Hello,
I'm using mpi::communicator::isend where the payload data comes from a pointer (e.g., "req = comm_.isend(dest, tag. *data)"). When am I free to "delete" the pointer? Immediately after isend() returns? Or should I wait until the request is completed?
yes, you have to wait before you can free your memory. See http://www.mpi-forum.org/docs/mpi22-report/node57.htm and the following pages.
Does setting BOOST_MPI_HOMOGENEOUS have any influence on this?
It should not have any influence on this. Heiko -- -- Wer das Leben nicht schätzt, der verdient es nicht. (Leonardo da Vinci) -- Number Crunch Blog @ http://numbercrunch.de -- Cluster Computing @ http://www.clustercomputing.de -- Heiko Bauke @ http://www.mpi-hd.mpg.de/personalhomes/bauke
