Abstract(in English) | This paper describes electromagnetical field simulation using the 3D-FDTD method for antenna designing on a CUDA-compatible GPU. We used the split Perfectly Matched Layer as absorbing boundary condition. As is well known, the 3D-FDTD method is a kind of stencil computation and is considered better at GPU implementation. In order to find the best blocking size for the target GPU architecture, we empirically explored a design space of blocking size. We also propose a kernel join method as one of efficient optimization methods, which improves the total performance about 12% at the cost of a small increase in memory usage. As a result of evaluation, our implementation of the 3D-FDTD method on a GeForce GTX295 platform achieves about 110 times performance improvement compared to a simple CPU implementation, which is estimated about 3.45 times faster than an ideally parallelized CPU implementation using multi-core and SIMD instructions. |
