FFTW ("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 arbitrarily large input size. FFTW also efficiently handles multiple, strided transforms.
FFTW is installed on LC's On LC's TOSS 3 Linux machines, FFTW is installed in /usr/tce/packages/fftw/*.
Intel's threaded Math Kernel Library (MKL) is a set of math libraries containing optimized BLAS, LAPACK, ScaLAPACK, FFT and other routines in the LC Linux environment. MKL is available only on LC machines with x86-based chips. Various versions of MKL are available in /usr/local/tools/mkl-<version> on CHAOS 5 systems and in /usr/tce/packages/mkl/mkl-<version> on TOSS 3 systems, where <version> is a specific version.
