FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. In 2D and 3D, hybrid dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.

Features

  • implicit dealiased convolutions
  • hybrid dealiased convolutions
  • OpenMP/MPI FFT
  • adaptive distributed matrix transpose
