NAME         top

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

SYNOPSIS         top

       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         top

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

OPTIONS         top

       -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

       -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         top

       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.
