DESCRIPTION
The rdma_bw and rdma_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.
#rdma_bw
Then an active sending instance is started, giving it the address at
which it will find a listening passive receiver.
#rdma_bw server
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)
-s, --size <size>
Size of message to exchange (default 2)
-n, --iters <iterations>
Number of exchanges (at least 5, default 1000)
-t, --tx-depth <depth>
Size of tx queue (default 50)
-S, --sl <sl>
SL (default 0)
-I, --inline_size <size>
Max size of message to be sent in inline (default 0)
-b, --bidirectional
Measure bidirectional bandwidth (default unidirectional)
-c, --cma
use RDMA CM
-C, --report-cycles
report times in cpu cycle units (default microseconds)
-H, --report-histogram
Print out all results (default print summary only)
-U, --report-unsorted
(implies -H) print out unsorted results (default sorted)
