| Abstract: | For taking full advantage of multi-core computers and improving computing speed of coherent cube of seismic data, a coherence parallel algorithm with the research of multi-core parallel technology has been designed and implemented. The comparison test of the performance between the serial and the parallel algorithm has been completed. The result shows that using Pthread can make full use of multi-core resources and achieve an ideal linear speedup. The result also indicates that using Pthread can improve the computational efficiency of the system and be very suitable for processing large-scale seismic data. |
