fftw
Fast C library for the Discrete Fourier Transform
The Fastest Fourier Transform in the West 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. It is becoming the FFT library of choice for most applications. Benchmarks, performed on a variety of platforms, show that FFTW's performance is typically superior to that of other publicly available FFT software.

Use flags of 3.3.11
- doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- fortran Add support for fortran
- mpi Add MPI (Message Passing Interface) layer to the apps that support it
- openmp Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- threads Add threads support for various packages. Usually pthreads
- zbus Adds support for ZBus cycle-counter of mips
