Some Aspects of Parallel Performance of a Seismic Ray Analysis Algorithm

We consider the reconstruction of the velocity structure from measurements of travel times of seismic surface waves. The main problem is reduced to finding solution of a system of linear inequalities in infinite-dimensional space. The solution process is based on a combination of parallelized versions of the Backus–Gilbert and the constraint aggregation methods. The experimental results obtained on the IBM SP parallel computer are presented and analyzed.
