Abstract

In this paper, we introduce a parallel version of the Fast Fourier Transform that was created using OpenMP in SPMD style. Our implementation is non-recursive and is based on the conventional Cooley-Tukey algorithm written in C. The aim of this work is show the potential benefit of writing our FFT algorithm in SPMD style which enabled an efficient use of multicore machines. Our experimental results are based on FFT code running on an AMD-Opteron TM8200 with four 2-core CPUs. The experimental results show that the performance of our new parallel code on an 8-core shared-memory machine is promising.
