Ralph, Reuti, There are no typos, except in my post itself where I clipped out a few arguments.
I just repeated the exercise this morning, exactly like this: <path>/bin/mpirun --machinefile mpihosts.dat -np 16 -mca orte_rsh_agent /usr/bin/rsh -x MPI_ENVIRONMENT=1 ./test_setup It prompts for a password. Then I hit the "up" arrow key to bring the command back, and I type over "orte" and replace with "plm": <path>/bin/mpirun --machinefile mpihosts.dat -np 16 -mca plm_rsh_agent /usr/bin/rsh -x MPI_ENVIRONMENT=1 ./test_setup This time it does not prompt for a password. I can reverse the order, it doesn't change the behavior: the "orte" one prompts for a password but the "plm" one doesn't. They must not be wholly identical, somehow. This is OpenMPI 1.4.3.

Not sure what the issue might be, but I would check for a typo - we don't check that mca params are spelled correctly, nor do we check for params that don't exist (e.g., because you spelled it wrong).

Did I miss some critical piece of information? Why do these options behave differently?
