Abstract: High precision solution of 3D large-scale scattering problems is attainable most efficiently via multi-level fast multipole algorithm (MLFMA) accelerated solution of surface integral equations. Construction of MLFMA accelerated HO Locally corrected Nyström (LCN) discretization of CFIE presents various challenges as it requires all stages of the numerical scheme to maintain desired precision. Parallelization of the scheme for distributed memory multiprocessors introduces additional complexity to the method. In this work the outline of parallel implementation of HO solution of the CFIE via MLFMA accelerated LCN is given and accuracy of EFIE solution is studied. The study is done on the problem of radial dipole field scattering on perfectly conducting sphere modeled exactly via cube-to-sphere analytical mesh mapping.
