.SH "DESCRIPTION"
|
|
Determines min and max times for various "steps" in RDMA CM
|
|
connection setup and teardown between a client and server
|
|
application.
|
|
|
|
"Steps" that are timed are: create id, bind address, resolve address,
|
|
resolve route, create qp, connect, disconnect, and destroy.
|
|
.SH "OPTIONS"
|

|
|
\-s server_address

\-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 100)
|
|
.TP
|
|
\-p port_number
|
|
The server's port number.
|
|
.TP
|
|
\-r retries
|
|
Number of retries when resolving address or route. (default 2)
|
|
.TP
|
|
\-t timeout_ms
|
|
Timeout in millseconds (ms) when resolving address or
|
|
route. (default 2000 - 2 seconds)
|
|
.SH "NOTES"
|
|
Basic usage is to start cmtime on a server system, then run
|
|
cmtime -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.
