"""FFTW (AMD Optimized version) is a comprehensive collection of

|
fast C routines for computing the Discrete Fourier Transform (DFT)
|
|
and various special cases thereof.
|
|
|
|
It is an open-source implementation of the Fast Fourier transform
|
|
algorithm. It can compute transforms of real and complex-values
|
|
arrays of arbitrary size and dimension.
|
|
AMD Optimized FFTW is the optimized FFTW implementation targeted
|
|
for AMD CPUs.
|
|
|
|
For single precision build, please use precision value as float.

|
Example : spack install amdfftw precision=float
