[gmx-users] replacement for FFTW

[Nathan Moore]

Maybe porting was the wrong word.  I'm cross compiling (on one PowerPC
architecture for execution on a different PowerPC architecture) and would
prefer to use the IBM essl fourier transform over the fftw routine.

Thus far GROMACS has not worked right out of the box for me.

thanks for your reply!
