Subject: Re: [OMPI users] Displaying Selected MCA Modules
From: Joshua Bernstein (jbernstein_at_[hidden])

Well to answer my own question,

        If I use the -display-map option, I get printed out a nice bit of
information that includes a list of the modules in use during the run as
shown below:

                 Argv[0]: ./cpi
                 Env[0]: OMPI_MCA_pls=proxy
                 Env[1]: OMPI_MCA_rmaps_base_display_map=1
                 Env[3]: OMPI_MCA_rds=proxy
                 Env[4]: OMPI_MCA_ras=proxy
                 Env[5]: OMPI_MCA_rmaps=proxy
                 Env[6]: OMPI_MCA_rmgr=proxy
                 Working dir: /home/ats (user: 0)
