Keywords:
Electromagnetic scattering, fast multipole method (FMM), FPGA, GPU, high performance reconfigurable computer (HPRC), iterative solvers, method of momentsAbstract
The fast multipole method (FMM) for large-scale electromagnetic scattering problems is implemented on high performance computing (HPC) platforms and its performance is investigated in terms of accuracy, speedup, and scalability. The HPC platforms include a 13-node graphical processing unit (GPU) cluster, and a field programmable gate array (FPGA)-based high performance reconfigurable computer (HPRC). The details of the implementations and the performance achievements are shown and analyzed. We demonstrate a scalable parallelization while maintaining a good degree of accuracy.
