FFTW

FFTW is a software module available on Comet.

Important!

Depending on your use case you may also need to look at FFTW.MPI.

FFTW overview

To access FFTW on Comet, run module load FFTW. This will load the default version of FFTW.

An overview of the module information is shown below (module -r spider ^FFTW$): 

FFTW:
    Description:
      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.

     Versions:
        FFTW/3.3.10-GCC-11.3.0
        FFTW/3.3.10-GCC-12.2.0
        FFTW/3.3.10-GCC-12.3.0
        FFTW/3.3.10-GCC-13.2.0
        FFTW/3.3.10-GCC-13.3.0
     Other possible modules matches:
        FFTW.MPI

  To find other possible module matches execute:

      $ module -r spider '.*FFTW.*'

  For detailed information about a specific "FFTW" package (including how to load the modules) use the module's full name.
  Note that names that have a trailing (E) are extensions provided by other modules.
  For example:

     $ module spider FFTW/3.3.10-GCC-13.3.0

If there are multiple versions of FFTW listed, then you can load a specific version as follows: 

$ module load FFTW/version_string

You can find the most up to date information whilst logged on to Comet by running module -r spider ^FFTW$.
