The following example shows how to run a diagnostic between a local node client and a remote node server with the ib_write_bw command. First configure the remote node server with the command: ib_write_bw -d ocrdma0 -b -F -D 30 –cpu_util The important parameters have the following meaning:-d ocrdma0 Uses the InfiniBand device ocrdma0.
9/28/2010 · I did benchmark the achievable transfer rate using you example (transfering chunks of 8 MB) and it seems that the bandwidth is arond 650 MBps, while ib_ write _bw claims that bandwidth should be around 1500 MBps. Do you have.
