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] [-I address] -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.

       -I address
              The address to bind to as the source IP address to use. This is useful if you  have
              multiple addresses on the same network or complex routing.

       -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.

       -q     Control QP Creation/Modification directly from the application, instead of rdma_cm.

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.
