Abstract
The invention provides a heterogeneous parallel computing implementation method and device for a three-dimensional sound wave NPML algorithm, and the method comprises the following steps: determiningavailable computing equipment in a known heterogeneous computing platform, constructing a computing resources topological structure according to the available computing equipment, wherein the available computing equipment in the heterogeneous computing platform comprises CPUs, GPUs and accelerators; according to the calculation scale of a single shot in the three-dimensional sound wave NPML algorithm, computing the memory of each available computing equipment in the resource topological structure, and allocating a corresponding computing task to each available computing equipment; according tothe computing resource topological structure, enabling each available computing equipment to allocate a corresponding computing task, achieving parallel computing of the three-dimensional sound waveNPML algorithm to acquire single-shot seismic simulation record data. According to the scheme, the total simulation calculation time of a single shot is shortened, the application timeliness is enhanced, the unit time efficiency is improved, and the maximum computing capability of the heterogeneous computing platform is exerted.
Description
technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to a method and device for realizing heterogeneous parallel computing of a three-dimensional acoustic wave NPML algorithm. Background technique [0002] The 3D acoustic NPML algorithm forward modeling is an important tool for the analysis of the observation system in the design of the seismic exploration acquisition plan. Due to its large calculation workload and large amount of component data, in practical applications, the calculation time is too long and the intermediate data is too much. The requirement for computing resources is very high, which seriously affects the practical application. [0003] The realization of the existing three-dimensional acoustic wave NPML algorithm is to adopt the isomorphic computing method, that is, multi-machine CPU or multi-machine GP (Graphics Processing Unit, the processor of the graphics card is called a graphics processor). The...
