Description
Suppose I have 3 machines and each machine has 8 network NICs.
Does Gloo for collective communication use all the network NICs in one process(use IB not tcp)?
(For example, NCCL will detect all the network NICs in the current environment during initialization, and will use all the network NICs when the bandwidth permits)
@sofong5 @osalpekar @pietern Any advices will help me.

Research direction
This is a capability question rather than a scoped code task, and the issue names no file, test, or entry point. Start by tracing Gloo's collective communication and IB versus TCP transport initialization, then determine whether multiple NICs are discovered and used. Done means a documented, reproducible answer or a clearly scoped implementation plan.
