UDADDY(1) librdmacm UDADDY(1)
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.
-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.
-b bind_address
The local network address to bind to. To bind to any address
with IPv6 use -b ::0 .
-c connections
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)
-C message_count
The number of messages to transfer over each connection.
(default 10)
-S message_size
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
configuration.
-p port_space
The port space of the datagram communication. May be either
the RDMA UDP (0x0111) or IPoIB (0x0002) port space. (default
RDMA_PS_UDP)
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.
