Struct TempLat::KokkosFFTPlanHolder::Plans

ClassList > TempLat > KokkosFFTPlanHolder > Plans

What's the intention here? Well, KokkosFFT does not support multi-dimensional FFTs directly, but only 1D, 2D and 3D FFTs. So for higher dimensions, we need to chain multiple FFTs together. This struct holds the plans for these FFTs, and provides methods to execute them in sequence. More...

void execute_r2c (const auto & src, const auto & dest)

Detailed Description

However.

We currently do not use this, as KokkosFFT does not support in-place transpositions. Therefore, we just fill a 1D, 2D or 3D plan and call that. I'm leaving this here for future reference, in case KokkosFFT adds in-place transposition or I (or someone else) implement it themselves.
