摘要(Abstract)：

基于稀疏反演的表面多次波压制方法(EPSI)能够避免传统表面多次波压制方法对有效波的损伤,但是计算成本较高。研究基于新GPU加速策略的稀疏反演表面多次波压制方法,将所有频率成分整体导入设备端,并将中间结果存储于设备端,实现所有频率成分的同步运算,并减少主机端和设备端的数据传输时间。SMAART模型测试结果表明:基于新GPU加速策略的EPSI方法的计算效率较常规EPSI方法的提升11倍,较基于传统GPU加速策略的EPSI方法的提升4倍。基于新的GPU加速策略的稀疏反演表面多次波压制方法正确有效,计算效率更高。

关键词(KeyWords)：GPU加速策略;稀疏反演;地震数据传输;表面多次波;计算成本
