Roland: I did exactly what you said with two cards on a node, however, if I use the two physical channels for Message striping, 99% of the test passed, but for some condition, I got IBV_WC_RETRY_EXC_ERR, or the code Just hangs there with no sending completion(ibv_poll_cq returns 0). Do you think this is a firware issue, Or the driver issue ?
