Composition Computation of Radiation Hydrodynamics and Particle Transport Based on JASMIN
Xiaolin Cao · Jisuan wuli · 2012
With support of Federation Computing in JASMIN,two serial codes named radiation hydrodynamics code RH2D and particle transport code Sn2D as Federal members are concatenated to an integrated program RHSn2D,which uses efficiently thousands of processors to simulate a multiphysics composition system.Federal members of RHSn2D have mesh patches and parallel algorithms respectively,encapsulating parallel communication between them based on JASMIN.For a typical model discretized by 90 720 meshes,100 patches in RH2D,2 835 patches in Sn2D,48 directions and 16 energy groups,it shows that the integrated program RHSn2D achieves parallel efficiency of 36% with 1 024 processors.
