Item Open Access An efficient parallel implementation of the multilevel fast multipole algorithm for rigorous solutions of large-scale scattering problems(IEEE, 2010) Ergül O.; Gürel, LeventWe present the solution of large-scale scattering problems discretized with hundreds of millions of unknowns. The multilevel fast multipole algorithm (MLFMA) is parallelized using the hierarchical partitioning strategy on distributed-memory architectures. Optimizations and load-balancing algorithms are extensively used to improve parallel MLFMA solutions. The resulting implementation is successfully employed on modest parallel computers to solve scattering problems involving metallic objects larger than 1000λ and discretized with more than 300 million unknowns. © 2010 IEEE.Item Open Access MLFMA memory reduction techniques for solving large-scale problems(IEEE, 2014) Hidayetoğlu, Mert; Gürel, LeventWe present two memory reduction methods for the parallel multilevel fast multipole algorithm. One of these methods uses data structures out of core, and the other parallelizes the data structures related to input geometry. With these methods, large-scale electromagnetic scattering problems can be solved on modest parallel computers. © 2014 IEEE.
