Description
In this paper, we propose an implementation of a volumetric parallel three-dimensional fast Fourier transform (FFT) on massively parallel cluster of multi-core processors. Our proposed volumetric parallel three-dimensional FFT algorithm is based on the multicolumn FFT algorithm. We show that a two-dimensional distribution improves performance effectively by reducing the communication time for larger numbers of MPI processes. We successfully achieved performance of over 401 GFlops on the T2K-Tsukuba system with 4,096 cores for 256^3-point FFT.
