This is not correct - mpirun will not invoke an orted daemon on the master node. mpirun itself acts as the local daemon. > These environment variables passed to > slave nodes via mpirun options does not > take into effect before orted started. This is not entirely correct. It depends on the launcher. For rsh/ssh launchers, we do indeed set the environmental variables prior to executing the orted daemon.
