Comment (by Roland Haas):

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 \(`lc_thread_info_t` via a `new` the other as part of a `std::vector<lc_fine_thread_comm_t>` \(and I’d have no idea how that one would have interacted with the `CCTK_ATTRIBUTE_ALIGNED(128)`\).  
  
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.
