Discussion / Questions:

• Discussion (v3 only) PMIx Connect Server side
  • Currently client is passed back namespace and rank from connect call (MPI Sessions WG request)
  • On connect (and requesting a new namespace) a new namespace is assigned, so client will know the namespace and their rank in it.
    • Useful if we want to send a notification to this connected group, you can use the namespace as the handle for sending the notification.
  • Should the RM assign the new rank in the nspace (PRL server side API change needed for pmix_server_connect_fn_t callback), or let the PRL decide (no API change required?
    • Create a new API (since this only impacts v3)
    • PMIx_Group()
      • Create a new namespace and rank
      • Default connected (shared job info)
      • Attribute to not connect (useful for establishing a group for notification purposes only)
    • Ralph to make PMIx_Connect in 'master'/'v3.x' to 'v2.1' level
      • Define a couple new API's for grouping/ungrouping
