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, implicit dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.
- implicit dealiased convolutions
- hybrid OpenMP/MPI FFT
- adaptive distributed matrix transpose

Great library, makes the use of fftw much easier...
