Usage of FFTW on JUWELS

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


FFTW Version 3.3.8 is available on JUWELS with Intel compiler and ParaStationMPI and IntelMPI, with GCC/7.3.0 and ParaStationMPI and with GCC/5.5.0 and MVAPICH2


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 [Intel IntelMPI] [GCC/7.3.0 ParaStationMPI] [GCC/5.5.0 MVAPICH2/2.3a-GDR]
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-3.3.8 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
