Abstract
Magnetic reconnection is one of the most important basic processes in plasma physics. It helps building up models for various astronomical events. Most of these events have large system size, while the diffusion region where reconnection literally happens is small due to weak diffusivity of the astronomical environment. Therefore, big simulations which integrate large system size with small diffusion region is required to approach the realistic circumstance.
