NAME

       ibv_rc_pingpong - simple InfiniBand RC transport test

SYNOPSIS

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

       ibv_rc_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.
