We present a fast parallel scheme to speed up 3D wave‐equation depth migration on a parallel computing device, Graphics Processing Units (GPUs). The third‐order generalized‐screen propagator is employed to take advantage of the built‐in software implementation of fast Fourier transform. We minimize the low‐bandwidth data transfer by storing the 3D velocity model and imaged data in device memory. We reduce half of the memory demand by compressing the 3D velocity model and imaged data using integer arrays instead of float arrays. A 2D tapered function is suggested for boundary conditions, which is more suitable for the parallel implementation on the GPU than the commonly‐used 1D one. Both three‐dimensional impulse responses and synthetic data examples demonstrate that the proposed GPU‐based Fourier migration is typically 25 to 40 times faster than the CPU‐based implementation. It enables us to build the macro velocity model in a much shorter turnaround time.Permalink: https://doi.org/10.1190/1.3255481FiguresReferencesRelatedDetailsCited ByGPU-Based Large Seismic Data Parallel CompressionGPU-Based Multi-resolution Volume Rendering for Large Seismic DataLeveraging graphics processing units (GPUs) for real-time seismic interpretationThe Leading Edge, Vol. 29, No. 1 SEG Technical Program Expanded Abstracts 2009ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2009 Pages: 4338 publication data© 2009 Copyright © 2009 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 14 Oct 2009 CITATION INFORMATION Shu‐Qin Wang, Jin‐Hai Zhang, and Zhen‐Xing Yao, (2009), "Accelerating 3D Fourier migration on graphics processing units," SEG Technical Program Expanded Abstracts : 3020-3024. https://doi.org/10.1190/1.3255481 Plain-Language Summary PDF DownloadLoading ...
