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.   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.
