    MLFMA memory reduction techniques for solving large-scale problems
    (IEEE, 2014) Hidayetoğlu, Mert; Gürel, Levent
    We 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.

    Reducing MLFMA memory with out-of-core implementation and data-structure parallelization
    (IEEE, 2013) Hidayetoğlu, Mert; Karaosmanoğlu, Barışcan; Gürel, Levent
    We present two memory-reduction methods for the parallel multilevel fast multipole algorithm (MLFMA). The first method implements out-of-core techniques and the second method parallelizes the pre-processing data structures. Together, these methods decrease parallel MLFMA memory bottlenecks, and hence fast and accurate solutions can be achieved for largescale electromagnetics problems.
