Which FFTW3 build to use on Discoverer

FFTW3 is an important library package that provides large number of HPC applications with a collection of external subroutines for computing the discrete Fourier transform (DFT) in one or more dimensions. In HPC environment it is a common case to have several different builds of FFTW3 available to support the variety of installed MPI libraries, threads libraries, and common models for application code building, linking, and executing. But in spite how many such builds are presented locally, the most compatible…
