Don't understand what the air gapped reference means.
I don't know how to do it otherwise.

One other thing I hope to talk is some fabric query functionalities for
normal user,
not only just for root. This is at IB verbs level, not rdma_cm level.

Thanks. When can we have the SA features, very soon, long time, or never ?

I'm unaware of any current plans to implement these but my knowledge is
far from complete...

I can reproduce this. Lemme dig into it...

Guys,
I think this is the same iWARP issue that has been biting me for a
while: The client must send the first RDMA message. The dtest app is a
peer-2-peer (p2p) application where both sides send immediately after
setting up the connection. So dtest doesn't adhere to the iWARP

The problem is, from MPI side, (and by default), we don't know which port is
