.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.
|
|
.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.
