[lammps-users] parallel FFT

I’m starting to use fftw, and I found its parallel library. I wanted to know if I can guide the use of your library .

I use linux with MPICH2, I’m reading your makefile.linux and I’m changing the ways of the libraries .

but dont understand how to use . appreciated if you can help me .

LAMMPS uses FFTW (or other FFT libs) for
their 1d on-processor FFTs. LAMMPS does
the parallel part itself.

lammps does its own parallelization of the FFT. no parallel FFT library needed.
