By default, 551.ppalm uses the Temperton Algorithm to compute FFTs. By defining SPEC_HOST_FFTW3, the benchmark will instead use a user suppiled FFTW3 library. The arrays passed to this library will be the host copy.
Users must specify both -DSPEC_HOST_FFTW as well as the include path to the FFTW3 interface file, fftw3.f03. They must also add the FFTW3 libary to the libraries. For example:

Link using FFTW 3.3.10 library for Linux. Description from FFTW:
FFTW lib compiled with -xCORE-AVX512 -qopt-zmm-usage=high -Ofast -fp-model fast=2
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).
This result has been formatted using multiple flags files. The "sw environment" from each of them appears next.
Platform settings
One or more of the following settings may have been applied to the testbed. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.
LD_LIBRARY_PATH=<directories> (linker)
LD_LIBRARY_PATH controls the search order for both the compile-time and run-time linkers. Usually, it can be defaulted; but testers may sometimes choose to explicitly set it (as documented in the notes in the submission), in order to ensure that the correct versions of libraries are picked up.
STACKSIZE=<n> (Unix)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.
ulimit -s <n> (Unix)
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
