Abstract

Seismic modelling to produce realistic seismic traces is a computationally intensive problem. A 2D synthetic wave propagation code using explicit finite differences with absorbing boundary conditions has been implemented on an Intel Hypercube with 32 processors. The algorithm is highly parallel with good load balancing between processors and speed up proportional to the number of processors being used. A vectorised version of the code has been used to evaluate the performance of the Intel IPSC-VX 5d vector hypercube. Mflop rates up to 71 are achieved.
地震模拟用矢量超立方体的评价
地震建模以产生真实的地震道是一个计算量很大的问题。在32处理器的Intel Hypercube上实现了一种利用显式有限差分和吸收边界条件的二维合成波传播代码。该算法具有高度并行性,处理器之间具有良好的负载平衡,并且速度与使用的处理器数量成正比。该代码的矢量化版本已被用于评估英特尔IPSC-VX 5d矢量超立方体的性能。Mflop率高达71。
