Subject: Re: [OMPI users] deprecated MCA parameter
From: Ralph Castain (rhc_at_[hidden])

Guess I'm confused - what is the issue here? The param still exists:

                 MCA plm: parameter "plm_rsh_agent" (current value: <ssh : rsh>, data source: default value, synonyms:
                          pls_rsh_agent, orte_rsh_agent)
                          The command used to launch executables on remote nodes (typically either "ssh" or "rsh")

I am unaware of any plans to deprecate it. Is there a problem with it?
