rdma_bw, rdma_lat - Bandwith and latency test using RDMA write transactions.

rdma_bw [-p, --port=<port>] [-d, --ib-dev=<dev>]
 [-i, --ib-port=<port number.] [-s, --size=<size>]
 [-n, --iters=<iterations>] [-t, --tx-depth=<depth>]
 [-S, --sl=<sl>] [-b, --bidirectional] [-c, --cma]
 [server]

rdma_lat [-p, --port=<port>] [-d, --ib-dev=<dev>]
 [-i, --ib-port=<port number.] [-s, --size=<size>]
 [-n, --iters=<iterations>] [-t, --tx-depth=<depth>]

 [-U, --report-unsorted] [-c, --cma] [server]

.Nm 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.

Then an active sending instance is started, giving it the address at which it will find a listening passive receiver.

If options are used then the same options must be used for both client and server.

The following options are available for use on the command line:

7 -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)
