Parallel Numerical Simulation for the Multi-group Particle Transport Equations
In the conditions of high temperature and high pressure,the unknown particle fluxes of transport equations were defined in energy,time,velocity phase-space and high dimensions geometry space.This paper presents an effective way to implement the scalable parallel numerical simulation on the clusters by combining the energy groups and the space domain decomposition.Based on the list schedule we first design a multi-group parallel method to solve the load unbalance problem.Then we present a parallel algorithm based on geometry domain decomposition.Experiments indicate that the algorithms get a better parallel efficiency.A parallel code combining those two algorithms was designed.Using the code,we solved a two dimension particle transport equations on a cluster,and the results show that the algorithms have well scalability.Parallel efficiency relative to 256 is 82% on 2048 processors.
