openmpi/opal/mca/base/mca_base_param.c
Josh Hursey 0404444dbe * Added 2 new MCA parameters 
- mca_base_param_file_prefix
     (Default: NULL)
     This is the fullname of the "-am" mpirun option. Used to specify a ':'
     separated list of AMCA parameter set files.
  - mca_base_param_file_path
     (Default: $SYSCONFDIR/amca-param-sets/:$CWD)
     The path to search for AMCA files with relative paths. A warning will be
     printed if the AMCA file cannot be found.

* Added a new function "mca_base_param_recache_files" the re-reads the file
configurations. This is used internally to help bootstrap the MCA system.

* Added a new orterun/mpirun command line option '-am' that aliases for the
mca_base_param_file_prefix MCA parameter

* Exposed the opal_path_access function as it is generally useful in other
places in the code.

* New function "opal_cmd_line_make_opt_mca" which will allow you to append a
new command line option with MCA parameter identifiers to set at the same
time. Previously this could only be done at command line declaration time.

* Added a new directory under the $pkgdatadir named "amca-param-sets" where all
the 'shipped with' Open MPI AMCA parameter sets are placed. This is the first
place to search for AMCA sets with relative paths.

* An example.conf AMCA parameter set file is located in
contrib/amca-param-sets/.

* Jeff Squyres contributed an OpenIB AMCA set for benchmarking.

Note: You will need to autogen with this commit as it adds a configure param.
  Sorry :(
