NAME

       ibv_xsrq_pingpong - simple InfiniBand shared receive queue test

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.
