The Analysis of the Efficiency of Parallelization of Existing Serial Code on the Basis of Seismic Migration
Seismic migration is the most important procedure in hydrocarbons prospecting and is aimed to correct reconstruction of underground structure. It is one of the most complicated and time−consuming task of whole seismic processing chain. Many types of seismic migration algorithms were created and implemented in both commercial and free software. One of the most important of free and open seismic procedure packages is “Seismic Un*x”. Many possible solutions of migration problems are available in this widely used system, unfortunately most of them were written as a serial codes. Authors focused on one of the serial migration code−time–wavenumber (T-K) domain migration for common–midpoint stacked data−and made an attempt of parallelization of existing code.
