【摘要】 为了隐藏IO和通信延迟进而提升克希霍夫积分叠前时间偏移并行模式的性能,采用了一种流水线改进方法.针对某克希霍夫叠前时间偏移并行模式实例,提出了2种基于该改进方法的原型的设计与实现,从而提高了该实例性能.通过对典型偏移作业实验结果的分析,验证了该方法的有效性.更多还原

【Abstract】 In order to hide IO and communication latency and to improve performance of Kirchhoff prestack time migration parallel pattern, an enhanced method through pipelining is adopted. An implementation of Kirchhoff prestack time migration output parallel pattern is studied. The design and implementation of two prototypes based on the pipelining method are presented. The results show that the method can improve the performance effectively.更多还原
