Имя (Name)
udaddy - RDMA CM datagram setup and simple ping-pong test.
Синопсис (Synopsis)
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]
Описание (Description)
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.
Параметры (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.
-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)
Примечание (Note)
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.
