double* fft_data_struct::data_buf

int fft_data_struct::max_comm_size

Maximal size of the communication buffers.

fft_forw_plan fft_data_struct::plan[4]

Information about the three one dimensional FFTs and how the nodes have to communicate in between.

NOTE: FFT numbering starts with 1 for technical reasons (because we have 4 node grids, the index 0 is used for the real space charge assignment grid).
