If specified, a comma-delimited list of TCP interfaces. Interfaces will be assigned, one to each MPI process, in a round-robin fashion on each server. For example, if the list is "eth0,eth1" and four MPI processes are run on a single server, then local ranks 0 and 2 will use eth0 and local ranks 1 and 3 will use eth1. This feature is only useful for environments with virtual ethernet interfaces on the same network. For example, if eth0 and eth1 are virtual interfaces to the same NIC on the same subnet, and if the NIC provides different hardware resources to eth0 and eth1 (not just different kernel resources), some HOL blocking and congestion issues can be eased in a modest fashion.
