Ah; OK. Sort of like what FFTW does for fft's, but probably with its own
twist. So if the "volk_config" file exists, VOLK reads it and uses it to
determine which kernel to use for a given VOLK algorithm instantiation. [Is
there a proper VOLK-like name for a "VOLK algorithm instantiation"?] If this
file does not exist, how does VOLK pick the kernel? Is this info somewhere in
a Wiki? I haven't looked, so forgive me if I'm asking FAQ's. - MLD
