摘要

摘要

En 中文
本文针对多节点多GPU分布式计算架构,提出了用于SAR层析成像中单散射体检测的多层次并行算法。考虑到本文所考虑的基于广义似然比检验的标准处理方案的计算结构,采用适当的问题分解方法,设计并制定了一种适用于异构高性能计算平台的并行算法,从而能够分层利用包括分布式和共享内存模型在内的不同层次的并行性。在配备GPU的多节点HPC集群上,使用高分辨率SAR数据集进行的实验评估展示了显著的加速效果和可扩展性。这些结果定量证实了所提出的多层次并行框架的有效性,并将所开发的原型定位为大规模SAR层析成像处理应用的一个有前景的可扩展解决方案。这对于即将到来的SAR任务尤为重要,这些任务预计将产生前所未有的数据量,从而需要可扩展和高性能的处理方案。
