Abstract

Abstract: Unbalanced Stiff equations are used to simulate the nonequilibrium phenomena of radiation.The parallelism of the numerical computation is analyzed and a kind of load balancing method is given.In order to increase the data locality, a sequencing computation method in multi-processors is also given.With the corresponding parallel algorithm of the simulation,the results testified on the workstations are provided and discussed.

Key words: Stiff equations, unbalanced phenomena, parallel computation
