ibv_srq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-q num QPs] [-r rx depth] [-n iters] [-e]

Run a simple ping-pong test over InfiniBand via the reliable connected (RC) transport, using multiple queue pairs (QPs) and a single 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)

-q, --num-qp=NUM use NUM queue pairs for test (default 16)

-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)
