<p>Comment (by Roland Haas):</p>
<p>Oh, right. So that won’t quite prevent cache line sharing. Unfortunately I cannot check alignment with a static assert since both types are allocated dynamically (<code>lc_thread_info_t</code> via a <code>new</code> the other as part of a <code>std::vector<lc_fine_thread_comm_t></code> (and I’d have no idea how that one would have interacted with the <code>CCTK_ATTRIBUTE_ALIGNED(128)</code>). </p>
<p>So I guess it would have to be using 2*128 or at least 2 times the cache line size if that one is know at compile time.</p>
