Usage Information:
FFTW is installed on TG-NCSA in the directory /usr/projects/ncsamath/fftw

version 2.1.5 is installed in fftw-2.1.5 directory
mpichgm-intel built library in mpichgm-intel directory

version 3.1.1 is installed in fftw-3.0.1
intel90 built library in intel90 directory

Version 3.1.1

Version 3.1.1, which currently does not have MPI enabled FFT routines, was built with Intel 9.0 compiler and with the GNU compiler.

To use FFTW 3.0:

Intel compiler: soft add +fftw-3-intel90

GNU compiler: soft add +fftw-3-gnu

Compiling and Linking:
serial ifort -I $FFTW_HOME/include -o testf testf.f -L$ FFTW_HOME/lib -lfftw3
threaded ifort -I $FFTW_HOME/include -o testf testf.f -L $FFTW_HOME/lib -lfftw3_threads -lfftw3

For single precision, use -lffw3f.

NOTE: Version 8.0 of Intel's Math Kernel Library (MKL) provides a wrapper to FFTW3 so that FFTW users can also try using MKL's DFTI routines by recompiling and linking. See the software repository entry for MKL for more information.
