Parallel Three-Dimensional Fast Fourier
Transforms, dubbed P3DFFT, is a library for
computing 3D FFTs using 2D (pencil) decomposition.
It is written using Fortran with MPI, and is tuned
to work on multiple single-CPU systems (up to
32768 of them). It is built to leverage
high-performance serial 1D FFT libraries, such as
FFTW or ESSL.
