The intercomm collectives are all basically defined as data movement from one group to the other (*and* vice versa), with the obvious exception of Barrier, which has no data movement -- just synchronization.

- collectives with intracomms are data movement in the *same* group
- collectives with intercomms are data movement to the *other* group
