摘要
In order to enhance the computing efficiency of prestack time migration,this paper realizes the Kirchhoff prestack time migration process under the mode of GPU\CPU co-processing parallel computing,and optimizes it.The test on NVIDIA Tesla C1060 shows that processing on GPU is about 40 times faster than CPU(single core).It is also demonstrated that CUDA provides a convenient environment for the translation from CPU to GPU.
