Abstract :
The OpenMP-CUDA Accelerated Moment Method (MoM) for the electromagnetic scattering by 3-D arbitrarily shaped homogeneous dielectric objects is presented. In the analysis, We use multi-GPUs controlled by OpenMP to accelerate the matrix filling and solving procedure. Specially, we adopt the well-behaved threshold-based incomplete LU preconditioner (ILUT) to improve the iteration convergence. Numerical results demonstrate that our implementation have a good precision and high speed-up ratio.
