Abstract: Invariable processor in a minimum federal algorithm is applied to RHSn2D program,which is a multi-physics composition program such as radiation hydrodynamics and particle transport based on parallel software infrastructure JASMIN. With improvement of parallel algorithm,RHSn2D program achieves parallel efficiency of 16% with 8192 processors for real models. Time analysis of integrated program demonstrates that perfermance of MPI collective communications in parallel software infrastructure decides computing time of radiation hydrodynamics with parallel algorithm.
