Webmpi4py-fft is a Python package for computing Fast Fourier Transforms (FFTs). Large arrays are distributed and communications are handled under the hood by MPI for Python (mpi4py). To distribute large arrays we are using a new and completely generic algorithm that allows for any index set of a multidimensional array to be distributed. WebOperating FFTW in multithreaded mode is supported. The core interface is provided by a unified class, pyfftw.FFTW . This core interface can be accessed directly, or through a series of helper functions, provided by the pyfftw.builders module. These helper functions provide an interface similar to numpy.fft for ease of use.
