Previous Issues:

• #11726 -N bind ppr:X:node, map by package (socket), or core
  • Should OMPI binding defaults be a "reliable"?
    • Users shouldn't have to depend on this.
  • Just note that the default changed between v4.0 and v5.0
  • Consensus is that it's okay and that we should document this.
