Ursula,
The failure you are experience is likely to be due to the configuration of your infiniband kernel driver.
From what I see in your detailed report, the current value of
/sys/module/mlx4_core/parameters/log_mtts_per_seg
seems set to 0
After reading the two web pages listed at the bottom, I think that for RDMA on IB to work you need log_mtts_per_seg to be set to a non zero value, for example 1.
