both, I was thinking of listing what I think are multi-rail requirements but wanted to understand what the current state of things are

Are you asking what *does* it do, or what *should* a BTL do?

Gleb,

Another question. What about the case of one node with 2 ports and one node with one port. Does the open ib btl allow the side with 2 ports to
establish two  endpoints to the single remote port?

How would the openib btl handle the following scenario:
Two nodes, each with two ports, all ports are on the same subnet and switch.

Would striping occur over 4 connections or 2?


Only two connections will be created.



If 2 is it equal distribution or are both local ports connected to the
same remote port?



Equal distribution.
