Qnet supports transmission over multiple networks
and provides the following policies for specifying how Qnet
should select a network interface for transmission:
-
loadbalance (the default)
- Qnet is free to use all available network links, and
shares transmission equally among them.
-
preferred
- Qnet uses one specified link, ignoring all other
networks (unless the preferred one fails).
-
exclusive
- Qnet uses one — and only one — link,
ignoring all others, even if the exclusive link fails.
