Abstract
The finite-difference time-domain (FDTD) is a numerical analysis technique used for solving computational electrodynamic problems. The nature of the FDTD method is that simulation of big and complicated electromagnetic field problems requires a vast amount of computer operational memory and runtime. Parallel-processing techniques have been broadly applied to FDTD to accelerate the simulations. The parallelism of the FDTD algorithm is based on a fact that the computational domain can be divided into parts (sub-domains), and each processor in a parallel system deals with one or several sub-domains. The FDTD algorithm belongs to data parallelism model and can be effectively implemented on shared memory system architecture. The parallel FDTD method was implemented using TPL library. The Task Parallel Library (TPL) is a library for .NET that makes easy to parallelize the program using the advantages of .NET Framework. The speedup metrics of parallel FDTD algorithm were calculated and compared with Amdahl’s estimated speedup.
