.SH "DESCRIPTION"
|
|
Establishes a set of reliable RDMA connections between two nodes using the
|
|
librdmacm, optionally transfers data between the nodes, then disconnects.
|
|
.SH "OPTIONS"
|
|
.TP
|
|
\-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.
|
|
.TP
|
|
\-b bind_address
|
|
The local network address to bind to.
|
|
To bind to any address with IPv6 use -b ::0 .
|
|
.TP
|
|
\-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.
|
|
.TP
|
|
\-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.
|
|
.TP
|
|
\-c connections
|
|
The number of connections to establish between the client and server.
|
|
(default 1)
|
|
.TP
|
|
\-C message_count
|
|
The number of messages to transfer over each connection. (default 10)
|
|
.TP
|
|
\-S message_size
|
|
The size of each message transferred, in bytes. (default 100)
|
|
.TP
|
|
\-t tos
|
|
Indicates the type of service used for the communication. Type of service
|
|
is implementation dependent based on subnet configuration.
|
|
.TP
|
|
\-m
|
|
Tests event channel migration. Migrates all communication identifiers to
|
|
a different event channel for disconnect events.
|
|
.SH "NOTES"
|
|
Basic usage is to start ucmatose on a server system, then run
|
|
ucmatose -s server_name on a client system.
|
|
.P
|
|
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.
