WebPrevious implementations of these FMM algorithms led to the "street wisdom" that they are only practical for large, relatively square matrices, that they require considerable workspace, and that they are difficult to achieve thread-level parallelism. The thesis of this work dispels these notions by demonstrating significant benefits for small ...

Fast multipole method - Wikipedia

The fast marching method is a numerical method created by James Sethian for solving boundary value problems of the Eikonal equation: Typically, such a problem describes the evolution of a closed surface as a function of time with speed in the normal direction at a point on the propagating surface. The speed function is specified, and the time at which the contour crosses a point is obtained by solving the equation. … WebFMM algorithms. To present these ideas, we restrict our attention to the two-dimensional (2-D) layered media in this paper and organize the paper as follows: In Section 2, we summarize all necessary building blocks for the new algorithm and present the pseudocode and complexity analysis. Section 3 provides several Green’s func-tions examples. how to state problem statement in research
