NAME 

ibv_rc_pingpong - simple InfiniBand RC transport test

SYNOPSIS 

ibv_rc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-e] HOSTNAME

ibv_rc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-e]

DESCRIPTION 

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

OPTIONS 

-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)

-r, --rx-depth=DEPTH post DEPTH receives at a time (default 1000)

-n, --iters=ITERS perform ITERS message exchanges (default 1000)

-e, --events sleep while waiting for work completion events (default is to poll for completions)

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.
