基于C++AMP并行加速的三维弹性波波动方程数值模拟
Accelerated parallelism in numerical simulation for 3D elastic wave equation with C++AMP
摘要
Abstract
Seismic forward numerical simulations have extensive applications in the inversions and the geometry design.This paper introduces the parallel simulation of the memory/computing-intensive and large-scale 3D elastic wave equation with C++AMP.C++AMP is Mierosoft's technology for accelerating C++applications by allowing code run on data-parallel hardware like graphic-processing units(GPUs).On the basis of research on parallel algorithm with C+ + AMP,we compared it with CPU serial algorithms and OpenMP.The results of numerical experiment demonstrate the effectiveness and portability of this method.Furthermore,C++AMP has a good portability on windows platform because the same executable can run on NVIDIA and AMD devices.It can significantly improve develop efficiency.关键词
