So we need all the routing code for dealing with cross-job communications, lifelines, etc. The HNP will be directly connected to all daemons as they must callback at startup, and so we need to track those children correctly so we know when it is okay to terminate.
We still have to support direct launch, though, as this is the only component we can use in that scenario. So if the app doesn't have daemon URI info, then it must fall back to directly connecting to everything.
We recognize that this means other users of OPAL will need to "wrap" the opal_process_name_t if they desire to abstract it in some fashion. This is regrettable, and we are looking at possible alternatives that might mitigate that requirement. Meantime, however, we have to put the needs of the OMPI community first, and are taking this step to restore hetero and SPARC support.
VERY tentatively schedule this for 1.7.5 - only to be applied if we see no troubles AND the branch is ready in advance.
