I mentioned on the call that for Mellanox devices (+OFA verbs) this resource is
really cheap. Do you run mellanox hca + OFA verbs ?
(I'll reply because I know Terry is offline for the rest of the day)
Yes, he does.
I asked because SUN used to have own verbs driver.
I noticed this on a Solaris machine, I am not sure I have the same set
up for Linux but I'll look and see if I can reproduce the same issue on

The heart of the question: is it incorrect to assume that we'll consume (num
CQE * CQE size) registered memory for each QP opened?
QP or CQ ? I think you don't want to assume anything there. Verbs (user and

I think Mellanox should address this question.
