[libfabric-users] Binding EP with memory region with flags?

[Lim, Jintack]

Thanks, Sayantan and Dave.

In fact, I re-compiled GASNet without binding mr to ep, and it just worked. 

Thanks,
Jintack

Agreed.  fi_mr_reg() registers the memory with the domain, not with an endpoint.

The man page for fi_endpoint(3) could probably use a tweak to avoid misleading users into thinking that binding MRs to EPs is necessary:

----8<----
       fi_ep_bind
              Associate  an  endpoint  with  an event queue, completion queue,
              counter, address vector, or memory region
----8<----
