I inadvertently noted that btl/uct has the highest exclusivity and
consider all procs are reachable.
As a consequence :
- btl/uct is used in altogether with btl/vader for intra-node
- btl/uct is used altogether with btl/self for self communications
This behaviour is likely suboptimal and could/should be changed.
Can you please provide directions (uct vs self, and uct vs vader) ?
Once the policy is decided, the changes are trivial and I will be happy
to issue a PR.
