[-f address_format] [-P port_space]
[-c connections] [-C message_count] [-S message_size] [-a ack_timeout]
ucmatose -s server_address [-b bind_address]
[-f address_format] [-P port_space]
[-c connections] [-C message_count] [-S message_size] [-t tos] [-a ack_timeout]
Описание (Description)
Establishes a set of reliable RDMA connections between two nodes
using the librdmacm, optionally transfers data between the nodes,
then disconnects.
Параметры (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. To bind to any
address with IPv6 use -b ::0 .
-f address_format
Specifies the format of the server and bind address. Be
default, the format is determined by getaddrinfo() as
either being a hostname, an IPv4 address, or an IPv6
address. This option may be used to indicate that a
specific address format has been provided. Supported
address_format values are: name, ip, ipv6, and gid.
-P port_space
Specifies the port space for the connection. Be default,
the port space is the RDMA TCP port space. (Note that the
RDMA port space may be separate from that used for IP.)
Supported port_space values are: tcp and ib.
-c connections
The number of connections to establish between the client
and server. (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. (default
100)
-t tos Indicates the type of service used for the communication.
Type of service is implementation dependent based on
subnet configuration.
-a ack_timeout
Indicates the QP ACK timeout value that should be used.
The value calculated according to the formula 4.096 *
2^(ack_timeout) usec.
-m Tests event channel migration. Migrates all communication
identifiers to a different event channel for disconnect
events.
Примечание (Note)
Basic usage is to start ucmatose on a server system, then run
ucmatose -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.
