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
