Definitely sounds reasonable. > I was thinking a static MessageTag::invalid_tag = > std::numeric_limits<int>::min() or something like that, Something we can libmesh_assert() against? Yeah, that sounds good. I'd prefer for the default constructor to give something valid, but we can't get a unique valid tag without a Communicator argument... > but wasn't sure where to initialize it with this being header-only > now. I cheated and put Communicator_World (and now CommWorld) in libmesh.C, but there's no reason other than my laziness not to just create a parallel.C for those. --- Roy ------------------------------------------------------------------------------ LogMeIn Central: Instant, anywhere, Remote PC access and management.
