* 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 :( This commit was SVN r13867. 2007-03-01 16:39:20 +03:00			`#`
