With Jeff's latest changes to how we set up the cq_size I am now seeing
error messages saying that my machine's memlocked limits are too low. I
am concerned that it might be something else because my max'd locked
memory is unlimited on my machine.
So if I do a run of -np 2 across two separate node than the use of the
max_cqe of my ib device (4194303) is ok. Once I go beyond 1 process on
the node I start getting the memlocked limits message. So how much
memory does a cqe take? Is it 1k by any chance? I ask this because the
machine I am running on has 4GB of memory and so I am wondering if I
just don't have enough backing memory and if that is so I am wondering
how commone of a case this may be?
