniform FFT
Paul Fischill, Andreas Adelmann, Sriramkrishnan Muralikrishnan
The nonuniform fast Fourier transform (NUFFT) enables spectral methods for problems with irregularly spaced samples, with applications in medical imaging, molecular dynamics, and k…
A Comparison of Massively Parallel Performance Portable Particle-in-Cell schemes for electrostatic kinetic plasma simulations
Sonali Mayani, Paul Fischill, Sriramkrishnan Muralikrishnan +1
We compare different Poisson solvers within the context of an electrostatic Vlasov-Poisson system. These schemes are implemented as part of the IPPL (Independent Parallel Particle…
