Hi Howard,
<div class=""><br class="">
</div>
<div class="">Thanks for the update. Sounds promising.</div>
<div class=""><br class="">
</div>
<div class="">I'm trying to fix the test3.zip example from:</div>
<div class=""><a href="https://github.com/open-mpi/ompi/issues/3458#issuecomment-322951227" class="">https://github.com/open-mpi/ompi/issues/3458#issuecomment-322951227</a><br class="">
<div class=""><br class="webkit-block-placeholder">
</div>
<div class="">If successful, this would extend the testing opportunities for the sandbox code to situations that involve more than one mpirun. The issue is definitely some sort of deadlock in PMIx but I’ve not figured it out completely yet.</div>

I’m cancelling the meeting today, unless anyone objects in the next 50 minutes.</div>

<div class="">I’ll be on a plane at 11 AM MDT today so will not be able to call in.</div>
<div class=""><br class="">
</div>
<div class="">I tried running the tests Dan had added/modified and observed</div>
<div class="">what he did, that one can’t allow more than one outstanding</div>
<div class="">accept/connect going on at a time or Open MPI’s ORTE gets confused.</div>
<div class="">I reduced this down to a simpler test which hangs with only 3 ranks</div>
<div class="">and am narrowing down what the issue is.</div>
<div class=""><br class="">
</div>
<div class="">I’ll be opening a PR with changes to chapter 8 of the standard and</div>
<div class="">replacement for MPI_Get_Set_Names later this week.</div>
