http://www.open-mpi.org/community/lists/devel/2014/05/14822.php Revamp the ORTE global data structures to reduce memory footprint and add new features. Add ability to control/set cpu frequency, though this can only be done if the sys admin has setup the system to support it (or you run as root). This commit was SVN r31916.
