In fact there is a manual mode in hydra. Try this: mpiexec -n 2 -launcher=manual -host=A,B date 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. I guess that is all the pipelines that you can use to create your own wrapper scripts to work for custom environment. — Hui On Oct 26, 2018, at 8:42 AM, Zhou, Hui <[email protected]<mailto:[email protected]>> wrote: Having a manual mode of launching proxies sounds very interesting. I don’t think currently hydra supports it though. 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.

Does mpich support interact with RTDA resource manager and launcher? 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? ( 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. ) Thank you very much, Shuwei _______________________________________________ discuss mailing list [email protected]<mailto:[email protected]> To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list [email protected]<mailto:[email protected]> To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
