DESCRIPTION         top

       Run a simple ping-pong test over InfiniBand via the unreliable
       connected (UC) transport.

OPTIONS         top

       -p, --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.
