The two are synonyms for each other - they resolve to the identical variable, so there isn't anything different about them.
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).

I have a hello world program that runs without prompting for password with plm_rsh_agent but not with orte_rsh_agent, I mean it runs but only after prompting for a password:
<path>/bin/mpirun --machinefile mpihosts.dat -np 16 -mca plm
_rsh_agent /usr/bin/rsh ./test_setup
Hello from process 0
Hello from process &n bsp; 10
<path>bin/mpirun --machinefile mpihosts.dat -np 16 -mca orte
I didnít notice anything about this in the FAQ except that orte_rsh_agent is newer than plm_rsh_agent. Did I miss some critical piece of information? Why do these options behave differently?
