No, I was looking for the earlier part of the log where mpiexec launches proxies. You may cut out the dump of environment variables if those are sensitive.</div>

That is strange. Try pass <code>-v</code> option (i.e. <code>mpiexec -v</code> ...) to obtain a console log when that happens.</div>

<div class="x_x_BodyFragment"><font size="2"><span style="font-size:11pt">
<div class="x_x_PlainText">Hi, I am using mpich on a hadoop cluster with yarn. It is not a smooth
<br>
integration but it is working.<br>
Flowing an old post, I am using the manual launcher and the option <br>
-disable-hostname-propagation <br>
(<a href="https://lists.mpich.org/mailman/htdig/devel/2016-July/000717.html" class="x_x_moz-txt-link-freetext x_moz-txt-link-freetext">https://lists.mpich.org/mailman/htdig/devel/2016-July/000717.html</a>)<br>
<br>
The command line to launch by binary is :<br>
<br>
mpiexec -launcher manual -disable-hostname-propagation -n 6 -f ./hosts <br>
/path/to/my/bin<br>
<br>
And the file hosts contains<br>
<br>
host1:2<br>
host2:2<br>
host3:2<br>
<br>
I expect to have 2 processes on each host but most of the time it <br>
launches 3 processes on host1, 1 on host2 and 2 on host3<br>
Any ideas?<br>
<br>
Bruno<br>
