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

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.
