fftwf_plan gmx_fft_fftw3::plan[2][2][2]

FFTW plans.

Three alternatives (unaligned/aligned, out-of-place/in-place, forward/backward) results in 8 different FFTW plans. Keep track of them with 3 array indices: first index: 0=unaligned, 1=aligned second index: 0=out-of-place, 1=in-place third index: 0=backward, 1=forward
