Usage of FFTW on JURECA

FFTW has been installed on JURECA, it is also part of MKL.

FFTW version 3.3.8 is available compiled for ParaStation MPI and IntelMPI

Compilation and linking of a user-program name.c calling routines from fftw-3.3.8 double precision [OpenMP][MPI] is done by

module load intel-para
module load FFTW/3.3.8
gcc -o name -I$EBROOTFFTW/include name.c -L$EBROOTFFTW/lib [-lfftw3_omp] [-lfftw3_mpi] -lfftw3 -lm


Compilation and linking of a user-program name.c calling routines from fftw-3.3.4 single precision [OpenMP][MPI] is done by
module load intel-para
module load FFTW/3.3.8
gcc -o name -I$EBROOTFFTW/include name.c -L$EBROOTFFTW/lib [-lfftw3f_omp] [-lfftw3f_mpi] -lfftw3f -lm
