NAME
ibv_srq_pingpong - simple InfiniBand shared receive queue test
SYNOPSIS
ibv_srq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-q num
QPs] [-r rx depth] [-n iters] [-l sl] [-e] HOSTNAME
ibv_srq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-q num
QPs] [-r rx depth] [-n iters] [-l sl] [-e]
DESCRIPTION
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).
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)
-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)
-l, --sl=SL
use SL as the service level value of the QPs (default 0)
-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.
