DESCRIPTION         top

       Run a simple ping-pong test over InfiniBand via the reliable
       connected (RC) transport.

OPTIONS         top

       -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=SIZE
              path MTU SIZE (default 1024)

       -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)

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

       -o, --odp
              use on demand paging

       -P, --prefetch=
              prefetch an ODP MR

       -t, --ts
              get CQE with timestamp

       -c, --chk
              validate received buffer

       -j, --dm
              use device memory

       -N, --new_send
              use new post send WR API

BUGS         top

       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.
