DESCRIPTION
Run a simple ping-pong test over InfiniBand via the unreliable datagram (UD) transport.

- 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)

BUGS
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.
