Run a simple ping-pong test over InfiniBand via the extended reliable connected (XRC) transport service, using a shared receive queue (SRQ).
-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 4096) -m, --mtu=MTU use path mtu of size MTU (default 2048) -c, --clients=CLIENTS number of clients CLIENTS (on server only, default 1) -n, --num-tests=NUM_TESTS perform NUM_TESTS tests per client (default 5) -l, --sl=SL use SL as the service level value (default 0) -e, --events sleep while waiting for work completion events (default is to poll for completions) -g, --gid-idx=GIDINDEX local port GIDINDEX
