Run a simple ping-pong test over InfiniBand via the unreliable datagram (UD) transport.
-p, --port=PORT use TCP port PORT for initial synchronization (default 18515) -d, --ib-dev=DEVICE use IB device DEVICE (default first device found) -i, --ib-port=PORT use IB port PORT (default port 1) -s, --size=SIZE ping-pong messages of size SIZE (default 2048) -r, --rx-depth=DEPTH post DEPTH receives at a time (default 500) -n, --iters=ITERS perform ITERS message exchanges (default 1000) -l, --sl=SL send messages with service level SL (default 0) -e, --events sleep while waiting for work completion events (default is to poll for completions) -g, --gid-idx=GIDINDEX local port GIDINDEX -c, --chk validate received buffer

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.
