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
