Fftw manual 2.1.5

Among the possible FFT libraries that can be linked to Qbox, the easiest library to install is FFTW (FFTW3 is available but Qbox uses only FFTW2). Simply download it from the FFTW download page and decompress it. FFTW is an older, now unsupported version, but still commonly used by codes as the API has changed in later versions. The versions compiled by the RCC support shared memory parallelism through OpenMP and distributed parallelism through MPI. This document was generated on 26 November using the texi2html translator version (properly hacked by athena@www.doorway.ru).

FFTW is an older, now unsupported version, but still commonly used by codes as the API has changed in later versions. The versions compiled by the RCC support shared memory parallelism through OpenMP and distributed parallelism through MPI. This manual documents version of FFTW, the Fastest Fourier Transform in the West. FFTW is a comprehensive collection of fast C routines for computing the discrete Fourier transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. FFTW also includes parallel transforms for both shared- and. FFTW For version , 26 November Introduction; Tutorial. Usage of MPI FFTW for Complex One-dimensional Transforms; MPI Tips.
