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.
