Greetings Josh.
No, we don't have an easy way to show which plugins were loaded and
may/will be used during the run. The modules you found below in --
display-map are only a few of the plugins (all dealing with the run-
time environment, and only used on the back-end nodes, so it may not
be what you're looking for -- e.g., it doesn't show the plugins used
by mpirun).
What do you need to know?

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:
---SNIP---
Argv[0]: ./cpi
Env[0]: OMPI_MCA_pls=proxy
Env[1]: OMPI_MCA_rmaps_base_display_map=1
Env[2]:
OMPI_MCA_orte_precondition_transports
=ad81e32181314110-4aea4dd5040c2593
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)
---END SNIP--

Hi There,
I'm attempting to debug some configuration issue with the recent
version of OMPI, version 1.2.6. I'm able to build all of the MCA
modules, and I've figured out how to display the list of AVAILABLE
modules using ompi_info, but is there a way to display the list of
modules that was selected at runtime? I've tried the -v option to
mpirun, and read through the FAQs, but I can't seem to figure out
how to have OMPI display the selected MCAs when a job starts. Any
help or guidance would be appreciated.
-Josh
