Implementation of a 2D Electrostatic Particle in Cell algorithm in Uni ed Parallel C with dynamic load-balancing

Since space plasmas are colisionless, reliable space weather simulations will require to take into account a full kinetic description of their dynamics. The Particle in Cell (PIC) method is a particle-mesh technique that e ciently allows such description. Still, realistic plasma simulations require huge data sets and are computationally expensive. High scalability must thus be achieved in order to perform the massively parallel plasma simulations required for space weather purposes. This paper reports on the rst implementation of a 2D electrostatic PIC code in Uni ed Parallel C which also includes load balancing capabilities.
