Install FFTW3 with MPI on Linux

Install FFTW3 With MPI

FFTW3 is a library designed to compute discrete Fourier transforms. As described

in the the official FFTW site, there are various versions available, with different

features and different levels of maturity. In this tutorial I deal with the

installation of version 3, including the experimental MPI version. However the

installation instructions seems to be valid (although not tested) also for the more

popular version 2.

General Remarks

As usual we would like to install the libraries in the user space, so we will create

a couple of directories for that purpose:

mkdir $HOME/usr

mkdir $HOME/soft

To install FFTW3, download the package from the FFTW3 download page and

decompress it:
