       ibv_uc_pingpong - simple InfiniBand UC transport test

SYNOPSIS

       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]

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)

       -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)

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.
