Subject: Re: [OMPI users] openib segfaults with Torque
From: Nathan Hjelm (hjelmn_at_[hidden])

Well, thats interesting. The output shows that ibv_create_cq is
failing. Strange since an identical call had just succeeded (udcm
creates two completion queues). Some questions that might indicate where
the failure might be:

Does this fail on any other node in your system?

How long has the node been up?
