The HIE(Hybrid Implicit-Explicit)-FDTD method is very useful for the simulation of computational domain with thin cells. This paper describes the HIE-FDTD method with GPGPU(General Purpose computing on Graphic Processing Unit) for massively parallel electromagnetic field simulation. First, the properties of the HIE-FDTD method are explained. Next, 3D HIE-FDTD method with CUDA is implemented. Finally,...
The method Finite Difference Time Domain (FDTD) is widely used in electromagnetic simulations. Since this method is a data intensive and computation intensive problem, there are a lot of initiatives to improve the scalability and the performance of the FDTD. Specifically the use of GPU to accelerate the FDTD is in focus, which has a good cost-benefit, offering a speedup of hundreds of times if compared...
Simple models of major CPU-intensive MAGIC electromagnetic (EM) plasma code portions using the CUDA language run on the graphical processing unit (GPU) indicate 12x computing rate compared to the same calculations run on the CPU only. MAGIC is being modified for performance speedup of large-scale plasma-wave EM calculations using GPU processing. Results to-date from MAGIC with the particle update...
Recently, the use of graphics processing units as a means of achieving the hardware acceleration of the finite-difference time-domain (FDTD) technique has attracted significant interest in the computational electromagnetics community. However, the large memory requirements of the FDTD, compounded by the limited memory resources available in graphics processing units, compromise the efficiency of this...
