Hi All,<br>
<br>
We (Jim and I) have made some progress on the communicator
assertions effort! The new ticket 476 (see below) has a new version
of the MPI Standard with changes designed to<br>
<ul>
<li>oblige the user to comply with any INFO keys applied to any
MPI object or operation - turning all hints into
assertions/promises<br>
</li>
<li>prevent the propagation of INFO keys during MPI_COMM_DUP and
MPI_COMM_IDUP operations - to protect legacy libraries from have
their allowed behaviour being restricted by non-library code</li>
</ul>
We intend to read this at the face-to-face meeting in June.<br>
<br>
Please review the marked-up changes in the document. Any comments,
suggestions, word-smithing can be sent by email. Jim has offered to
run the teleconference meeting on Monday 11th May at 11am CDT so
that the WG can review and approve this text before the formal
reading notice deadline.<br>
<p>Cheers,<br>
</p>
Dan.<br>
