摘要
针对地震资料数据处理方法中的三维叠前Kirchhoff深度偏移方法,分析其特点及自动并行化特征,提出一种基于网格环境的自动并行化模型。该模型可以自动分析识别串行程序中潜在的并行性,自动完成串行三维叠前深度偏移(PSDM)程序的分割、并行重构和调度,最终生成串行PSDM程序的并行化源代码。
In allusion to the 3-D pre-stack Kirchhoff depth migration method of the seismic data processing,via analyzing its characteristic and the automatic parallelization characteristic,one kind of automatic parallelization model based on the grid environment was proposed.This model can automatically analyze and recongnize the latent parallelism of serial program.It automatically completes the division of the 3-D pre-stack Kirchhoff depth migration program,parallel restructuring,finally produces the parallelization source code of the serial PSDM procedure.
