ibv_rc_pingpong - simple InfiniBand RC transport test
SYNOPSIS
ibv_rc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-l sl] [-e] HOSTNAME
ibv_rc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-l sl] [-e]
DESCRIPTION
Run a simple ping-pong test over InfiniBand via the reliable connected (RC) transport.
OPTIONS -p, --port=PORT
use TCP port PORT for initial synchronization (default 18515)
-d, --ib-dev=DEVICE
use IB device DEVICE (default first device found)
-i, --ib-port=PORT
use IB port PORT (default port 1)
-s, --size=SIZE
ping-pong messages of size SIZE (default 4096)
-r, --rx-depth=DEPTH
post DEPTH receives at a time (default 1000)
-n, --iters=ITERS
perform ITERS message exchanges (default 1000)
-l, --sl=SL
use SL as the service level value of the QP (default 0)
-e, --events
sleep while waiting for work completion events (default is to poll for completions)

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.

SMPDUMP(8) Open IB Diagnostics SMPDUMP(8)NAME
SMPDUMP -
dump InfiniBand subnet management attributes
SYNOPSIS
smpdump [options] <dlid|dr_path> <attribute> [attribute_modifier]
DESCRIPTION
smpdump is a general purpose SMP utility which gets SM attributes from a specified SMA. The result is dumped in hex by default.
OPTIONS
dlid|drpath
LID or DR path to SMA
attribute
IBA attribute ID for SM attribute
attribute_modifier
IBA modifier for SM attribute
-s, --string
Print strings in packet if possible
Addressing Flags
-D, --Direct The address specified is a directed route
Examples:
[options] -D [options] "0" # self port
[options] -D [options] "0,1,2,1,4" # out via port 1, then 2, ...
(Note the second number in the path specified must match the port being
used. This can be specified using the port selection flag '-P' or the
port found through the automatic selection process.)
-L, --Lid The address specified is a LID
Port Selection flags
-C, --Ca <ca_name> use the specified ca_name.
-P, --Port <ca_port> use the specified ca_port.
Local port Selection
Multiple port/Multiple CA support: when no IB device or port is specified (see the "local umad parameters" below), the libibumad library
selects the port to use by the following criteria:
1. the first port that is ACTIVE.
2. if not found, the first port that is UP (physical link up).
If a port and/or CA name is specified, the libibumad library attempts to fulfill the user request, and will fail if it is not possible.
For example:
ibaddr # use the first port (criteria #1 above)
ibaddr -C mthca1 # pick the best port from "mthca1" only.
ibaddr -P 2 # use the second (active/up) port from the first available IB device.
ibaddr -C mthca0 -P 2 # use the specified port only.
Debugging flags
-d raise the IB debugging level. May be used several times (-ddd or -d -d -d).
-e show send and receive errors (timeouts and others)
-h, --help show the usage message
-v, --verbose
increase the application verbosity level. May be used several times (-vv or -v -v -v)
-V, --version show the version info.
Configuration flags
-t, --timeout <timeout_ms> override the default timeout for the solicited mads.
--config, -z <config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf
