%X The computation of traveling time of Pre-Stack Time Migration(PSTM) is the most time-consuming part of whole procedure.In this paper,we present a novel parallel algorithm to low the time of traveling-time computation.By using static interpolation with step of 8 points instead of dynamic step length,the new designed algorithm performs more accuracy and performance.Experimental results show that the speed-up number reaches 22.76 times.The statistical relative error demonstrates the better accuracy comparing w...
