1. new functionality in the pls base to check for reusable daemons and launch upon them 2. an extension of the odls API to allow each odls component to build a notify message with the "correct" data in it for adding processes to the local daemon. This means that the odls now opens components on the HNP as well as on daemons - but that's the price of allowing so much flexibility. Only the default odls has this functionality enabled - the others just return NOT_IMPLEMENTED 3. addition of a new command line option "--reuse-daemons" to orterun. The default, for now, is to NOT reuse daemons. Once we have more time to test this capability, we may choose to reverse the default. For one thing, we probably want to investigate the tradeoffs in start time for comm_spawn'd processes that reuse daemons versus launch their own. On some systems, though, having another daemon show up can cause problems - so they may want to set the default as "reuse". This is ONLY enabled for rsh launch, at the moment. The code needing to be added to each launcher is about three lines long, so I'll be doing that as I get access to machines I can test it on. This commit was SVN r12608.
