The open/select of the PLM is done in orte/mca/ess/base/ess_base_std_orted.c. It only is done when the PLM MCA param is set directing a specific PLM be selected. The function orte_plm_base_orted_append_basic_args clears the params passed to the daemon of any PLM selection passed to the HNP. Each PLM then adds a PLM directive if-and-only-if backend PLM support is desired. At present, Torque, SLURM, and rsh all specify this support and direct that the backend orted open the "rsh" PLM. This commit was SVN r21488. The following SVN revision numbers were found above: r21480 --> open-mpi/ompi@ed585bce8a
