The "perftest" utilities are micro bench mark utilities. First a passive receiving instance is started. #ib_read_bw Then an active sending instance is started, giving it the address at which it will find a listening passive receiver. #ib_read_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) -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 -b, --bidirectional Measure bidirectional bandwidth (default unidirectional) -e, --events Sleep on CQ events (default poll) -N, --no peak-bw Cancel peak-bw calculation (default with peak) -o, --outs <num> Specify <num> as number of outstanding read/atom(default max of device) -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) ATTRIBUTES See attributes(5) for descriptions of the following attributes: +---------------+----------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+----------------------+ |Availability | network/open-fabrics | +---------------+----------------------+ |Stability | Volatile | +---------------+----------------------+ SEE ALSO ib_write_bw(1), ib_send_bw(1), rdma_lat(1), ib_write_bw_postlist(1), rdma_bw(1), ib_write_lat(1), ib_send_lat(1), ib_clock_test(1) NOTES This software was built from source available at https://java.net/projects/solaris-userland.
