Hello,
can anybody confirm if fftw-3.1.2 is compatible with gromacs 3.3.1 and
gromacs 4.0?
A colleague has recently indicated that I must use fftw 2.1.5 for
gromacs mpi. However, I have been using fftw-3.1.2 for quite a while
now. It compiles fine and my searching today turned up some other usage
here:

Possibly your colleague's memory is antiquated. FFTW 2.x had parallel
FFTs that might have been used by GROMACS at the time. This might
explain your colleague's association of MPI GROMACS and FFTW 2.1.5.
However certainly by 3.3.1, GROMACS is perfectly happy with any FFTW
version, since it handles the parallelism itself and so needs only
serial FFT routines.
