OPTIONS         top

       -p, --port=PORT
              use TCP port PORT for initial synchronization (default

              use IB device DEVICE (default first device found)

       -i, --ib-port=PORT

BUGS         top

       The network synchronization between client and server instances is
       weak, and does not prevent incompatible options from being used on
       the two instances.  The method used for retrieving work
       completions is not strictly correct, and race conditions may cause
       failures on some systems.
