In practice, FI_RANGE is difficult to use and harder to implement. Define an alternative method, FI_SYMMETRIC, instead, which allows an app to indicate that addresses on remote systems use the same transport addresses (port numbers), with an equal number of processes placed per node. This will simplify the implementation and the application usage of the interface, plus enable optimal storage of the data.

FI_SYMMETRIC would be paired with FI_RANGE. For example, an app could request a range of network addresses or hostnames (host100-host200), a starting transport address (port 5000), and the number of EP per node (32). The AV would insert all hosts 100-200 into the table with ports 5000-5031 for each host.
