In a recent posting, Don Capps described this:
     Iozone is able to run across multiple nodes. See the -+m and -t options.
     It knows how to use rsh and can also use any remote execution
     method by simply setting the environmental variable RSH to
     whatever works for you. Example: RSH=ssh ; export RSH

Which kind of problems do you experience?
