Hello, check orte/mca/plm and orte/mca/ras PLM - process lifecycle manager RAS - resource allocation subsystem. In RAS mpirun detects under which RM it works and gets the allocation. in PLM spawn of remote processes is done. mpirun spawns orted daemons on the slave nodes and all the rest is done without RM intervention (IMHO). > > Thank you. > > _______________________________________________ > devel mailing list > de...@open-mpi.org > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/devel > Link to this post: > http://www.open-mpi.org/community/lists/devel/2015/03/17157.php > -- С Уважением, Поляков Артем Юрьевич Best regards, Artem Y.
