<div>During the FT plenary session at the Jan. MPI Forum meeting
there were some concerns about fault tolerance semantics in the
I/O chapter. We did not have much time to fully discuss the
additional semantics during the meeting. To make sure that we
push towards a complete set of semantics useful for the I/O
community in the next draft I would like to have a teleconf to
discuss the I/O chapter of the FT proposal. Preferability in the
next week and a half (so we have time to fine tune things before
the next forum meeting).</div>
<div><br>
</div>
<div>Below is a link to a doodle poll to find a good time for a
teleconf. If you are interested in participating in this
discussion, please fill this poll out by 2 PM Eastern on Thurs.
Feb. 2 so we can set the date/time.</div>
