The multiple-relaxation-time lattice Boltzmann method is a computational method based on kinetic description of fluid mechanics. This article proposes the hybrid MPI/OpenMP parallel model based on the multiple-relaxation-time lattice Boltzmann method combined with large-eddy simulation and curved boundary treatment. By the numerical experiments in the cluster of Shanghai University-"Ziqiang 4000", the presented hybrid parallel model has better scalability on two thousands computing cores.
