I was thinking of doing the former way. But that requires sharing of CQ/QP
etc.
So now going ahead with plan where the CM setups up some minimal set of QPs
through which the clients can send their connection requests and the clients
themselves
handle creation of IB objects like QP, CQ . However there are other cases
where it is
benefitial to share the QPs across multiple processes. So creating IB
objects in shared
memory is useful.

Thanks
