摘要
在激光驱动惯性约束聚变的数值模拟中,通常使用光路追踪法来计算激光能量沉积。为了适应大规模、高效率的数值模拟需要,本文提出了分组流水线的光路追踪并行策略,能够充分提高大量光线在区域分解网格下的并行性。
In order to simulate the energy deposition in the inertial confinement fusion driven by laser, a geometric optics approximation called the ray-tracing algorithm is used in general. Because of the requirements of large-scale and efficient simulations, the parallelization of the ray-tracing algorithm is discussed. Ray-racing computation is effectively dealt with by a group-pipeline strategy which can significantly improve the parallel performance with the existing decomposition of the domain.
