In fact there is a manual mode in hydra. Try this:
<div class=""><br class="">
</div>
<div class=""> mpiexec -n 2 -launcher=manual -host=A,B date</div>
<div class=""><br class="">
</div>
<div class="">It will print out the launch command lines and wait (very patiently). Then if you paste the proxy command line on your local host or any host on your network, it will continue. </div>
<div class=""><br class="">
</div>
<div class="">I guess that is all the pipelines that you can use to create your own wrapper scripts to work for custom environment. </div>

Having a manual mode of launching proxies sounds very interesting. I don’t think currently hydra supports it though.
<div class=""><br class="">
</div>
<div class="">The manually launched proxies need establish communication back to mpiexec.hydra — I suspect the mechanism already exist. I guess the next question is how to reliably detect launch failures other than having mpiexec.hydra hanging forever — maybe
that is a valid option. <br class="">

<div dir="ltr" class="">Hi,
<div class=""><br class="">
</div>
<div class="">I'm trying integrate MPICH with network submission tool called RTDA(RunTime Design Automation -
<a href="http://www.rtda.com/" class="">www.rtda.com</a>), I use the mpich-3.2.1a but looks like that mpich doesn't detect the resource manager and launcher, mpich cannot distribute jobs as expected.</div>
<div class=""><br class="">
</div>
<div class="">Does mpich support interact with RTDA resource manager and launcher? </div>
<div class=""><br class="">
</div>
<div class="">Since the hydra process manager did tight integration with SGE, LSF, SLURM, PBS, etc. I was thinking for platform it doesn't support - if there is way to submit jobs with loose integration? </div>
<div class="">( loose integration means that we do the job submission self and run hydra_pmi_proxy on each allocated node manually, instead of mpich finished everything under the hood.</div>
<div class="">)</div>
<div class=""><br class="">
</div>
<div class="">Thank you very much,</div>
