https://svn.boost.org/trac10/ticket/11074 <p> 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 or more complex types? </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/11074 Trac 1.4.3 anonymous Thu, 05 Mar 2015 16:19:32 GMT https://svn.boost.org/trac10/ticket/11074#comment:1 https://svn.boost.org/trac10/ticket/11074#comment:1 <ul> <li><strong>severity</strong> <span class="trac-field-old">Problem</span> → <span class="trac-field-new">Not Applicable</span> </li> </ul> <p> Sorry for the double post, I wasn't getting a reply from trac so tried again... </p> Ticket Matthias Troyer Thu, 05 Mar 2015 16:20:43 GMT https://svn.boost.org/trac10/ticket/11074#comment:2 https://svn.boost.org/trac10/ticket/11074#comment:2 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">duplicate</span> </li> </ul> Ticket
