ibv_rc_pingpong - simple InfiniBand RC transport test

ibv_rc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-l sl] [-e]
Run a simple ping-pong test over InfiniBand via the reliable connected (RC) transport.
OPTIONS -p, --port=PORT
use TCP port PORT for initial synchronization (default 18515)
use IB device DEVICE (default first device found)
use IB port PORT (default port 1)
ping-pong messages of size SIZE (default 4096)
post DEPTH receives at a time (default 1000)
perform ITERS message exchanges (default 1000)
use SL as the service level value of the QP (default 0)
sleep while waiting for work completion events (default is to poll for completions)

The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some

UDADDY(1) librdmacm UDADDY(1)NAME
udaddy - RDMA CM datagram setup and simple ping-pong test.
udaddy [-s server_address] [-b bind_address] [-c connections]
[-C message_count] [-S message_size] [-p port_space]
udaddy -s server_address [-b bind_address] [-c connections]
[-C message_count] [-S message_size] [-t tos] [-p port_space]
Establishes a set of unreliable RDMA datagram communication paths between two nodes using the librdmacm, optionally transfers datagrams
between the nodes, then tears down the communication.
OPTIONS -s server_address
The network name or IP address of the server system listening for communication. The used name or address must route over an RDMA
device. This option must be specified by the client.
The local network address to bind to.
The number of communication paths to establish between the client and server. The test uses unreliable datagram communication, so
no actual connections are formed. (default 1)
The number of messages to transfer over each connection. (default 10)
The size of each message transferred, in bytes. This value must be smaller than the MTU of the underlying RDMA transport, or an
error will occur. (default 100)
-t tos Indicates the type of service used for the communication. Type of service is implementation dependent based on subnet configura-
The port space of the datagram communication. May be either the RDMA UDP (0x0111) or IPoIB (0x0002) port space. (default
Basic usage is to start udaddy on a server system, then run udaddy -s server_name on a client system.
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.
