Parallel Optimization of Computational Fluid Dynamics Application Palabos Based on NextGeneration Sunway Supercomputer

Parallel lattice Boltzmann(Palabos)software is a widely used computational fluid dynamics software based on lattice Boltzmann method(LBM),which is widely used in the field of porous media,free interface,particle motion,blood flow and so on due to its excellent computing power.Palabos has a wide range of user needs,which makes it urgent to transplant,optimize and accelerate parallel on Sunway supercomputer to serve the energy and chemical industry.In this paper,the heterogeneous parallel design of Palabos software is carried out on the new generation Sunway supercomputer system(SW26010pro).The data structure and template programming of Palabos are not suitable for the heterogeneous parallel of Sunway supercomputer system.So we design the parallel optimization techniques called direct getting address,polymorphic tag processing and data slicing to deal with the Palabos data structure and template programming.Combined with the characteristics of the new generation of Sunway supercomputer system,the optimization t
