| 摘 要： | 基于JASMIN框架的"联邦计算",将两个串行程序辐射流体RH2D与粒子输运Sn2D作为独立"邦元"耦合连接,形成的集成程序RHSn2D可以采用数千处理器并行模拟多物理耦合问题.集成程序RHSn2D中的邦元具有各自独立的网格划分与并行算法,同时借助框架技术,可以屏蔽邦元间的并行数据传递.算例表明,对于应用问题规模(90 720个网格单元,辐射流体100个Patch,粒子输运2 835个Patch,Sn方向48,16群),集成程序RHSn2D采用1 024个处理器可以达到36%的并行效率.

| Abstract: | 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. |
