Running ib_send_bw *shouldn't* have any affect on using ping. Did system2 crash, or is it still running? Can you see if anything running to the HCA works (e.g. try ibv_devinfo or sminfo)? >Am I doing something wrong? Or, is this a WinOF bug or a Windows 2008 bug? >(I'm CC'ing Sean & Stan for their advice on running ib-send-bw.) Can you also try running with ibv_send_bw and see if the results are the same? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
