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

SYNOPSIS
     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>]
                [-S, --sl=<sl>] [--I, --inline_size=<size>]

DESCRIPTION
     The rdma_bw and rdma_lat tests are part  of  the  "perftest"
     utilities that  are  used  for  InfiniBand  related  perfor-
     mance  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>

User Commands                                 RDMA_BW/RDMA_LAT(1)



            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>

     -I, --inline_size <size>
            Max size of message to be sent in inline (default 0)

     -b, --bidirectional
            Measure  bidirectional  bandwidth  (default unidirec-
            tional)

     -c, --cma
            use RDMA CM

     -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)
