[ofa-general] Problem while running ib tests

[Karun Sharma]

I am referring to ib_send_bw, ib_read_bw, ib_write_bw etc. 

Usage:
  ib_read_bw            start a server and wait for connection
  ib_read_bw <host>     connect to server at <host>

Options:
  -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>   use port <port> of IB device (default 1)
  -m, --mtu=<mtu>        mtu size (256 - 4096. default for hermon is 2048)
  -o, --outs=<num>       num of outstanding read/atom(default 4)
  -s, --size=<size>      size of message to exchange (default 65536)
  -a, --all              Run sizes from 2 till 2^23
  -t, --tx-depth=<dep>   size of tx queue (default 100)
  -n, --iters=<iters>    number of exchanges (at least 2, default 1000)
  -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 taken from command line (for RDMAoE index should be 0)
  -b, --bidirectional    measure bidirectional bandwidth (default unidirectional)
  -V, --version          display version number
  -e, --events           sleep on CQ events (default poll)
  -F, --CPU-freq         do not fail even if cpufreq_ondemand module is loaded

Which commands are you referring to with the "-F" option?

I just did a pull from git://git.openfabrics.org/~mst/perftest.git and I don't see a -F for the commands there.  Have these tools moved?  Or are you speaking of other tools?

I also run into this problem and I have resorted to turning off cpuspeed.

Thanks,
Ira
