FFTW Installation with Intel, PGI, and GCC compilers
"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 arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
Download FFTW and extract the tarball in a sensible place (e.g., /usr/local/src/FFTW
. Note that you will probably want the 3.x and the 2.x series to satisfy a range of scientific applications. Installation is relatively simple, but is a little unusual. Each of the following will install the relevant version into /usr/local/FFTW/x.x.x
. Change to the appropriate directory and run the following configuration and make process.
module load intel
make clean
CC=icc F77=ifort ./configure --prefix=--prefix=/usr/local/$(basename $(pwd) | sed 's#-#/#')-intel --enable-mpi --enable-shared --enable-type-prefix --disable-float

Produce a module file the usual way (e.g., ln -s .base 3.1.3-gcc
). The .base module file looks like the following.
