| 摘 要： | §1.引言 在激光腔靶耦合的数值模拟中,激光的传播与吸收是十分重要的部分之一。为了得到高效的激光聚变,激光入射的排布设计有一环,两环,三环激光。图1为两环激光与腔靶耦合的示意图。用LARED-H进行腔靶计算,一环光路(500根光线)时,在一个时间步长上,光路部分占总计算时间的一半左右,三环光路(1500根光线)时,光路部分占总计算时间的

| Abstract: | For the ray trace in the code of LARED-H(laser radiation election dynamic holehurm),we describe the parallelization techniques for many kinds of loop structure. We also point out some skills one should pay attention to in programming codes. The numerical result for parallel code is identical to that of the serial code. When the computing scale is fixed and the number of CPU is limited, speedup inceases linearly on the whole in pace with growth of CPU. |
