[gmx-developers] Current status FFTW-3D

Hi Roland,

Wiki is pretty much up-to-date on the FFT stuff - I haven't had time  
for it myself (working on free energy perturbation right now) and my  
students seem to be busy :-)

There are some auxiliary projects involving more optimized FFT  
routines, but the primary project is mostly an exercise in book- 
keeping and efficient MPI communication. Essentially, the parallel  
version should use pre-existing 1D FFT calls and enable full 1D/2D/3D  
decomposition of the entire grid (currently we only do 1D).
