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 Linux.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.
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 kernel) do their own magic there. I think Mellanox should address this question.
