SYNOPSIS

       ibv_xsrq_pingpong  [-p  port] [-d device] [-i ib port] [-s size] [-m mtu] [-c clients] [-n num_tests] [-l
       sl] [-e] [-g gid index] HOSTNAME

       ibv_xsrq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-m mtu] [-c clients] [-n  num_tests]  [-l
       sl] [-e] [-g gid index]

DESCRIPTION

       Run  a simple ping-pong test over InfiniBand via the extended reliable connected (XRC) transport service,
       using a 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)

       -m, --mtu=MTU
              use path mtu of size MTU (default 2048)

       -c, --clients=CLIENTS
              number of clients CLIENTS (on server only, default 1)

       -n, --num-tests=NUM_TESTS
              perform NUM_TESTS tests per client (default 5)

       -l, --sl=SL
              use SL as the service level value (default 0)

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

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

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.
