[Boost-users] [MPI] lifetime of data sent through communicator::isend()

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? Does setting BOOST_MPI_HOMOGENEOUS have any influence on this? Best regards, Riccardo
