Abstract: In this work, we present a parallel implementation of radiation hydrodynamics coupled with particle transport, utilizing software infrastructure JASMIN (J Adaptive Structured Meshes applications INfrastructure) which encapsulates high-performance technology for the numerical simulation of complex applications. Two serial codes, radiation hydrodynamics RH2D and particle transport Sn2D, have been integrated into RHSn2D on JASMIN infrastructure, which can efficiently use thousands of processors to simulate the complex multi-physics phenomena. Moreover, the non-conforming processors strategy has ensured RHSn2D against the serious load imbalance between radiation hydrodynamics and particle transport for large scale parallel simulations. Numerical results show that RHSn2D achieves a parallel efficiency of 17.1% using 90 720 cells on 8 192 processors compared with 256 processors in the same problem.
