Detailed Description

template<typename FloatType, class FFTConfig>
struct P3MFFTHeffte< FloatType, FFTConfig >

heFFTe-backed implementation of the P3M FFT interface.

Thin adapter that exposes P3MFFT through the P3MFFTBackend virtual interface, so the solver can hold it interchangeably with other backends. This is the general backend, used for any rank count.
