<p>Cactus known-architectures files <code>lib/make/known-architectures/linux</code> and <code>lib/make/known-architectures/darwin</code> differ in whether they set defaults for <code>XXX_OPENMP_FLAGS</code>. Namely the Linux one contains: </p>

</pre></div>
<p>while the darwin (macOS) one does not set any defaults. Other architectures (aix) set a them as well while yet others (all others) do not.</p>
<p>Ideally the defaults should be the same for all architectures (and nowadays probably <code>-fopenmp</code>). The value of <code>OPENMP</code> itself (ie if OpenMP is used) is not set by any architecture file.</p>
