14 Establishes a reliable RDMA connection between two nodes using the
15 librdmacm, optionally performs RDMA transfers between the nodes,
26 On the server, specifies the network address to bind the connection to.
27 To bind to any address with IPv6 use -a ::0 .
28 On the client, specifies the server address to connect to.
31 The address to bind to as the source IP address to use. This is useful
32 if you have multiple addresses on the same network or complex routing.
35 Port number for listening server.
44 Display debug information.
47 The number of messages to transfer over each connection. (default infinite)
50 The size of each message transferred, in bytes. (default 100)
53 Run the server in persistent mode. This allows multiple rping clients
54 to connect to a single server instance. The server will run until killed.
56 Because this test maps RDMA resources to userspace, users must ensure
57 that they have available system resources and permissions. See the
58 libibverbs README file for additional details.
