| Abstract(in English) | Using techniques of parallel computing, we study speeding-up of large-scale numerical simulations of optical fiber transmission based on Split-Step Fourier Method (SSFM). Since the process time of SSFM is mostly spent on fast Fourier Transform, faster execution of FFT is required. Thus, we developed an original FFT subprogram using MPI parallel API. An SSFM program using our FFT subprogram is compared with another SSFM program using an established parallel FFT, six-step FFT, in terms of their execution speed. The advantage of multiprocessing is expected for the number of data more than 2^<16> for eight processes and more than 2^<24> for four processes, respectively. Comparing our parallel FFT with six-step FFT, the latter will be more promising for fast execution when used with multiple processes. |
