qperf SERVERNODE [OPTIONS] TESTS
|
|
|
|
Description
|
|
qperf measures bandwidth and latency between two nodes. It can work
|
|
over TCP/IP as well as the RDMA transports. On one of the nodes, qperf
|
|
is typically run with no arguments designating it the server node. One
|
|
may then run qperf on a client node to obtain measurements such as
|
|
bandwidth, latency and cpu utilization.
|
|
|
|
In its most basic form, qperf is run on one node in server mode by
|
|
invoking it with no arguments. On the other node, it is run with two
|
|
arguments: the name of the server node followed by the name of the
|
|
test. A list of tests can be found in the section, TESTS. A variety
|
|
of options may also be specified.
|
|
|
|
One can get more detailed information on qperf by using the --help
|
|
option. Below are examples of using the --help option:

Bugs
|
|
None of the RDMA tests are available if qperf is compiled without the RDMA
|
|
libraries. The -f option is not yet implemented in many of the tests.

Examples
|
|
In these examples, we first run qperf on a node called myserver in server
|
|
mode by invoking it with no arguments. In all the subsequent examples, we
|
|
run qperf on another node and connect to the server which we assume has a
|
|
hostname of myserver.
|
|
* To run a TCP bandwidth and latency test:
|
|
qperf myserver tcp_bw tcp_lat
|
|
* To run a SDP bandwidth test for 10 seconds:
|
|
qperf myserver -t 10 sdp_bw
|
|
* To run a UDP latency test and then cause the server to terminate:
|
|
qperf myserver udp_lat quit
|
|
* To measure the RDMA UD latency and bandwidth:
|
|
qperf myserver ud_lat ud_bw
|
|
* To measure RDMA UC bi-directional bandwidth:
|
|
qperf myserver rc_bi_bw

|
same port on both the server and client machines. The default value
|

|
--msg_size Size (-m)
|
|
Set the message size to Size. The default value varies by test. It

kib or K, mib or M, or gib or G indicates that the size is being
|
|
specified in kibibytes, mebibytes or gibibytes respectively while a

trailing kb or k, mb or m, or gb or g indicates kilobytes, megabytes
|
|
or gigabytes respectively.

relevant for the socket tests and refers to the TCP/UDP/SDP/RDS/SCTP
|
|
port that the test is run on.
|
|
--precision Digits (-e)
|
|
Set the number of significant digits that are used to report results.
|
|
--rd_atomic Max (-nr)
|
|
Set the number of in-flight operations that can be handled for a RDMA

read or atomic operation to Max. This is only relevant to the RDMA
|
|
Read and Atomic tests.

|
|
--rem_rd_atomic Max (-rnr)

|
|
level is 0.
|
|

|
|
--rem_service_level SL (-rsl)

|
|
m, h or d indicates that the time is specified in minutes, hours or
|
|
days respectively.
|
|
--timeout Time (-to)
|
|
Set timeout to Time. This is the timeout used for various things
|
|
such as exchanging messages. The default is 5 seconds.
|
|
--loc_timeout Time (-lto)
|
|
Set local timeout to Time. This may be used on the server to set
|
|
the timeout when initially exchanging data with each client.
|
|
However, as soon as we receive the client's parameters, the client's
|
|
remote timeout will override this parameter.
|
|
--rem_timeout Time (-rto)
|
|
Set remote timeout to Time.
|
|
--unify_nodes (-un)
|
|
Unify the nodes. Describe them in terms of local and remote rather
|
|
than send and receive.
|
|
--unify_units (-uu)
|
|
Unify the units that results are shown in. Uses the lowest common
|
|
denominator. Helpful for scripts.
|
|
--use_bits_per_sec (-ub)
|
|
Use bits/sec rather than bytes/sec when displaying networking speed.
|
|
--use_cm OnOff (-cm)
|
|
Use the RDMA Connection Manager (CM) if OnOff is non-zero. It is
|
|
necessary to use the CM for iWARP devices. The default is to
|
|
establish the connection without using the CM. This only works for
|
|
the tests that use the RC transport.
|
|
-cm1
|
|
Use RDMA Connection Manager.
|
|

|
|

|
|
Provide information on parameters used.
|
|
--verbose_more (-vv)
|
|

|
|
-vvu.
|
|

|
|
--verbose_more_stat (-vvs)
|

|
|
seconds before giving up.
