NAME
       ibv_ud_pingpong - simple InfiniBand UD transport test


SYNOPSIS
       ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx
       depth] [-n iters] [-l sl] [-e] [-g gid index] HOSTNAME

       ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx
       depth] [-n iters] [-l sl] [-e] [-g gid index]


DESCRIPTION
       Run a simple ping-pong test over InfiniBand via the unreliable datagram
       (UD) 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 2048)

       -r, --rx-depth=DEPTH
              post DEPTH receives at a time (default 500)

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

       -l, --sl=SL
              send messages with service level SL (default 0)

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

       -g, --gid-idx=GIDINDEX
              local port GIDINDEX

       -c, --chk
              validate received buffer

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.
