The Fastest Fourier Transform in the West (FFTW) is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size.
Many benchmarks show that FFTW's performance is typically superior to that of other publicly available FFT software. Moreover, FFTW's performance is portable: the program will perform well on most architectures without modification.
For more information see the FFTW home page.
FFTW library versions are available as modules. Only builds for the compute nodes are available. See the modules page for more information on modules. After loading an fftw module, the "info" utility can be used to get more information: "info fftw" for version 2.1.5 or "info fftw3" for fftw 3.*.
