What about RoCE? Is this something that is commonly used (I would guess
no since I have not found much)? Are there other protocols that are
worth considering (like "gamma" which doesn't seem to be developed anymore)?
My impression is that with RoCE you have to use specialized hardware
(unlike gamma - where one could use standard hardware, and still get a
noticeable improvement in latency)?
Thoughts?

Thanks Peter for the high level overview! A few followup questions. What
if I am using a non-Infiniband cluster, i.e something with 10gigE. Or
even slower like at my home I have a raspbery pi cluster with 100 Mbps
ethernet. Is ofed/psm/verbs all irrelevant?
Pretty much, yes, unless you've got fancy switches that can do RoCE.
