Evaluation of a vector hypercube for seismic modelling

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.
