title = "Efficient parallelization of MLFMA for 3D electromagnetic scattering problems on sunway many-core processor SW26010",
abstract = "A many-core implementation of the multilevel fast multipole algorithm (MLFMA) based on the Athread parallel programming model for computing electromagnetic scattering by a 3-D object on the homegrown many-core SW26010 CPU of China is presented. In the proposed many-core implementation of MLFMA, the data access efficiency is improved by using data structures based on the Structure-of-Array (SoA). The adaptive workload distribution strategies are adopted on different MLFMA tree levels to ensure full utilization of computing capability and the scratchpad memory (SPM). A double-buffering scheme is specially designed to make communication overlapped computation. The resulting Athread-based many-core implementation of the MLFMA is capable for solving real-life problems with over four hundred thousand unknowns with a remarkable speed-up. Numerical results show that with the proposed parallel scheme, a total speed-up larger than 7 times can be achieved, compared with the CPU master-core.",
