Subject: Re: [OMPI users] Accessing to the send buffer

As of MPI 2.2 there is no longer a restriction against read access to a
live send buffer. The wording was changed to now prohibit the user to
"modify". You can look the subsection of Communication Modes in chapter 3
but you will need to compare MPI 2.1 and 2.2 carefully to see the change.

The change was done by the MPI Forum under Ticket 45.
