NAME

       rping - RDMA CM connection and RDMA ping-pong test.

SYNOPSIS

       rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
                 [-C message_count] [-S message_size]
       rping -c [-v] [-V] [-d] -a address [-p port]
                 [-C message_count] [-S message_size]

DESCRIPTION

       Establishes  a  reliable  RDMA connection between two nodes using the librdmacm, optionally performs RDMA
       transfers between the nodes, then disconnects.

OPTIONS

       -s     Run as the server.

       -c     Run as the client.

       -a address
              On the server, specifies the network address to bind the connection to.  To bind  to  any  address
              with IPv6 use -a ::0 .  On the client, specifies the server address to connect to.

       -p     Port number for listening server.

       -v     Display ping data.

       -V     Validate ping data.

       -d     Display debug information.

       -C message_count
              The number of messages to transfer over each connection.  (default infinite)

       -S message_size
              The size of each message transferred, in bytes.  (default 100)

       -P     Run  the  server  in  persistent  mode.  This allows multiple rping clients to connect to a single
              server instance. The server will run until killed.

NOTES

       Because this test maps RDMA resources to userspace, users must ensure that  they  have  available  system
       resources and permissions.  See the libibverbs README file for additional details.
