Usage Information:

FFTW is installed in /usr/apps/math/fftw on the Abe cluster.

Version 2.1.5

Version 2.1.5 is compiled with both the Intel compiler, GNU gcc for MPI implementations MVAPICH2, OpenMPI and MPICH-VMI.
To use FFTW latest 2.X.X:

Intel and MVAPICH2: soft +fftw-2-mvapich-intel

GNU and MVAPICH2: soft +fftw-2-mvapich-gcc

Replace mvapich with openmpi or mpichvmi to use the other MPI implementations.

Compiling and Linking
Include files: -I $FFTW_HOME/include

Libraries: -L $FFTW_HOME/lib

FFTW was compiled with the prefix labeled precision libraries. 'd' is double and 's' is single.

Complex Transofrms

serial ifort -I $FFTW_HOME/include -o foo foo.f -L $FFTW_HOME/lib -ldfftw
threaded ifort -I $FFTW_HOME/include -o foo foo.f -L $FFTW_HOME/lib -ldfftw_threads -ldfftw -lpthreads
MVAPICH2 mpicc -I $FFTW_HOME/include -o foo foo.f -L $FFTW_HOME/lib -ldfftw_mpi -ldfftw

Real Transforms
(use the same include and library flags as above)
-ldrfftw -ldfftw
-ldrfftw_threads -ldfftw_threads -ldrfftw -ldfftw
-ldrfftw_mpi -ldfftw_mpi -ldrfftw -lfftw

Please see the User Guide for more information in using FFTW in your application.

NOTE: New versions 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.
