RDMA_BW(1)(1) General Commands Manual RDMA_BW(1)(1) NAME rdma_bw, rdma_lat - Bandwidth and latency test using RDMA write trans- actions. 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>] [-C, --report-cycles] [-H, --report-histogram] [-U, --report-unsorted] [-c, --cma] [server] 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) ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+-----------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+-----------------------+ |Availability | network/open-fabrics | +---------------+-----------------------+ |Stability | Pass-through volatile | +---------------+-----------------------+ SEE ALSO ib_write_bw(1), ib_write_lat(1), ib_send_lat(1), ib_read_bw(1), ib_send_bw(1), ib_read_lat(1), ib_clock_test(8), ib_write_bw_postlist(1) NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
