FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).


To make this library available, run one the following:

module load FFTW/3.3.8-gompi-2019b
module load FFTW/3.3.8-gompi-2019a
module load FFTW/3.3.8-gompi-2018b
module load FFTW/3.3.8-gompic-2019b
module load FFTW/3.3.8-gompic-2019a
module load FFTW/3.3.8-intel-2019a
  • gompi versions are a subset of the foss toolchain and also load GCC and OpenMPI

  • gompic versions are a subset of the fosscuda toolchain and also load GCC, OpenMPI and CUDA.

  • intel versions use an intel toolchain and load the Intel compilers and Intel MPI.
