A Multi-threaded Particle-in-cell Approach for Kinetic Plasma Simulations

Particle-in-cell (PIC) simulations for plasma physics model self-consistently plasma phenomena at kinetic scales. Such simulations focus on the individual trajectories of a very large number of particles in self-consistent and external electric and magnetic fields, and are of great importance in astrophysics and space sciences. We developed a multi-threaded application to simulate such phenomena. This article describes the parallel performance of our application on a high-performance multicore system.
