Solution to the eikonal equation is used in seismic problems to determine first arrival travel times of seismic waves. In this paper we present a new parallel algorithm of the eikonal equation solution based on the Fast Sweeping Method (FSM). The algorithm achieves higher efficiency compared to existing parallel implementations of FSM due to optimization of CPU cache use.
