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

SYNOPSIS

              rdma_bw [-p, --port=<port>] [-d, --ib-dev=<dev>]
                    [-i, --ib-port=<port number.] [-s, --size=<size>]

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

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)
