NAME

       udpong - unreliable datagram streaming over RDMA ping-pong test.

SYNOPSIS

       udpong [-s server_address] [-b bind_address]
                      [-B buffer_size] [-C transfer_count]
                      [-S transfer_size] [-p server_port] [-T test_option]

DESCRIPTION

       Uses  unreliable  datagram  streaming over RDMA protocol (rsocket) to connect and exchange
       data between a client and server application.

OPTIONS

       -s server_address
              The network name or IP address of the server system listening for connections.  The
              used name or address must route over an RDMA device.  This option must be specified
              by the client.

       -b bind_address
              The local network address to bind to.

       -B buffer_size
              Indicates the size of the send and receive network buffers.

       -C transfer_count
              The number of messages to transfer from the client to the server and back again  on
              each iteration.  (default 1000)

       -S transfer_size
              The size of each send transfer, in bytes.  (default 1000)

       -p server_port
              The server's port number.

       -T test_option
              Specifies test parameters.  Available options are:

       s | socket  - uses standard socket calls to transfer data

       a | async - uses asynchronous operation (e.g. select / poll)

       b | blocking - uses blocking calls

       n | nonblocking - uses non-blocking calls

       e | echo - server echoes all messages

NOTES

       Basic  usage  is  to  start udpong on a server system, then run udpong -s server_name on a
       client system.  udpong will run a series  of  latency  and  bandwidth  performance  tests.
       Specifying  a  different  transfer_count  or transfer_size will run a user customized test
       using default values where none have been specified.

       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.
