ibv_uc_pingpong - simple InfiniBand UC transport test


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

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


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


-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)
-l, --sl=SL
use SL as the service level value of the QP (default 0)
-e, --events
sleep while waiting for work completion events (default is to poll for completions)


ibv_rc_pingpong(1), ibv_ud_pingpong(1), ibv_srq_pingpong(1)
