3D EM simulations are nowadays widely used to design antenna systems, RF components and RF modules. The FDTD method shows significant advantages compared to frequency domain methods if the problems are getting complex and have to consider thousands of objects and complex multilayer circuits. This paper describes how the FDTD XPU technology (software accelerated computing on modern CPUs) can utilize...
Since Finite-Difference Time-Domain (FDTD) method was proposed by Yee in 1966, its hardware acceleration problem arouses much concern. In this paper, how to use GPU+COW parallel computing system to accelerate the FDTD method was introduced briefly. The acceleration scheme and the simulation results were presented, and then the feasibility and efficiency of the proposed scheme were proved.
The Parallel finite difference time domain (FDTD) algorithm is an important method to 1 enhance the speed in multiple data FDTD operation. The improvement of graphics processing unit (GPU) performance, especially the emergence of Computer Unit Device Architecture (CUDA), offers parallel FDTD method an efficient and simple solution. First of all, this paper explains parallel FDTD method and CUDA in...
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...
