I'm confused by the WDC wiki page, specifically the part about the new ORTE_NOTIFIER_DEFINE_EVENT macro. Are you saying that I (as the developer) have to provide this macro with a unique notifier id? So that would mean that ORTE/OMPI would have to maintain a global notifier id counter to ensure it is unique?
If so, that seems really cumbersome. Could you please clarify?
