Abstract:   In order to execute various FDM applications on large-scale parallel computers with a reasonable cost of computer resources, a framework using an adaptive mesh refinement (AMR) technique has developed. AMR can realize high-resolution simulations saving computer resources by generating and removing hierarchical grids dynamically. In the AMR framework, a dynamic domain decomposition (DDD) technique as a dynamic load balancing method is also implemented to correct a computational load imbalance between each process associated with a parallelization. By performing a 3D AMR test simulation, it is confirmed that the dynamic load balancing can be achieved and the execution time is also reduced by introducing the DDD technique.
