11073,boost::mpi an order of magnitude slower than pure MPI for sending vector of doubles,ilja.j.honkonen@…,Matthias Troyer,As detailed in my email to boost users (h ttp://lists.boost.org/boost-users/2015/02/83807.php) it seems to take an order of magnitude longer to send a vector of doubles using boost::mpi than it takes using C bindings of MPI. I couldn't find anything in the documentation about optimizing transfers of standard types so I'd assume they are already optimized but that doesn't seem to be the case. Am I missing something or is there a serious performance issue in boost::mpi when sending (largeish) vectors of standard types?,Bugs,new,To Be Determined,mpi,Boost 1.57.0,Problem,,,
