DESCRIPTION
The ib_write_bw, ib_write_bw_postlist and ib_write_lat tests
are part of the "perftest" utilities that are used for
InfiniBand related performance testing. The "perftest"
utilities are micro bench mark utilities.
First a passive receiving instance is started.
#ib_write_bw
Then an active sending instance is started, giving it the
address at which it will find a listening passive receiver.
#ib_write_bw server

User Commands IB_WRITE_BW/IB_WRITE_BW_POST_LIST/IB_WRITE_LAT(1)
If options are used then the same options must be used for
both client and server.
OPTIONS
The following options are available for use on the command
line:
-p, --port <port>
Listen on/connect to port <port> (default 18515)
-d, --ib-dev <dev>
Use IB device <dev> (default first device found)
-i, --ib-port <port number>
Use port <port number> of IB device (default 1)
-c, --connection <RC|UD>
Connection type RC or UD (default RC)
-m, --mtu <mtu>s
Mtu size : 256 - 4096 (default port mtu)
-s, --size <size>
Size of message to exchange (default 2)
-a, --all
Run sizes from 2 till 2^23
-n, --iters <iterations>
Number of exchanges (at least 5, default 1000)
-t, --tx-depth <depth>
Size of tx queue (default 50)
-u, --qp-timeout <timeout>
QP timeout, timeout value is 4 usec * 2 ^(timeout),
default 14
-S, --sl <sl>
SL (default 0)
-x, --gid-index <index>
Test uses GID with GID index (Default : IB - no gid)
-F, --CPU-freq
Do not fail even if cpufreq_ondemand module is loaded
-V, --version
Display version number
-I, --inline_size <size>
SunOS 5.11 Last change: Oct 15, 2011 2
User Commands IB_WRITE_BW/IB_WRITE_BW_POST_LIST/IB_WRITE_LAT(1)
Max size of message to be sent in inline (default 0)
-b, --bidirectional
Measure bidirectional bandwidth (default unidirec-
tional)
-N, --no peak-bw
Cancel peak-bw calculation (default with peak)
-q, --qp <num>
Specify <num> as number of QPs to use (default 1).
-C, --report-cycles
report times in cpu cycle units (default microsec-
onds)
-H, --report-histogram
Print out all results (default print summary only)
-U, --report-unsorted
(implies -H) print out unsorted results (default
sorted)
