It introduces a two incompatible versions of a popular Fourier Transform library into OpenSolaris. It requests a Minor release binding. The proposed man pages are in the case materials directory. The project team also intends to deliver the online html documentation with this project. The timer is set for 24 July 2008. Gary.. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Summary ======= 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 distributed-memory systems. FFTW is usually faster (and sometimes much faster) than all other freely-available Fourier transform programs found on the Net. For transforms whose size is a power of two, it compares favorably with the FFT codes in Sun's Performance Library and IBM's ESSL library, which are targeted at specific machines. Moreover, FFTW's performance is portable. Indeed, FFTW is unique in that it automatically adapts itself to your machine, your cache, the size of your memory, the number of registers, and all the other factors that normally make it impossible to optimize a program for more than one machine. An extensive comparison of FFTW's performance with that of other Fourier transform codes has been made. o FFTW computes the DFT of complex data, real data, even- or odd-symmetric real data (these symmetric transforms are usually known as the discrete cosine or sine transform, respectively), and the discrete Hartley transform (DHT) of real data. o The input data can have arbitrary length. FFTW employs O(n log n) algorithms for all lengths, including prime numbers. o FFTW supports arbitrary multi-dimensional data. o FFTW includes parallel (multi-threaded) transforms for shared-memory systems. The FFTW source base has two active branches, 2.x and 3.x. 3.x is where all new development will happen, but as 3.x breaks compatibility with 2.x, 2.x continues to be maintained, although it hasn't needed an update in several years. The current version is 3.1.5, but 3.2 is already available in alpha. FFTW does not include API documentation in man page format. Instead, API documentation is made available in info format. A PDF version of that document is attached, and an HTML version can be found online at [1]. The man page created for the port is also attached. FFTW will be integrated in the SFW consolidation as part of this proposal, and will be installed as SUNWfftw (2.x) and SUNWfftw3 (3.x). This project requests a minor release binding.
